摘要：

Pesticide industrial wastewater samples were taken from the Chinhat industrial area nearby Lucknow city, India. GC-MS analysis revealed the presence of pesticides lindane, alpha-endosulfan, beta-endosulfan, chlorpyriphos, monocrotophos, dimethoate and malathion. A pesticide mixture and wastewater extracts were studied to determine the mutagenicity by Ames Salmonella test, survival of DNA repair defective E. coli K-12 mutants and bacteriophage x systems. Wastewater samples were concentrated with XAD-resins as an adsorbent and liquid-liquid extraction procedure. The XAD concentrated sample exhibited maximum mutagenic activity in comparison to liquid-liquid extracted sample. TA98 strain was the most responsive strain for both test samples with (+S9) and without (-S9) metabolic activation, while other strains exhibited weak response. A significant decline of DNA repair defective E. coli K-12 mutants, bacteriophage x was observed with test samples in the survival. The intracellular damage was highest when treated with XAD concentrated sample as compared to liquid-liquid extract after 6h treatment. (C) 2013 Elsevier B.V. All rights reserved.
