THE POTENTIAL FOR HUMAN EXPOSURES TO PET-BORNE DIAZINON RESIDUES FOLLOWING RESIDENTIAL LAWN APPLICATIONS
MORGAN, M. K., D. M. STOUT, AND P. P. EGEGHY. THE POTENTIAL FOR HUMAN EXPOSURES TO PET-BORNE DIAZINON RESIDUES FOLLOWING RESIDENTIAL LAWN APPLICATIONS. Presented at American Chemical Society,Spring National Meeting, Chicago, IL, March 25 - 29, 2007.
This observational study examined the potential for indoor/outdoor pet dogs to be an important pathway for transporting diazinon residues into homes and onto occupants following residential lawn applications. The primary objective was to investigate the potential exposures of children and their pet dogs to diazinon after a lawn application at their homes.
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.
