Pesticides are chemicals, artificial or natural substances, used for pest control. They have negative influence on human health when accumulated in the body. Numerous studies have clearly linked pesticides exposures to various diseases including cancer and Parkinson's disease. Water bodies often serve as a key receiver of harmful pollutants emitted from industrial and domestic sources. Pesticides can often enter water through sewage plants, sewer overflows, surface water runoffs, and leaching from agricultural applications or even through improper disposal. Regulatory issues and public concerns over pesticide residues in water supplies have been increasing, and it is important to develop a reliable method for routine test of pesticides in water supplies.

520 $a Pesticides are chemicals, artificial or natural substances, used for pest control. They have negative influence on human health when accumulated in the body. Numerous studies have clearly linked pesticides exposures to various diseases including cancer and Parkinson's disease. Water bodies often serve as a key receiver of harmful pollutants emitted from industrial and domestic sources. Pesticides can often enter water through sewage plants, sewer overflows, surface water runoffs, and leaching from agricultural applications or even through improper disposal. Regulatory issues and public concerns over pesticide residues in water supplies have been increasing, and it is important to develop a reliable method for routine test of pesticides in water supplies.
520 $a Presented here is a novel solid phase extraction technique using disposable pipette extraction (DPX) followed by chromatography and mass spectrometry analysis for determination of pesticides in water. The purpose of the current study was to evaluate the suitability of high pressure liquid chromatography with UV detector (HPLC/UV), gas chromatography flame ionization detector (GC/FID), gas chromatography electron capture detector (GC/ECD) and gas chromatography mass spectrometry (GC/MS) for pesticides analysis in water. It was found that GC/FID was not suitable due to its low sensitivity and poor selectivity. GC/ECD is the most sensitive method for pesticide analysis; however, it could be affected by background components and show less specificity. GC/MS analysis using selected ion monitoring (SIM) has shown superior specificity due to good accuracy and precision when compared to GC/ECD. Therefore, GC/ECD analysis followed by GC/MS confirmation provided the necessary sensitivity and specificity for determination of pesticides in water.
