ASSESSMENT OF HEAVY METALS AND PESTICIDES CONTAMINATION OF WASTE WATER AND SOIL SAMPLES FROM DISTRICT FATEHGARH SAHIB, PUNJAB, INDIAVIKAS PAHAL, GURDYAL SINGH, MOHAMMAD DANISH AND KRISHAN SAWROOP DADHICHAbstract Unawareness among the farmers and unregulated industrialization inundated the water with harmful residues of pesticides and heavy metals salts which resulted in deterioration of quality of water in the state of Punjab, India. In the present paper, we report the quality and quantity of said pollutants in waste water and agricultural soil samples from district Fatehgarh Sahib, Punjab. HPLC analysis was carried out to analyze and quantify the concentration of pesticides (triazophos,simazine, fipronil, atrazine, carbendazim, cartap, chloropyrifos and paraquat) and heavy metals(lead, manganese, uranium, mercury, ferrous, barium and cadmium) contamination. Pesticidessimazine (0.161-0.221 ppm), fipronil (0.0338-0.068 ppm), paraquat (0.0079-0.012 ppm), chloropyrifos(0.0065-0.0089) and carbendazim (0.0076-0.0090 ppm) were observed in higher concentration in soil samples as compared to water sample. Whereas, heavy metals like lead (31-69 μg/L), manganese(112-132 μg/L), uranium (49-67 μg/L), mercury (83-113 μg/L), ferrous (55-88 μg/L), barium (24-49 μg/L) and cadmium (53-141 μg/L) were found to be more than the permissible limit in both water and soil samples. |
