| Abstract/Contents: | "Dermal contact with dislodgeable residues of pesticides from recently treated turfgrass areas in golf courses may result in golfer exposure. Florida researchers used two pesticides to measure the extent to which applied pesticides can be transferred to golfers playing a round of golf. Dislodgeable residues of chlorpyrifos and isazofos were determined by various methods, in an attempt to simulate a golfer's dermal and oral pathways. Several methods of sampling were used in determining dislodgeable residues. Less than 2 % of applied isazofos could be recovered from the turf surface by vigorous wiping action immediately after application. Following irrigation and drying, at four h ours [hours] after application, isazofos residues decreased 94% following a scheduled irrigation event. At 24 hours after application residues averaged 0.02[]% of the isazofos applied, chlorpyrifos residues on clubface, golf balls, and golf grips declines rapidly after application. A 95% reduction occurred between the one and four-hour sampling periods for chlorpyrifos detected on club face. Chlorpyrifos resiudes on golf grips were only detected one hour after application. The data indicate that even under extreme circumstances, golfers will experience little risk from dislodgeable resiudes of chlorpyrifos. While the data for isazofos appears more threatening, it should be remembered that golfers are unlikely to encounter these pesticides on every round of golf they play over a period of many years." |
