Levels of eight different types of organophosphorous pesticides in water samples from different parts of the Shahid Rajaei dam reservoir in north of Iran were monitored. Water samples were collected from different locations of the reservoir in June, July and September of 2015 and in February 2016. Water samples were extracted with dichloromethane solvent and quantified using gas chromatography and mass spectrometry analyses. The results showed that all pesticides were detected for all periods and include dichlorvos, trifluralin, diazinon, methyl parathion, fenitrothion, malathion, profenofos and ethion. The highest concentrations were found in the summer that is related to malathion (on average 0.78 μg L). In midwinter, no pesticide residues were detected. The results showed that concentration of single and total pesticides for all stations were greater than the maximum contamination level of the European Economic Commission.
对伊朗北部沙希德拉贾伊大坝水库不同区域水样中8种不同类型有机磷农药的含量进行了监测。于2015年6月、7月、9月及2016年2月从水库不同位置采集水样。水样用二氯甲烷溶剂萃取，并用气相色谱和质谱分析进行定量。结果表明，所有时期均检测到了所有农药，包括敌敌畏、氟乐灵、二嗪农、甲基对硫磷、杀螟硫磷、马拉硫磷、丙溴磷和乙硫磷。夏季发现的浓度最高，这与马拉硫磷有关（平均0.78μg L）。在冬季中期，未检测到农药残留。结果表明，所有监测站的单一农药和总农药浓度均高于欧洲经济委员会的最大污染水平。
