Abstract
The current study aimed to evaluate the efficiency of different remediation technologies (advanced oxidation processes and bioremediation) for the removal of some insecticides (dimethoate, methomyl and lindane) in aqueous media. Furthermore, to confirm the total detoxification of selected insecticides from aqueous media after remediation using toxicity test. Moreover, to design a simple and effective remediation unit for water treatment. The results showed that, the chemical remediation with ZnO(s)/H2O2/UV, TiO2(s)/H2O2/UV and ZnO(thin film)/H2O2/UV systems gave the highest degradation rate of dimethoate followed methomyl and lindane, respectively in aqueous media. Xanthomonas campestris pv. Translucens and Aspergillus fumigatus isolates showed high potential in the degradation of the tested insecticides. There were no significant differences in enzymes activity and histopathology of kidney and liver in the rats treated with water samples after remediation relative to control treatment. Advanced oxidation processes and bioremediation are considered effective and safe methods for removal of these insecticide residues in water.
