Monitoring and removal of pesticide residues in Drinking water collected from Kafr El-Sheikh governorate, Egypt [electronic resource].

Includes reference.

Drinking water contamination by agrochemicals particularl) pesticides is an importaDt environmental and health issue in different part of the world. Monitoring of pesticide residues was conducted at different sources of water purification plants in Kafr El-Sheikh governorate (Kafr ElSheikh, FoWl!, EI-HamouI, Mebalet Abuali and Ebshan). Furthennore, the removal of pesticide residues in drinking water by using powdered activated carbon was evaluated at both the intake and outlet ofeach water purification plant. The results showed that, aldrin, lindane, DDE, DDD, dirnethoate, methyl parathion and malathion were the detected pesticides. OrganochJonn pesticides (OCPs) detected with higher concentration than organophosphates (OPPS) at aD sampling sites. Aldrin and lindane were detected with highel- frequency and concentration level than other compounds. The concentrll,tion levels of detected pesticides were much lower in outlets than at the intake points ofwater purification plants. water treatmeot itself may reduce or remove the pesticide residues from water. The concentration leve\ ofdetected pesticides in Kafr EI-Sheikh governorate still lower than the maximum residue Iirnits (MRLs). The powdered activated carbon elfectively reduces pesticide residues in drinking water, which promise as water purification technique.
