Impact/Purpose:
The objectives for this task are to
Compile results and important findings from NERL-sponsored children's exposure studies;
Determine which pathways produce the greatest contribution to aggregate exposure among children for specific classes of pesticides;
Identify and quantify the factors that influence pesticide exposures among children;
Develop input parameters (e.g. multimedia pesticide distributions, exposure factor data) for exposure and dose models for assessing aggregate exposures and cumulative risks;
Evaluate exposure and dose models, including algorithms for estimating route-specific exposures, against real world data; and
Identify additional data gaps for modeling aggregate exposure and dose.
Description:
The Children's Exposure Research Program in the National Exposure Research Laboratory has supported numerous laboratory and field studies to reduce uncertainty in the exposure estimates with the goal of ensuring that pesticides are regulated appropriately. These studies were conducted to identify pesticide use patterns, measure pesticide concentrations in homes and day care centers, describe spatial and temporal distributions of pesticide concentrations following residential applications, evaluate approaches for estimating dermal and non-dietary exposure, and characterize activity patterns of young children.
