Abstract: | "BACKGROUND: We determined the characteristics and evaluated associated risks of sprayed pesticide exposure among workers cultivating Korean cabbage. The test pesticide, a mixture of 3% chlorantraniliprole and 4% indoxacarb wettable granules diluted 2000 times, was sprayed on Korean cabbage within a 3000 m(2) area in Goesan, Korea. Dermal exposures were measured using a whole-body dosimetry method. RESULTS: Exposure to chlorantraniliprole was observed among ten individuals, ranging from 140.4 to 4234.0 microg person(-1) . The legs were the most prominent exposure area (86.35%), with the face being the least exposed (0.06%). Exposure risk was assessed by calculating the margin of safety (MOS) on the exposure amount for each body part. The MOS based on dermal and inhalation exposure doses ranged from 59 to 1765. CONCLUSION: Exposure was the greatest for the legs, probably as a result of the low height of the crop and the use of a long-wand sprayer. An MOS value >1 indicates a low risk for applicators using this method of application. However, with tall crops, exposure level and MOS values can vary widely, as MOS increases or decreases based on exposure dose. Therefore, future research is needed to better understand appropriate safety precautions when working with potent pesticides. (c) 2018 Society of Chemical Industry" |
