Abstract :

In this study species samples of the most consumed fishes , Sefid , with scientific name of Rutilus FrissiKutum has been analyzed for concentraition on one of organochlorine pesticides as DDT.Sampleshave been captured on 5 staitions(Bandartorkaman, Khazarabad,Fereidunkener,Noor and Chalous)in twoprovinces in the south of caspian sea (Mazandaran and Golestan). Determination of this pesticideconcentration was performed by gas chromatography equipped with electron-capture detector(GC-ECD).Asresult ,average of DDT concentration in the samples of the whole area is about 0.0035 ppm per fat weight.Sample of chalous station has the highest concentration than the others (0.016 ppm per fat weight) and Bandartorkaman &Fereidun kener with 0.0003 ppm per fat weight have the minimum concentration.
