Topic: Comparative Assessment Of Organochlorine Pesticicdes Contamination In Bonga Fish Ethmalosa Fimbriata And Gladiator Swim Crab Callinectes Pallidus From Lagos Lagoon Itan-Agan And Igbo-Elejo Nigeria

Description: The study investigates the level of Organochlorine pesticides OCPs in Bonga fish Ethmalosa fimbriata and Gladiator swimming crab Callinectes pallidus of two sampling stations Itan-agan and Igbo-elejo along Lagos lagoon. Fish and shellfish were collected and extraction of pesticide residues in fish and shell fish were done according to the method developed by Therdteppitak and Yammang. The sample were then sonicated for 20min using Bransonic Ultrasound Sonicator. Fish and shellfish samples were cleaned-up using activated silica gel. The experimental samples were analysed using Gas chromatography analysis. 14 Organochlorine were found namely; Alpha HCH, Endosulfan II, Eldrin Aldehyde, Alpha chlordane, Pp DDT, Heptachlor epoxide, Gamma chlordane, Methoxychlor, Lindane, Aldrin, Endosulfan sulphate, Gamma HCH, p,p -DDE and p,p -DDD. Igbo-Elejo has high level of Aldrin 9.045 g/kg in E. fimbriata than Itan-Agan. While Igbo-Elejo has high level of Endosulfan 47.400 g/kg in C. pallidus than Itan-Agan. Itan-Agan has the lower level of pollutant than Itan-Elejo in E. fimbriata, and Itan-Agan has lower level of pollutant than Igbo-Elejo in C. pallidus. In conclusion the concentrations levels observed in the 14 organochlorines residues detected in this study were above WHO maximum permissible limits and falls below the Australian Maximum Residue Limits MRL of fifty to 1000 g/kg for fresh water fish by the Australian MRL. Indiscriminate disposal of industrial waste into the lagoon should be stopped and a proper disposal of chemicals should be invented.
