Rapid industrialization and urbanization have led to severe pollution into water resources which limits to reach safe drinking and irrigation water globally. One of the most important pollutants of environment that brought along with industrialization and technology are pesticides. In this study, it was aimed to investigate the pesticide residues in Dim Stream, due to intense touristic and agricultural activities in the region. Thus, four locations alongside the river were selected for sampling to evaluate the pesticide residue in the stream. The water samples were collected representing the rainy and dry seasons and extracted according to the Quechers method which is validated in terms of accuracy, specificity, limit of detection (LOD), and quantification (LOQ). Pesticide residues were analyzed by injecting LC-MSMS and GC-MS. The most recurrent pesticides were cypermethrin, endosulfan, deltamethrin, dicofol, metribuzin, parathion-methyl, permethrin, malathion, and tetradifon in the samples. Some of the levels of pesticides detected in water were significantly high compared with guideline values set by the Surface Water Quality Regulation of Turkey, EU, and World Health Organization, and this may be hazardous to aquatic life and human health. The obtained 18 recoveries of pesticides in the samples varied between 70 and 120%. LOD was ranged 19 from 0.23 to 9.67 μg/L. LOQ of 11 of the pesticides were higher than 1 μg/L.

在水环境中分析农药残留的方法验证。

快速的工业化和城市化已导致对水资源的严重污染，这限制了全球安全饮用水和灌溉水的供应。工业化和技术带来的最重要的环境污染物之一是农药。在这项研究中，其目的是调查由于该地区的大量旅游和农业活动而在Dim Stream中产生的农药残留。因此，选择了沿河的四个位置进行采样，以评估河流中的农药残留。收集代表雨季和干旱季节的水样，并根据Quechers方法提取水样，该方法在准确性，特异性，检测限（LOD）和定量（LOQ）方面均得到验证。通过注射LC-MSMS和GC-MS分析农药残留。样品中最常使用的农药是氯氰菊酯，硫丹，溴氰菊酯，三氯杀螨醇，甲丁嗪，甲基对硫磷，苄氯菊酯，马拉硫磷和丁苯磺隆。与土耳其，欧盟和世界卫生组织的《地表水水质条例》设定的准则值相比，水中检出的某些农药水平明显偏高，这可能对水生生物和人类健康构成危害。样品中获得的18种农药回收率在70％至120％之间。LOD在0.23至9.67μg/ L之间的范围为19。11种农药的LOQ高于1μg/ L。与土耳其，欧盟和世界卫生组织的《地表水水质条例》设定的准则值相比，水中检出的某些农药水平明显偏高，这可能对水生生物和人类健康构成危害。样品中获得的18种农药回收率在70％至120％之间。LOD在0.23至9.67μg/ L之间的范围为19。11种农药的LOQ高于1μg/ L。与土耳其，欧盟和世界卫生组织的《地表水水质条例》设定的准则值相比，水中检出的某些农药水平明显偏高，这可能对水生生物和人类健康构成危害。样品中获得的18种农药回收率在70％至120％之间。LOD在0.23至9.67μg/ L之间的范围为19。11种农药的LOQ高于1μg/ L。
