本研究调查了有机磷农药 (OPP) 的吸入暴露，并评估了 Bang-Rieng 农业社区蔬菜种植者的相关健康风险。使用个人采样泵收集空气样本，并将吸附剂管放置在蔬菜种植者的呼吸区。在雨季和旱季收集样品。对 33 名蔬菜种植者和 17 名参考对象的有机磷农药（毒死蜱、百防磷和丙溴磷）残留进行了分析。结果显示，农场地区空气中 OPPs 的中位浓度范围为 0.022–0.056 mg/m3，非农场地区空气中 OPPs 的中位浓度范围为 <0.0016–<0.005mg/m3。两个季节菜农体内三种农药的浓度均显着高于参考值。研究结果还表明，蔬菜种植者在施药、混合、装载和喷洒过程中可能因吸入毒死蜱和百防磷而面临急性不良反应的风险。建议当局和社区实施适当的风险降低和风险管理策略。
This study investigated inhalation exposure to organophosphate pesticides (OPPs) and evaluated the associated health risks to vegetable growers living in the Bang-Rieng agricultural community. Air samples were collected by using personal sampling pumps with sorbent tubes placed in the vegetable growers' breathing zone. Samples were collected during both wet and dry seasons. Residues of organophosphate pesticides, that is, chlorpyrifos, dicrotofos, and profenofos, were analyzed from 33 vegetable growers and 17 reference subjects. Results showed that median concentrations of OPPs in air in farm areas were in the range of 0.022–0.056 mg/m3 and air in nonfarm areas in the range of <0.0016–<0.005 mg/m3. The concentration of the three pesticides in the vegetable growers was significantly higher than that of the references during both seasons. The results also indicate that the vegetable growers may be at risk for acute adverse effects via the inhalation of chlorpyrifos and dicrotofos during pesticide application, mixing, loading, and spraying. It is suggested that authorities and the community should implement appropriate strategies concerning risk reduction and risk management.
