Exposure of forest workers to herbicides

Abstract

The purpose of this study was to measure workers’ exposure to MCPA and glyphosate when sprayers connected to the brush saws was used. A non-pressurized sprayer with a pump and a pressurized sprayer where dosage was regulated with manual control were studied. Exposure was measured from the breathing zone and urine samples. MCPA collected from the breathing zone gathered into alcohol was 0.05 mg/m for the pressurized sprayer, 0.02 mg/m for the non-pressurized sprayer, and 0.04 mg/m (average) for both types of sprayers together.3333333
