TDI-Brooks International has been awarded a contract by the USEPA to chemically analyze multi-media samples that have been collected from six homes for the organophosphate insecticide, diazinon, and its metabolite, diazoxon. An exposure monitoring study was conducted in the Spring of 2001 in six homes to examine the fate and transport of diazinon following granular turf applications. This current research project expands upon that study to consider pet dogs as a vehicle for the physical translocation of diazinon residues and the potential for transfer of residues to the human occupants following hand-to-dog contacts. A total of 300 multi-media residential and 72 quality assurance/quality control (QA/QC) samples were collected. The samples consist of granular diazinon formulation, polyurethane foam (PUF) air monitors, PUF rollers, isopropanol wipes using gauze pads, household dust, doormat sweepings, dog fur clippings, cotton gloves, and soil.
The contract number is RFQ-RT-03-00006 and is effective December 2002. The contract amount is $55,000.
