农药有毒,可能对人类和生态系统产生负面影响。基奇纳排水沟是埃及最长的排水沟之一,输送来自农业部门的各种废水,其中含有杀虫剂,可能会污染生态系统。因此,水质,人类健康风险,以及来自KitchenerDrain-埃及的非洲cat鱼和尼罗罗非鱼中的农药积累。水和鱼类样本是从KafrElsheikh省的KitchenerDrain收集的,埃及,在四个季节。结果表明,在四个季节中未检测到七氯和二嗪农。然而,硫丹,毒死蜱,在冬季和秋季检测到三氯杀螨醇。只有p,p'-在春季检测到DDT。硫丹,七氯,冬季在尼罗罗非鱼中检测到艾氏剂。春季仅检测到七氯和艾氏剂。硫丹,七氯,三氯杀螨醇,p,p\'-滴滴涕,毒死蜱,在秋季检测到二嗪农。在夏天,三氯杀螨醇和p,p'-检测到滴滴涕,而硫丹,七氯磷,p\'-滴滴涕,艾氏剂,毒死蜱,和二嗪农未检测到。在非洲鲶鱼中,硫丹,七氯,三氯杀螨醇,P,p'-在冬季检测到DDT,而毒死蜱,艾氏剂,和毒死蜱,艾氏剂,和二嗪农未检测到。在春天的季节,硫丹,七氯,和艾氏剂被检测到。硫丹,七氯,三氯杀螨醇,p,p\'-滴滴涕,艾氏剂,毒死蜱,在秋季检测到二嗪农。同样,在夏季,硫丹,七氯,三氯杀螨醇,p,p\'-滴滴涕,艾氏剂,毒死蜱,和二嗪农被检测到。尼罗罗非鱼在四个季节的估计日摄入量(EDI)顺序是七氯>硫丹>三氯杀螨醇>p,p'-DDT>艾氏剂>二嗪农>毒死蜱。在四个季节中,非洲cat鱼的EDI顺序为硫丹>p,p'-滴滴涕>七氯>艾氏剂>三氯杀螨醇>二嗪农>毒死蜱。总之,结果证实,食用从基奇纳下水道收集的尼罗罗非鱼和非洲cat鱼没有危害指数。
Pesticides are toxic and could negatively impact humans and the ecosystem. The Kitchener Drain is among the longest drains in Egypt and carries a wide range of wastewater from the agriculture sector, which contains pesticides and may pollute the ecosystem. Thus, water quality, human health risk, and pesticide accumulation in African catfish and Nile tilapia from the Kitchener Drain-Egypt. The water and fish samples were collected from Kitchener Drain in Kafr Elsheikh Governorate, Egypt, during the four seasons. The results indicated that heptachlor and diazinon were undetected during the four seasons. However, endosulfan, chlorpyrifos, and dicofol were detected in winter and autumn. Only p,p\'-DDT was detected during spring. Endosulfan, heptachlor, and
aldrin were detected in Nile tilapia during winter. Only heptachlor and
aldrin were detected during spring. Endosulfan, heptachlor, dicofol, p,p\'-DDT, chlorpyrifos, and diazinon were detected in the autumn season. In summer, dicofol and p,p\'-DDT were detected, while endosulfan, heptachlor p,p\'-DDT, aldrin, chlorpyrifos, and diazinon were not detected. In African catfish, endosulfan, heptachlor, dicofol, and p,p\'-DDT were detected during winter, while chlorpyrifos, aldrin, and chlorpyrifos,
aldrin, and diazinon were not detected. In the spring season, endosulfan, heptachlor, and
aldrin were detected. Endosulfan, heptachlor, dicofol, p,p\'-DDT, aldrin, chlorpyrifos, and diazinon were detected in the autumn season. Similarly, in the summer season, endosulfan, heptachlor, dicofol, p,p\'-DDT,
aldrin, chlorpyrifos, and diazinon were detected. The sequence of estimated daily intake (EDI) in Nile tilapia during the four seasons is heptachlor > endosulfan > dicofol > p,p\'-DDT > aldrin > diazinon > chlorpyrifos. The sequence of EDI in African catfish during the four seasons is endosulfan > p,p\'-DDT > heptachlor > aldrin > dicofol > diazinon > chlorpyrifos. In conclusion, the results confirmed the absence of a hazard index for consuming Nile tilapia and African catfish collected from the Kitchener drain.
