Volatilization can be a major route of pesticide loss following application to turfgrass. Consequently, a significant proportion of applied pesticides may be available for human exposure via volatile and dislodgeable foliar residues. Our research has established that there are volatile and dislodgeable residues available for golfer exposure following pesticide application to turfgrass and not all of these exposures can be deemed completely safe using the USEPA Hazard Quotient assessment. Of the 14 pesticides examined, 10 never resulted in an inhalation exposure situation that had a Hazard Quotient greater than 1.0. Five never resulted in a dermal exposure situation that resulted in a Hazard Quotient greater than 1.0 and after the first day following application, 9 had Hazard Quotients less that 1.0. Application of ethoprop, isazofos, diazinon and isofenphos, however, did result in Hazard Quotients greater than 1.0 over a period of 3 days post-application and hence the safety of exposure
