Chlorpyrifos, an organophosphate pesticide is extensively used in agriculture and thus its residues are found in soil as well as water and in the surrounding areas. The presence of these insecticides in the environment result as a significant source of ecological contamination, biomagnification and toxicity. Ten samples of soil and water were collected from the different areas like river, pond, agriculture field etc. and this samples were spiked with Chlorpyrifos to estimate the degradation of pesticides with time and pesticide is extracted by two different methods i.e solvent and Microwave assisted extraction and then Thin layer chromatography ( TLC) and Gas chromatography (GC) were used to determine the extracted Chlorpyrifos residue. The study clearly shows that chlorpyrifos residues are found in Noida & Greater Noida soil and water samples. Degradation studies showed clearly that even after 12 days Chlorpyrifos is not completely degraded in soil and converted into its hydrolytic product 3,5,6-Trichloro-2-Pyridinol and the final degradation of Chlorpyrifos was 99 -100%. Thus, the presence and degradation of chlorpyrifos residues varies with the source and time period after spray. From this data it is concluded that chlorpyrifos is a pesticide used in the Noida region and the gas chromatography gives more clear results because it detects even small amount of pesticide residue but for Thin layer chromatography higher concentration of pesticide is required.
