Organochlorine Pesticides Occurrence In Fish Muscle And Their Public Health Risks In Northwest Ethiopia
Abstract Pesticides are the parent compounds, their metabolites, and associated impurities of agricultural and health chemical inputs. If they are found concentration level higher than the standard limits, they have potential negative impacts on ecosystem in general and in fish and humans in particular. This study investigates organochlorine pesticides (OCPs) residue occurrences in fish muscle and assesses their public health potential risks, in North West Ethiopia. The concentration of OCPs residue under GC-ECD detected in 37.84% fish muscle samples. The mean amount detected were Endosalfan I, 341.50 ± 32.19 μg/kg; Endosalfan II, 36.01 ± 2.3μg/kg; Endosalfan sulfate, 5.43 ± 4.06 μg/kg; 4,4, DDE, 64.01 ± 9.08μg /kg; 4, 4, DDD, 5.65 ± 3.12μg /kg; and 4,4, DDT, 1.58 ± 0.30μg/kg. The mean concentration of Endosalfan I tested fish muscle sample was higher than that of permissible limit of different international standards. However, due to low per capital consumption rate of fish origin food in Ethiopia, health risk index (HRI) ranges from 0.002-0.1275 which shows there is no public health risk. This study highlights the possibilities of chemical residues occurrence in fish food products and hence pesticide use regulations and monitoring concentration level should be implemented regularly to avoid human and environmental health risks.
