A Systematic Review of Organochlorinated Pesticide Residues in Caspian Sea Fishes

Abstract

Context: The worldwide production and application of pesticides, especially organochlorine in agriculture can have adverse environmental pollution and human health risks. Thus, this review evaluated and summarized the toxicological data on the existence and concentrations of organochlorine compounds in Caspian sea fish tissues. Evidence Acquisition: The data were collected from published articles in PubMed, ISI, SID, Google Scholar and so on. Results: The review showed that nine studies were recorded in databases about pesticide residues in Caspian sea fish tissues. These studies reported that there is limited evidence of organochlorinated compounds in Caspian sea fishes. All researchers detected organochlorine contaminants in examined fishes in the studied area, however DDTs was the predominant pesticides. Heptachlor, Polychlorinated Biphenyls (PCBs) and Linden were ranked next, respectively. Conclusions: In conclusion, toxicological studies showed that, although contamination level in Caspian sea fishes was relatively low, the present status might pose a risk about food chain contamination.
