Scenarios included in the BROWSE Sample Clauses

Scenarios included in the BROWSE model‌ The current BROWSE model for residents and bystanders includes exposure to spray drift from boom and orchard (air blast) sprayers during a spray application, as well as exposure to vapour and deposited spray drift following an application, assuming residents and bystanders are immediately downwind of the application. The model is appropriate for a wide range of agricultural crops, including all outdoor field crops sprayed with a conventional boom, and fruit crops sprayed with an air blast sprayer. The model does not explicitly include exposure to amenity applications (e.g. parks, golf courses) although the boom sprayer model can be extended to include operating conditions typical of many vehicle-mounted amenity applications. The model does not include exposure from contact with treated agricultural crops (e.g. from walking through a recently sprayed cereal crop). This could be addressed, however, by using models of worker exposure, or by extending the resident and bystander model of exposure to turf contaminated with spray drift. The model excludes exposure to dust from airborne soil, from drilling treated seeds or from harvesting crops because there was no data available at the start of the project, and still inadequate data for model development, for estimating the quantity of active substance emitted from these operations. The model does not currently calculate exposure of residents and bystanders to emissions from protected crop structures.
