Abstract: Pesticides are compounds used by human beings especially farmers for controlling biotical factors for a long time and can bring a lot of environmental problems. Among these compounds organochlorine insecticide sprays have high half-life, the property of maintaining for a long time and high lipophilicity characteristic due to having chronic consequences that result from consuming of this compound. It is necessary to evaluate and analyse in environment especially in foods as well in fishes which have high fat and can carry this kind of insecticide. So we have investigated the remains of chlorideorgano insecticide sprays such as chlorobenzilate in the four most-consumed kinds of fish in the Caspian sea. In this investigation we have chosen four different kinds of fish, which arc highly used and available in the Caspian sea (sefid, koli, kilca and kafal). We selected 100 samples of fish from four different hunting regions (Noushahr port and three cities: Babolsar, Mahmoud Abad and Ramsar) in 2006. After cleaning, we prepared Hun muscle of the samples and after the process of extraction, we distilled them in vacuum by means of organic solvent. At last we evaluated the remains and reported based on PPM by Gas Chromatography (GC) with ECD detector. The results of insecticides analyzed in four kinds of fish showed that kafal in the hunting region of Mahmoud Abad had highest amount of 0.032 PPM. Kilca from Noushahr port had the highest amount of chlorobenzilate, 0.028 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, but, fortunately the amount of the insecticide sprays has not reached to standard level in fishes, and it raises an alarm bell.
