2. Operational conditions and risk management measures | ||||
2.1 Control of workers exposure | ||||
Product characteristic | ||||
Sodium hydrogensulfate is produced and placed on the market as a pearled/granular product or in preparations having the same physical form. The rotating drum method (RDM) according to Heubach was used to determine the particle size distribution of the airborne fraction of dust generated during mechanical agitation simulating workplace conditions. This method provides a “total dustiness“ value indicating the propensity of a material to become airborne, and thus serving as an indicator of the emission potential of the material under workplace conditions. The test resulted in a total dustiness of sodium hydrogensulfate of 0.8 % when simulating mechanical agitation (e.g. bagging, filling and mixing operations). According to the MEASE approach, the substance intrinsic emission potential could be assessed as very low – low. Thus, inhalation exposure to sodium hydrogensulfate is assumed to be negligible during all process steps in industrial and/or professional settings and the inhalation route is not a relevant exposure route for this substance. Under the prerequisite that all available (i.e. purchasable) forms of sodium hydrogensulfate are in accordance with the dustiness as documented above, human health is thereby considered to be sufficiently protected. It is noted that the substance intrinsic emission potential may be overwritten for specific processes by the process intrinsic emission potential. PROC 7 and PROC 11 as being spray applications in industrial and non-industrial settings, respectively, are assumed to result in a higher emission potential (it is also assumed that the physical form has to be modified to powder prior to spraying). Since PROC 21 and PROC 24 are considered as potential abrasive tasks, the emission potential is accordingly higher and the physical form is assumed to be wear dust during these tasks. | ||||
PROC | Use in preparation | Content in preparation | Physical form | Emission potential |
PROC 7 | not restricted | powder | medium | |
PROC 21, 24 | (wear) dust | low – high | ||
All other applicable PROCs | pearls, granules | very low – low | ||
Amounts used | ||||
The actual tonnage handled per shift is not considered to influence the exposure as such for this scenario. Instead, the combination of the scale of operation (industrial vs. professional) and level of containment/automation (as reflected in the PROC) is the main determinant of the process intrinsic emission potential. | ||||
Frequency and duration of use/exposure | ||||
PROC | Duration of exposure | |||
PROC 7 | Due to the high level of automation and measures at the process level (please see below), inhalation exposure is negligible and the exposure duration is consequently short (< 60 minutes). | |||
All other applicable PROCs | not restricted | |||
Human factors not influenced by risk management | ||||
The shift breathing volume during all process steps reflected in the PROCs is assumed to be 10 m³/shift (8 hours). | ||||
Other given operational conditions affecting workers exposure | ||||
Other operational conditions such as room volume, indoor or outdoor use, process temperature and process pressure are not considered relevant for the occupational exposure assessment of the conducted processes. | ||||
Technical conditions and measures at process level (source) to prevent release | ||||
PROC | Level of containment | Level of segregation | ||
PROC 1, 2, 3 | closed process | not required | ||
PROC 7 | closed process | spraying of sodium hydrogensulfate in a segregated spray tower where direct exposure of the worker is excluded | ||
All other applicable PROCs | Risk management measures at the process level (e.g. containment or segregation of the emission source) are generally not required in these processes since any potential inhalation exposure is assumed to be negligible due to the low dusty nature of sodium hydrogensulfate. | |||
Technical conditions and measures to control dispersion from source towards the worker | ||||
PROC | Level of separation | Localised controls (LC) | Efficiency of LC (according to MEASE) | Further information |
PROC 7 | Any potentially required separation of workers from the emission source is indicated above under “Frequency and duration of exposure”. A reduction of exposure duration can be achieved, for example, by the installation of ventilated (positive pressure) control rooms or by removing the worker from workplaces involved with relevant exposure. | Efficient ventilation of the area (e.g. local exhaust ventilation) is recommended to minimise any potential emission of wear dust into workplace air. | 78 % | - |
All other applicable PROCs | Separation of workers from the emission source is generally not required in the conducted processes. | |||
Organisational measures to prevent /limit releases, dispersion and exposure | ||||
Avoid inhalation or ingestion. General occupational hygiene measures are required to ensure safe handling of the substance. Good occupational hygiene practices have to be followed (e.g. shower and change clothes at end of work shift) to avoid any contamination of private households via the work-home-interface. Do not eat and smoke in the workplace. Unless otherwise stated below, wear standard working clothes and shoes. Do not wear contaminated clothing at home. Do not blow dust off with compressed air. Regular training in workplace hygiene practice and proper use of personal protective equipment is required. | ||||

PROC | Specification of respiratory protective equipment (RPE) | RPE efficiency (assigned protection factor, APF) | Specification of gloves | Further personal protective equipment (PPE) |
All applicable PROCs | If ventilation is insufficient and/or formation of relevant dust levels cannot be excluded, use RPE according to EN143 and EN149. An FFP2 mask should be worn for safety reasons when packaging/unpacking sodium hydrogensulfate since high abrasion may occur. | (APF=10, for safety reasons during processes where relevant dust levels and high abrasion may occur) | In cases where extensive direct contact with sodium hydrogensulfate cannot be avoided, wear suitable protective gloves according to EN374. | Eye protection equipment (e.g. goggles or visors) conforming to EN166 must be worn, unless potential contact with the eye can be excluded by the nature and type of application (i.e. closed process). Additionally, face protection, protective clothing and safety shoes are required to be worn as appropriate. |
Any RPE as defined above shall only be worn if the following principles are implemented in parallel: The duration of work (compare with “duration of exposure” above) should reflect the additional physiological stress for the worker due to the breathing resistance and mass of the RPE itself, due to the increased thermal stress by enclosing the head. In addition, it shall be considered that the worker’s capability of using tools and of communicating are reduced during the wearing of RPE. For reasons as given above, the worker should therefore be (i) healthy (especially in view of medical problems that may affect the use of RPE), (ii) have suitable facial characteristics reducing leakages between face and mask (in view of scares and facial hair). The recommended devices above which rely on a tight face seal will not provide the required protection unless they fit the contours of the face properly and securely. The employer and self-employed persons have legal responsibilities for the maintenance and issue of respiratory protective devices and the management of their correct use in the workplace. Therefore, they should define and document a suitable policy for a respiratory protective device programme including training of the workers. An overview of the APFs of different RPE (according to BS EN 529:2005) can be found in the glossary of MEASE. | ||||
2.2 Control of environmental exposure | ||||

Technical onsite conditions and measures to reduce or limit discharges, air emissions and releases to soil | ||||
Risk management measures related to the environment aim to avoid discharging NaHSO4 solutions into municipal wastewater or to surface water, in case such discharges are expected to cause significant pH changes regular control of the pH value during introduction into open waters is required. In general discharges should be carried out such that pH changes in receiving surface waters are minimised (e.g. through neutralisation). In general most aquatic organisms can tolerate pH values in the range of 6-9. This is also reflected in the description of standard OECD tests with aquatic organisms. Neutralisation of waste waters and effluent should be widespread (often it is also required by national legislation). | ||||
Conditions and measures related to waste | ||||
Solid industrial waste of NaHSO4 should be reused or discharged to the industrial wastewater and further neutralized if needed. | ||||
3. Exposure estimation and reference to its source | ||||
Occupational exposure | ||||
PROC | Method used for inhalation exposure assessment (refer to introduction) | Inhalation exposure estimate (RCR) | Method used for dermal exposure assessment | Dermal exposure estimate (RCR) |
All applicable PROCs | Since sodium hydrogensulfate has a low dustiness (<1 % as obtained in rotating drum testing), inhalation exposure during all process steps is assumed to be negligible if the proposed risk management measures as described above are met. | Due to the negligible dermal absorption of sodium hydrogensulfate, the dermal route is not a relevant exposure path for sodium hydrogensulfate and a dermal DNEL has not been derived. Thus, dermal exposure is not assessed in this exposure scenario. | ||
Environmental emissions | |
The environmental exposure assessment is only relevant for the aquatic environment, when applicable including STPs/WWTPs, as emissions of NaHSO4 in the different life-cycle stages (production and use) mainly apply to (waste) water. The aquatic effect and risk assessment only deal with the effect on organisms/ecosystems due to possible pH changes related to H+ discharges, being the toxicity of Na+ and SO 2- are expected to be negligible compared to the (potential) pH effect. Only the local scale is addressed, including 4 municipal sewage treatment plants (STPs) or industrial waste water treatment plants (WWTPs) when applicable, both for production and industrial use as any effects that might occur would be expected to take place on a local scale. The high water solubility and very low vapour pressure indicate that NaHSO4 will be found predominantly in water. Significant emissions or exposure to air are not expected due to the low vapour pressure of NaHSO4. Significant emissions or exposure to the terrestrial environment are not expected either for this exposure scenario. | |
Environmental emissions | The production or use of NaHSO4 can potentially result in an aquatic emission and locally increase the NaHSO4 concentration and affect the pH in the aquatic environment. When the pH is not neutralised, the discharge of effluent from NaHSO4 production or use sites may impact the pH in the receiving water. The pH of effluents is normally measured very frequently and can be neutralised easily as often required by national laws. |
Exposure concentration in waste water treatment plant (WWTP) | Waste water from NaHSO4 production or use is an inorganic wastewater stream and therefore there is no biological treatment. Therefore, wastewater streams from NaHSO4 production sites will normally not be treated in biological waste water treatment plants (WWTPs). |
Exposure concentration in aquatic pelagic compartment | When NaHSO4 is emitted to surface water, sorption to particulate matter and sediment will be negligible. When NaHSO4 is rejected to surface water, the pH may decrease, depending on the buffer capacity of the water. The higher the buffer capacity of the water, the lower the effect on pH will be. In general the buffer capacity preventing shifts in acidity or alkalinity in natural waters is regulated by the equilibrium between carbon dioxide (CO2), the bicarbonate ion (HCO -) and the carbonate ion (CO 2-). 3 3 |
Exposure concentration in sediments | The sediment compartment is not included in this ES, because it is not considered relevant for NaHSO4: when NaHSO4 is emitted to the aquatic compartment, sorption of to sediment particles is negligible. |
Exposure concentrations in soil and groundwater | The terrestrial compartment is not included in this exposure scenario, because it is not considered to be relevant. |
Exposure concentration in atmospheric compartment | The air compartment is not included in this CSA because it is considered not relevant for NaHSO4. |
Exposure concentration relevant for the food chain (secondary poisoning) | Bioaccumulation in organisms is not relevant for NaHSO4: a risk assessment for secondary poisoning is therefore not required. |
4. Guidance to DU to evaluate whether he works inside the boundaries set by the ES | |
Occupational exposure | |
The DU works inside the boundaries set by the ES if he handles sodium hydrogensulfate having the same properties with regard to dustiness as described in this ES and if the proposed risk management measures as described above are met. A dustiness assessment can be made either on a qualitative or on a quantitative basis. For a qualitative assessment the MEASE glossary (xxx.xxxx.xx/xxxxx.xxxx) can be consulted, which provides guidance on this topic. A quantitative assessment can be done by conducting a dustiness test with the specific material according to the rotating drum method. It is however noted that also other dustiness tests exist, which may be used instead. For further details please refer to the European Standard EN 15051 titled “Workplace atmospheres – Measurement of the dustiness of bulk materials – Requirements and reference test methods”. | |
Environmental emissions
If a site does not comply with the conditions stipulated in the safe use ES, it is recommended to apply a tiered approach to perform a more site-specific assessment. For that assessment, the following tiered approach is recommended.
Tier 1: retrieve information on effluent pH and the contribution of NaHSO4 on the resulting pH. Shall the pH be bellow 6 and predominantly dependent by the NaHSO4, than further actions are required to demonstrate safe use.
Tier 2a: retrieve information on receiving water pH after the discharge point. The pH of the receiving water shall not be lower then 6. If the measures are not available, the pH in the river can be calculated as follows:
⎡Qeffluent *10 pHeffluent + Qriverupstream *10pHupstream ⎤
⎦
pHriver = Log⎢
⎣
Qriverupstream + Qeffluent ⎥
(Eq 1)
Where:
Q effluent refers to the effluent flow (in m3/day)
Q river upstream refers to the upstream river flow (in m3/day) pH effluent refers to the pH of the effluent
pH upstream river refers to the pH of the river upstream of the discharge point Please note that initially, default values can be used:
• Q river upstream flows: use the 10th of existing measurements distribution or use default value of 18000 m3/day
• Q effluent: use default value of 2000 m3/day
• The upstream pH is preferably a measured value. If not available, one can assume a neutral pH of 7 if this can be justified.
Such equation has to be seen as a worst case scenario, where water conditions are standard and not case specific.
Tier 2b: Equation 1 can be used to identify which effluent pH causes an acceptable pH level in the receiving body. In order to do so, pH of the river is set at value 6 and pH of the effluent is calculated accordingly (using default values as reported previously, if necessary). As temperature influences solubility, pH effluent might require to be adjusted on a case-by-case basis. Once the maximum admissible pH value in the effluent is established, it is assumed that the H+ concentrations are all dependent on NaHSO4 discharge and that there is no buffer capacity conditions to consider (this is a unrealistic worst case scenario, which can be modified where information is available). Maximum load of NaHSO4 that can be annually rejected without negatively affecting the pH of the receiving water is calculated assuming chemical equilibrium. H+ expressed as moles/litre is multiplied by average flow of the effluent and then divided by the molar mass of NaHSO4.
Tier 3: measure the pH in the receiving water after the discharge point. If pH is between 6 and 9, safe use is reasonably demonstrated and the ES ends here. If pH is found to be below 6, risk management measures have to be implemented: the effluent has to undergo neutralisation, thus ensuring safe use of NaHSO4 during production or use phase.

Assessment Method | Occupational exposure: A qualitative assessment of inhalation and dermal exposure was conducted in the absence of any DNELs (derived no-effect levels) for inhalation and dermal exposure. Environmental exposure: A qualitative assessment was conducted. | |||
2. Operational conditions and risk management measures | ||||
2.1 Control of workers exposure | ||||
Product characteristic | ||||
Sodium hydrogensulfate is produced and placed on the market as a pearled/granular product or in preparations having the same physical form. The rotating drum method (RDM) according to Heubach was used to determine the particle size distribution of the airborne fraction of dust generated during mechanical agitation simulating workplace conditions. This method provides a “total dustiness“ value indicating the propensity of a material to become airborne, and thus serving as an indicator of the emission potential of the material under workplace conditions. The test resulted in a total dustiness of sodium hydrogensulfate of 0.8 % when simulating mechanical agitation (e.g. bagging, filling and mixing operations). According to the MEASE approach, the substance intrinsic emission potential could be assessed as very low – low. Thus, inhalation exposure to sodium hydrogensulfate is assumed to be negligible during all process steps in industrial and/or professional settings and the inhalation route is not a relevant exposure route for this substance. Under the prerequisite that all available (i.e. purchasable) forms of sodium hydrogensulfate are in accordance with the dustiness as documented above, human health is thereby considered to be sufficiently protected. It is noted that the substance intrinsic emission potential may be overwritten for specific processes by the process intrinsic emission potential. PROC 7 and PROC 11 as being spray applications in industrial and non-industrial settings, respectively, are assumed to result in a higher emission potential (it is also assumed that the physical form has to be modified to powder prior to spraying). Since PROC 21 and PROC 24 are considered as potential abrasive tasks, the emission potential is accordingly higher and the physical form is assumed to be wear dust during these tasks. | ||||
PROC | Use in preparation | Content in preparation | Physical form | Emission potential |
PROC 11 | not restricted | powder | medium | |
PROC 21, 24 | (wear) dust | low – high | ||
All other applicable PROCs | pearls, granules | very low – low | ||
Amounts used | ||||
The actual tonnage handled per shift is not considered to influence the exposure as such for this scenario. Instead, the combination of the scale of operation (industrial vs. professional) and level of containment/automation (as reflected in the PROC) is the main determinant of the process intrinsic emission potential. | ||||
Frequency and duration of use/exposure | ||||
PROC | Duration of exposure | |||
PROC 11 | Due to the high level of automation and measures at the process level (please see below), inhalation exposure is negligible and the exposure duration is consequently short (< 60 minutes). | |||
All other applicable PROCs | not restricted | |||
Human factors not influenced by risk management | ||||
The shift breathing volume during all process steps reflected in the PROCs is assumed to be 10 m³/shift (8 hours). | ||||
Other given operational conditions affecting workers exposure | ||||
Other operational conditions such as room volume, indoor or outdoor use, process temperature and process pressure are not considered relevant for the occupational exposure assessment of the conducted processes. | ||||
Technical conditions and measures at process level (source) to prevent release | ||||
PROC | Level of containment | Level of segregation | ||
PROC 2, 3 | closed process | not required | ||
PROC 11 | closed process | spraying in non-industrial settings has to be performed in segregated areas where direct exposure of the worker is excluded | ||
All other applicable PROCs | Risk management measures at the process level (e.g. containment or segregation of the emission source) are generally not required in these processes since any potential inhalation exposure is assumed to be negligible due to the low dusty nature of sodium hydrogensulfate. | |||
Technical conditions and measures to control dispersion from source towards the worker | ||||
PROC | Level of separation | Localised controls (LC) | Efficiency of LC (according to MEASE) | Further information |
PROC 11 | Any potentially required separation of workers from the emission source is indicated above under “Frequency and duration of exposure”. A reduction of exposure duration can be achieved, for example, by the installation of ventilated (positive pressure) control rooms or by removing the worker from workplaces involved with relevant exposure. | Efficient ventilation of the area (e.g. local exhaust ventilation) is recommended to minimise any potential emission of wear dust into workplace air. | 78 % | - |
All other applicable PROCs | Separation of workers from the emission source is generally not required in the conducted processes. | |||
Organisational measures to prevent /limit releases, dispersion and exposure | ||||
Avoid inhalation or ingestion. General occupational hygiene measures are required to ensure safe handling of the substance. Good occupational hygiene practices have to be followed (e.g. shower and change clothes at end of work shift) to avoid any contamination of private households via the work-home-interface. Do not eat and smoke in the workplace. Unless otherwise stated below, wear standard working clothes and shoes. Do not wear contaminated clothing at home. Do not blow dust off with compressed air.

Conditions and measures related to personal protection, hygiene and health evaluation | ||||
PROC | Specification of respiratory protective equipment (RPE) | RPE efficiency (assigned protection factor, APF) | Specification of gloves | Further personal protective equipment (PPE) |
All applicable PROCs | If ventilation is insufficient and/or formation of relevant dust levels cannot be excluded, use RPE according to EN143 and EN149. An FFP2 mask should be worn for safety reasons when packaging/unpacking sodium hydrogensulfate since high abrasion may occur. | (APF=10, for safety reasons during processes where relevant dust levels and high abrasion may occur) | In cases where extensive direct contact with sodium hydrogensulfate cannot be avoided, wear suitable protective gloves according to EN374. | Eye protection equipment (e.g. goggles or visors) conforming to EN166 must be worn, unless potential contact with the eye can be excluded by the nature and type of application (i.e. closed process). Additionally, face protection, protective clothing and safety shoes are required to be worn as appropriate. |
Any RPE as defined above shall only be worn if the following principles are implemented in parallel: The duration of work (compare with “duration of exposure” above) should reflect the additional physiological stress for the worker due to the breathing resistance and mass of the RPE itself, due to the increased thermal stress by enclosing the head. In addition, it shall be considered that the worker’s capability of using tools and of communicating are reduced during the wearing of RPE. For reasons as given above, the worker should therefore be (i) healthy (especially in view of medical problems that may affect the use of RPE), (ii) have suitable facial characteristics reducing leakages between face and mask (in view of scares and facial hair). The recommended devices above which rely on a tight face seal will not provide the required protection unless they fit the contours of the face properly and securely. The employer and self-employed persons have legal responsibilities for the maintenance and issue of respiratory protective devices and the management of their correct use in the workplace. Therefore, they should define and document a suitable policy for a respiratory protective device programme including training of the workers.

2.2 Control of environmental exposure | ||||
Amounts used | ||||
The daily and annual amount per site (for point sources) is not considered to be the main determinant for environmental exposure. In this scenario the emissions of NaHSO4 are considered in lower amounts and on a larger scale due to professional and/or consumer use. | ||||

Thus, dermal exposure is not assessed in this exposure scenario. | ||
Environmental emissions | ||||
Environmental emissions | Wide dispersive uses of NaHSO4 usually use diluted products. The small amounts of NaHSO4 will entirely end up in the sewer where they will further be neutralized quickly by the buffer capacity of the wastewater before reaching a STP or surface water. The influent of a municipal STP is typically tested for pH and, if needed, adjusted before entering the biological step. The effluent of a municipal STP is usually circum- neutrual. | |||
Exposure concentration in waste water treatment plant | Since the municipal STP usually monitors the pH of the influent and neutralize accordingly if needed, there is no pH impact expected on the microbiological activity in the municipal STP. | |||
Exposure concentration in aquatic pelagic compartment | When NaHSO4 is emitted to surface water, sorption to particulate matter and sediment will be negligible.

Appendix 2: Exposure Scenario Format (2) addressing uses carried out by consumers | |
there are no data available which indicate systemic toxicity following this route. Thus, dermal exposure is not assessed in this exposure scenario. | |
Eye | Qualitative assessment Exposure to the eyes is not expected as part of the intended product use. Solid: As the product is of low-very low dustiness no dust formation is expected. Liquid: Splashes into the eyes cannot be excluded if no protective goggles are worn during the application. However,this will mainly be to the diluted application solution (<1% NaHSO4). Therefore mild irritation can easily be avoided by immediate rinsing of the eyes with water. |
Inhalation | Sodium hydrogensulfate has a low dustiness (<1 % as obtained in rotating drum testing), therefore inhalation exposure during use of solid sodium hydrogensulfate pearls is assumed to be negligible. Thus, inhalation exposure is not assessed in this exposure scenario. |
Environmental exposure | |
The pH impact due to use of sodium hydrogensulfate in household cleaning products is expected to be negligible. The influent of a municipal wastewater treatment plant is often neutralized anyway and sodium hydrogensulfate may even be used beneficially for pH control of basic wastewater streams that are treated in biological WWTPs. Since the pH of the influent of the municipal treatment plant is circum neutral, the pH impact is negligible on the receiving environmental compartments, such as surface water, sediment and terrestrial compartment. | |

Human exposure | |
Use of pH-regulator for swimming pools | |
Route of exposure | Method used, comments |
Oral | Qualitative assessment Oral uptake of sodium hydrogensulfate as pH-regulator of swimming pools is not considered under normal handling conditions. |
Dermal | No local effects are known after dermal exposure. Furthermore, dermal absorption is considered negligible and there are no data available which indicate systemic toxicity following this route. Thus, dermal exposure is not assessed in this exposure scenario. |
Inhalation | Sodium hydrogensulfate has a low dustiness (<1 % as obtained in rotating drum testing), therefore inhalation exposure during use of solid sodium hydrogensulfate pearls is assumed to be negligible. Thus, inhalation exposure is not assessed in this exposure scenario. |
Eye | Qualitative assessment Exposure to the eyes is not expected as part of the intended product use. Solid: As the product is of low-very low dustiness no dust formation is expected. Liquid: However, splashes into the eyes cannot be excluded if no protective goggles are worn during the task described . Prompt rinsing with water and seeking medical advice after accidental exposure is advisable. |
Post-application ingestion: | |
Route of exposure | Method used, comments |
Oral | Qualitative assessment: Sodium hydrogensulfate will dissolve in water to sodium and sulphate ions and will reduces the pH of the swimming pool water. If an equal distribution of the salt has been secured and the pH was measured to be in the desired range between 7.0-7.4 no local effects need to be suspected. No systemic effects are expected from the oral uptake, as these ions are omnipresent in nature and normal constituent of the human body. |
Environmental exposure | |
The pH impact due to use of sodium hydrogensulfate as pH-regulator in residential swimming pools is expected to be negligible, as under normal use conditions the desired effect is to neutralize the pH of the swimming pool water. However, the influent of a municipal wastewater treatment plant is often neutralized anyway and sodium hydrogensulfate may even be used beneficially for pH control of basic wastewater streams that are treated in biological WWTPs. Since the pH of the influent of the municipal treatment plant is circum neutral, the pH impact is negligible on the receiving environmental compartments, such as surface water, sediment and terrestrial compartment. | |
4. Guidance to DU to evaluate whether he works inside the boundaries set by the ES | |
The DU works inside the boundaries set by the ES if sodium hydrogensulfate is either marked as a liquid preparation or in case of a solid preparation sodium hydrogensulfate is used as manufactured and not further processed to get smaller particles. | |
10 Risk Characterisation
10.1 Industrial uses of NaHSO4
10.1.1 Occupational exposure
Please refer to Section 3 of exposure scenario 9.1. Inhalation and dermal exposure have been addressed qualitatively in the absence of any DNELs (derived no-effect levels).
10.1.2 Environmental exposure
As shown in the exposure scenario 9.1, no exposure to NaHSO4 is expected to occur in sediments, soil and groundwater or atmospheric compartment.
10.1.2.1 Aquatic compartment (including microbiological activity in STP)
The risk characterisation is only performed for the aquatic environment compartment, when applicable including STPs/WWTPs, as emissions of NaHSO4 in the different life-cycle stages (production and use) mainly apply to (waste) water.
Discharges of NaHSO4 from production and use to STPs/WWTPs and receiving waters are generally well controlled. Additionally, national regulations often require pH control of the wastewaters, to protect surface waters from pH changes. Where a significant pH change cannot be excluded, neutralisation of NaHSO4 containing wastewaters and effluents applies.
Therefore, the aquatic compartment is adequately protected with respect to pH changes.
10.2 Wide dispersive uses of NaHSO4
10.2.1 Occupational exposure
Please refer to Section 3 of exposure scenario 9.2. Inhalation and dermal exposure have been addressed qualitatively in the absence of any DNELs (derived no-effect levels).
10.2.2 Environmental exposure
10.2.2.1 Aquatic compartment (including microbiological activity in STP)
The risk characterisation is only performed for the aquatic environment compartment and the municipal STPs, as emissions of NaHSO4 in the different life-cycle stages mainly apply to (waste) water.
Discharges of NaHSO4 from wide dispersive use to the STPs are generally quickly neutralized in the sewer. Additionally, the municipal STP will analyse the pH of the influent and effluent to protect the biological step in the STP and the receiving water from pH changes. Where a significant pH change cannot be excluded, neutralisation of NaHSO4 containing wastewaters applies.
Therefore, the aquatic compartment is adequately protected with respect to pH changes.
10.3 Consumer uses of NaHSO4
10.3.1 Consumer exposure
No quantitative assessment has been performed; therefore no risk characterisation ratio (RCR) has been derived.
Regarding the irritant effect to the eyes sodium hydrogensulfate can be allocated to the severe hazard category on the basis that exposure to such irritant substances should be avoided. Exposure to the eyes is not expected as part of the intended product use. However, accidental splashes cannot be excluded. However, it can be assumed that this would be to the diluted form rather than the concentrate. Therefore, mild irritation can easily be avoided by immediate rinsing of the eyes with water.
10.3.2 Environmental exposure
Consumer uses relate to already diluted products which will further be neutralized quickly in the sewer, well before reaching a WWTP or surface water. The influent of municipal treatment plants is usually neutralized anyway. Therefore, consumer use of sodium hydrogensulfate is adequately under control for the environment.
