In this study samples of
four species of the most consumed fishes (Sefid, koli, kilca and kafal
fish) were analyzed for concentrations of Chlorobenzilate (organochlorine
pesticides). Fish were captured using electric fishing on four sites
(Chalous and Babolsar city and Khazar Abad and Miankaleh regions) in
Mazandaran provinces of Iran. Quantitative determination of the Chlorobenzilate
was performed by gas chromatography electron-capture detection (GC–ECD).
Samples contained detectable concentrations of Chlorobenzilate but at
concentrations below the maximum residue limit (MRL). No different found
between kinds of fishes in each sites about Chlorobenzilate concentrations
but there are two groups of sites that were significantly different
from one another in terms of Chlorobenzilate concentrations. According
to insecticides analyzed in four kinds of fishes the Kafal in the hunting
region of Khazar abad had greatest amount of 0.038 PPM. Kilca from Babolsar
had the highest amount of Chlorobenzilate, 0.035 PPM (P< 0.05). In the
case of Sefid and Koli fishes in regions, significant difference was
not seen. It is necessary to mention that no research has so far been
done to be a criterion for comparison in this area sites. However, the
concentrations of Chlorobenzilate residues in the muscle were found
to be lower than the FAO/WHO recommended permissible and should not
be public concern among peoples in Mazandaran province.
