Abstract:
In this study, Organonitrogen pesticides (ONPs) levels were determined in surface and groundwater samples from El-Rahawy area in the southwestern part of Nile Delta, Egypt. Gas Chromatography with NitrogenPhosphorous Detector (GC-NPD) was proposed to determine the concentration of eleven ONPs, molinate,atrazine, simazine, prometon, propazine, prometryn, simetryn, ametryn, alachlor, terbutryn and metolachlorduring winter and summer seasons. The most abundant components were molinate and propazine. The total concentrations of ONPs in the surface samples were from 3.9636 to 75.878 ng LG1 while in groundwater were below the detection limit i.e. 0.02 ng LG1. The results have been discussed and compared with Canadian water quality guidelines for irrigation and fresh water
