A survey and measurement of residues of lindane (organochlorine pesticides) in four species of the most consumed fish in the Caspian Sea (Iran).
In this study, samples of four species of the most consumed fish (sefid, koli, kilca and kafal fish) were analysed for concentrations of lindane (organochlorine pesticides). Fish were caught using electric fishing at four sites (Chalous and Babolsar cities, Khazar Abad and Miankaleh regions) in the Mazandaran provinces of Iran. Quantitative determination of the lindane was performed by gas chromatography electron-capture detection (GC-ECD). Samples contained detectable concentrations of lindane, but at concentrations below the maximum residue limit (MRL). No differences were found in the lindane concentrations between the types of fish at each site, but there were two groups of sites that were significantly different from one another in terms of lindane concentrations: sites II-IV < site I (P <0.05). However, the concentrations of lindane residues in the muscle were found to be less than the FAO/WHO (1993) recommended permissible intake and should not be of public concern in Mazandaran province.
