Relative source contribution definition

Relative source contribution or "RSC" means the factor (percentage) used in calculating an HNV or HNC to account for all sources of exposure to a contaminant. The RSC reflects the percent of total exposure that may be attributed to surface water through water intake and fish consumption.

Examples of Relative source contribution in a sentence

• Relative source contribution analysis compares the magnitude of exposure expected via drinking water to the magnitude of exposure from intake of naphthalene in other media such as food, air, and soil.

• Relative source contribution values are typically reported for PM studies and if a normalization species is specified the ranked value output also provides the percent and confidence intervals.

• The fact that the results do not change considerably when adjustments are made for attrition and sample selection demonstrates the robustness of this relationship across the two countries, despite small differences in the samples between the full original sample from the PASEC surveys in the mid-1990s, and the long panel of cohort members that we were able to track over the 17-year interval in Senegal.

• Hereinafter, the programme shall be referred to as 'Rooftop PV & Small Solar Power Generation Programme' (RPSSGP).

• The HQ equation is given as: = +× ( × ) (Equation 2-5) Where:Iw = exposure through drinking water consumption (mg/day).If = exposure through fish consumption (mg/day)RfD = parameter specific reference dose (mg/kg-day)RSC = Relative source contribution factor expressed as percentage of RfDapportioned to surface water exposuresBW = body weight (kg) The equation for calculating the incremental increase in cancer risk is similar to the hazard quotient equation used for non-carcinogens.

• RSC = Relative source contribution factor of 0.8. An RSC derived from actual exposure data may be developed using the methodology outlined by the 1980 National Guidelines (see 45 FR 79354).

• Relative source contribution brought a lengthy discussion on the part of the peer review workgroup and as an extensive discussion from the Agency.
