在泰国，草甘膦是一种流行的除草剂，用于控制农业部门的害虫。本研究旨在通过吸入、皮肤接触和尿草甘膦浓度测量43名喷洒草甘膦的菜农的草甘膦暴露浓度。使用4种喷雾设备：手动泵背包3个，电动喷雾背包22个，电池泵背包16个，高压泵2个。用玻璃纤维过滤器采集呼吸区空气样品，用100 cm~2棉布贴在10个体位采集皮肤接触性样品，分别于喷药前1天晨尿、喷药结束前1天晨尿、喷药次日晨尿3个时间点采集尿样。结果表明，草甘膦暴露呼吸区浓度的几何平均值为9.37g/m~3(10.17μg/m~3)。皮肤贴片总暴露浓度的GM(GSD)为7.57(0.01)mg/h，腿部、背部和手臂是暴露最严重的部位。使用手工背包的菜农尿草甘膦含量最高，为46.90(1.35)μg/g肌酐。农民应佩戴口罩和靴子，以减少通过吸入和皮肤接触而接触草甘膦。
In Thailand, glyphosate is popular herbicide to control pests in the agricultural sector. This study aimed to measure glyphosate exposure concentrations through inhalation, dermal contact, and urinary glyphosate concentrations among 43 vegetable farmers spraying glyphosate in Bungphra Subdistrict, Phitsanulok Province. Four types of spraying equipment were used, manual pump backpack (n = 3), motorized spray backpack (n = 22), battery pump backpack (n = 16), and high pressure pump (n = 2). Breathing zone air samples were collected using glass fiber filters; dermal contact samples were collected using 100 cm2 cotton patches attached on 10 body locations and urine samples were collected at 3 time points: morning void urine the day before spraying, the end of spraying event, and the morning void urine the next day of spraying. The results showed that the geometric mean (GM; geometric standard deviation [GSD]) of breathing zone concentrations of glyphosate exposure were 9.37 (10.17) μg/m3. The GM (GSD) of total dermal patches exposure concentrations were 7.57 (0.01) mg/h. The legs, back, and arms were the most exposed body areas. The GM (GSD) of urinary glyphosate was found highest among vegetable farmers using manual backpack 46.90 (1.35) μg/g creatinine. Farmers should wear masks and boots to reduce glyphosate exposure by inhalation and dermal contact.
