泰国农业学家在农业地区大量使用百草枯来控制杂草和草。该研究确定了泰国背负式喷雾器使用者的百草枯接触情况，并确定了职业接触的决定因素。呼吸区的空气和皮肤样品收集了57背包喷雾器，而喷雾。在喷洒前一天、喷洒事件结束时和喷洒后第二天收集点尿样。调查对象接受了关于一般人口统计、农业活动、农药施用和施用百草枯时使用的个人防护设备的访谈。采用高效液相色谱荧光检测器测定了尿液、空气和皮肤样品中百草枯的浓度。喷洒前一天、喷洒结束时和喷洒后第二天尿中百草枯浓度的中位数IQR分别为2.51（0.81-5.59）、8.23（3.3-13.73）和3.48（1.03-8.19）μg/g肌酐。空气样本和皮肤总接触浓度分别为5.15（2.28-10.12）微克/立方米和92.66（34.37-1647.46）微克/小时。使用电池供电的背负式喷雾器和站在逆风处有效地减少了吸入暴露。穿着长袖衬衫、长裤、靴子、乳胶手套和巴拉克拉瓦可以降低背包式喷雾器皮肤接触的百草枯浓度。
Thai agriculturists heavily used paraquat in agricultural areas to control weed and grasses. This study determined paraquat exposure among backpack sprayers in Thailand and identified determinants of occupational exposure. Breathing zone air and dermal samples were collected from 57 backpack sprayers while spraying. Spot urine samples were collected on the day before spraying, end of spraying event and the next day after spraying. The subjects were interviewed about general demographics, agricultural activities, pesticide application and personal protective equipment used while applying paraquat. Paraquat concentrations in urine samples, air samples and dermal samples were determined by HPLC with a fluorescence detector. The median IQR of urinary paraquat concentrations on the day before spraying, end of spraying event, the next day after spraying were 2.51 (0.81–5.59), 8.23 (3.3–13.73) and 3.48 (1.03–8.19) μg/g creatinine, respectively. Concentrations of air samples and total dermal exposures were 5.15 (2.28–10.12) μg/m3and 92.66 (34.37–1647.46) μg/hr, respectively. Use of battery powered backpack sprayer and standing upwind effectively reduced inhalation exposures. Wearing a long sleeve shirt, long pants, boots, latex gloves and balaclava could reduce paraquat concentration on dermal exposure among backpack sprayers.
