A study was conducted to determine exposure of plantation workers to glyphosate while performing mist blower foliar application of Roundup herbicide according to label directions and under actual use conditions. Exposure was determined by passive dosimetry techniques while workers sprayed weeds around palm trees in a plantation in Malaysia. The workers were fitted with gauze patches at different locations on their clothing air sampling was performed in the breathing zone and the worker's hands were washed at the end of the day. The mean body were dose estimate for a fully clothed worker was 4.14 x 10-3 mg per kg per lb of glyphosate applied. This estimate is almost identical to that measured in a study of U.S. forestry workers applying Roundup herbicide with backpack sprayers. Thus mist blower application of Roundup was found to be safe for the workers.

Abstract

A study was conducted to determine exposure of plantation workers to glyphosate while performing mist blower foliar application of Roundup herbicide according to label directions and under actual use conditions. Exposure was determined by passive dosimetry techniques while workers sprayed weeds around palm trees in a plantation in Malaysia. The workers were fitted with gauze patches at different locations on their clothing air sampling was performed in the breathing zone and the worker's hands were washed at the end of the day. The mean body were dose estimate for a fully clothed worker was 4.14 x 10-3 mg per kg per lb of glyphosate applied. This estimate is almost identical to that measured in a study of U.S. forestry workers applying Roundup herbicide with backpack sprayers. Thus mist blower application of Roundup was found to be safe for the workers.
