A large part of the world's agricultural production, despite its adverse effects on human health and water resources, depends on the use of pesticides. Despite strict regulations, the use of pesticides continues around the world. This study aimed to determine the residual concentrations of malathion and diazinon in samples of drinking water resources. To achieve this goal, 384 samples from 8 various sites from January to December 2020 were analyzed using gas chromatography (GC) with an electron capture detector (ECD) and liquid-liquid extraction technique. Besides, statistical analysis and a risk-modeling approach supported by an automatic Monte-Carlo procedure were applied. The results showed that there is a high carcinogenic risk regarding malathion and that the low age population is at the most non-carcinogenic risk regarding diazinon.
尽管农药对人类健康和水资源有不利影响，但世界上很大一部分农业生产仍依赖农药的使用。尽管有严格的规定，世界各地仍在继续使用农药。本研究旨在测定饮用水源样本中马拉硫磷和二嗪农的残留浓度。为实现这一目标，于2020年1月至12月从8个不同地点采集了384个样本，采用带有电子捕获检测器（ECD）的气相色谱法（GC）和液液萃取技术进行分析。此外，还应用了统计分析和由自动蒙特卡洛程序支持的风险建模方法。结果表明，马拉硫磷存在较高的致癌风险，而低年龄段人群中二嗪农的非致癌风险最高。
