摘要：

This study monitored the presence of organochlorines in drinking water in Kafr-El-Sheikh, Ebshan, Elhamoul, Mehalt Aboali, Fowa, Balteem, and Metobess in the Kafr-El-Sheikh Governorate, Egypt, to evaluate the efficiencies of different remediation techniques (advanced oxidation processes [AOPs] and bioremediation) for removing the most frequently detected compound (i.e., lindane) in drinking water. The results showed the presence of several organochlorine residues at all water sampling sites. Lindane was detected with high frequency relative to other detected organochlorines in water. Nano photo-Fenton-like reagent was the most effective treatment for lindane removal in drinking water. Bioremediation of lindane by effective microorganisms removed 100% of the initial concentration of lindane after 23 days of treatment. The study found that there is no remaining toxicity of lindane-contaminated water after remediation on treated rats relative to the control with respect to histopathological changes in the liver and kidneys. Therefore, AOPs, particularly those with nanomaterials and bioremediation, can be regarded as safe and effective remediation technologies for lindane in water.
