Abstract/Contents:Investigates volitilization as a route of pesticide loss on turfgrass, and as a means of potential exposure to golfers. "Volatile residues were determined from small circular turf plots with high volume air samplers using the Theoretical Profile Shape method and dislodgeable residues were concurrently determined by wiping treated turfgrass with water-dampened cheesecloth. Inhaled doses were estimated from the volatile residues and dermal doses were estimated using the dislodgeable residues. Inhalation and dermal hazards were the determined using the USEPA Hazard Quotient (HQ) method." Ten of the pesticides tested were deemed safe "in that their application never resulted in HQ greater than 1.0." Also examined the use of spray tank adjuvants to "mitigate the exposure potential of the organophosphorous insecticides that have high vapor pressures and inherent high toxicity." Pesticides not deemed safe by the HQ method were all organophosphorous insecticides with high vapor pressures and inherent high toxicity.
