”Concentrations and human health risk assessment of organochlorine pesticides in edible fish species from a Rift Valley Lake – Lake Ziway, Ethiopia”

Abstract

Fish consumption is known to have several health benefits for humans. However, the accumulation of organic pollutants, like organochlorine pesticides (OCPs) could pose health hazards. Thus, OCPs in edible fish species (Tilapia, Zillii, Carp, and Catfish) from Lake Ziway, Ethiopian Rift Valley Lake were investigated to assess the potential health risks of these contaminants associated with consumption of fish. Dichlorodiphenyltrichloroethanes (DDTs), hexachlorocyclohexanes (HCHs), chlordanes, and heptachlors were observed with SOCPs concentration ranged from 1.41 to 63.8 ng g^-1 ww. DDTs were the predominant contaminants (0.9 to 61.9 ng g^-1 ww), followed by HCHs. The predominance of DDTs might be attributed to its current use in vector control and contamination from past usage. The estimated daily intakes (EDIs) of OCPs from all fish species were much lower than the acceptable daily intakes (ADIs), indicating that consumption of fish was at little risk to human health at present. However, the cancer risk estimates in the area of concern span and the hazard ratios (HRs) of HCHs, DDTs and heptachlors were exceeded the threshold value of one, indicating daily exposure to these compounds is a potential concern. This might yield a life cancer risk greater than 1 in 10⁶.
