| Abstract/Contents: | "University of Massachussets [Massachusetts] scientists quantified foliar dislodgeable residues and utilized dosimetry and biomonitoring techniques to assess exposure of volunteers to commonly used pesticides as volunteers were simulating rounds of golf. Three widely used insecticides, chlorpyrifos, cyfluthrin, and carbaryl were evaluated in over 150 rounds of golf. In all cases, exposure to these insecticides under worst case scenarios were signifigantly less than established acceptable daily dose (ADI) and USEPA Office of Pesticide Program reference dose (Rfd) criteria. Other findings include: Dermal absorption is the most signifigant route of exposure to golfers following application of currently-used turfgrass pesticides. Lower legs, arms and hands are most vulnerable. Exposure estimates using biomonitoring data are 2 to 15-fold less than previous estimates using environmental (airborne and dislodgeable foliar) residue data. Exposure to chlorpyrifos (new rate), carbaryl, and cyfluthrin under worst case scenarios are all signifigantly less than established acceptable daily dose (ADI) and USEPA/OPP reference dose based Hazard Quotient (HQ) critera. The highest USEPA Hazard Quotient value determined (0.079) using dosimetry and/or biomonitoring techniques following application of chlorpyrifos at the current USEPA approved maximum label rate occured during the full-course applications, indicating that additional management practices willl lead to even greater safety margins. Several management practices, including the optimal use of post-application irrigation, enforcement of reentry intervals, use of less-toxic pesticides, and partial course applications signifigantly reduced exposure." |
