Abstract :
The most used QuEChERS and gas chromatography methods were performed, to evaluate the
presence of organochlorines, organophosphate, polychlorinated biphenyl and chlorobenzenes in water and in fish.
According to the standard ISO IEC 17025, a recovery rate obtained ranged from 70 to 120% assessing the
reliability of analysis results. The exceed rate in fish of Malathion is 22.2, and 5.2 ppm in sampling site XGL411
and XGL416 respectively, Endrin is 4 ppm in XGL415, Trifluralin and Parathion is 1.6, 1.4, 1.8 and 4.2 ppm in
XGL413, XGL414, XGL415 andXGL417 respectively and Pyrimiphos-Methyl is 1ppm in XGL417. In water, the
exceed rate of Trifluralin is 6.5ppb in XGL411 and Parathion and Pyrimiphos methyl is 1.1, 1.8, 1, 1, 1.5 ppb in
XGL412, XGL413,XGL414, XGL415 andXGL420 respectively. The purpose of thiswork is to assess a chemical
analysis related to screening pesticides and potentially toxic metal in water and fish samples taken from Guiers
Lake. The estimating level of contamination in fish muscles has been performed usingX-rayfluorescence technique
and the level of Cadmium have to be monitored due to the potential effects on the fish themselves and the
organism that consume them.
