Saqib TA, Naqvi SN, Siddiqui PA, Azmi MA: Detection of pesticide residues in muscles, liver and fat of 3 species of Labeo found in Kalri and Haleji lakes. J Environ Biol. 2005 Jun;26(2 Suppl):433-8.
The pesticide residues which were detected in fish tissues are DDT, DDE, aldrin, dieldrin and deltamethrin. In total 45 samples were taken out of which 18 were found positive. Out of 18 samples DDT was found in 10 samples in small quantities. DDE was found in 12 samples in higher quantities, aldrin was found in 10 samples and dieldrin was found in 2 samples in small quantities. Deltamethrin was found in 7 samples and malathion in none. Slightly more number of residues were found in Kalri lake samples. However, quantity of pesticides was higher in Haleji lake due to polluted nature of water while number of pesticides was more in Kalri lake water, possibly due to the surrounding adjacent agricultural farms. Higher level of GPT, GOT and ALP was found in samples with higher accumulation of pesticide residues. This possibly indicates a correlation between exposure of pesticide and increased level of the 3 enzymes. |
