Abstract

The ACUTE TOXICITY and HISTOPATHOLOGY of Kutum exposed to SEVIN was performed statically in 20±2oC. In this experiments the mean body weight of the juveniles was 2.98±0.46 g. The 96h LC50 value of SEVIN for Kutum juveniles was 3.0654 mg/l Therefore the MAC value of SEVIN in natural waters for RUTILUS FRISII KUTUM was 0.765 mg/l. According to the table of sorting the toxicity of insecticides, SEVIN was "Moderately Toxic" for caspian white fish.The clinical symptoms of caspian white fish juveniles exposed to SEVIN were consisted of abnormal swiming, losing the balance and swimming in a half circle, block of respiration movements and losining the normal color. Histopathological experiments performed on control and experimental specimens of caspian white fish with 3.1±0.23 g mean body weight after 96h exposure to SEVIN in concentration lower than LC50 96h (3 mg/l). Samples were taken from tissues of liver, kidney, gills, spleen, gut and mussels in both experimental and control groups. Sever hyperplasia, edema, inflamation and degenaratin of lamellas were observed in tissues of gills in experimental group. Also vacuolization, necrosis and multifocal hemosiderosis were seen in liver and spleen. More than this lesions, there was kidney’s tissue necrosis and enlargement of bowman’s capsule In kidney’s tissue. As the result of this research, it is concluded that HISTOPATHOLOGY of these juveniles exposed to environmental contaminants may provide useful information as to target organs and mechanism of toxic substance actions.
