Combined turf transferrable residue, air monitoring, and terrestrial field dissipation studies were performed from a single application of Dylox 420 SL, an organophosphate insecticide containing trichlorfon, to turf plots with and without watering. Due to the short half-lives of trichlorfon and its metabolites, analytical methods were developed to rapidly process and analyze air tube, cloth dosimeter and soil samples collected from the field site. These samples were analyzed for residues of trichlorfon, dichlorvos (DDVP), desmethyl-DDVP and dichloroacetic acid to provide data for exposure modeling for both applicators and bystanders.
