Abstract

The ACUTE TOXICITY and histopathology of SCHIZOTHORAX ZARUDNYI (2±0.2 g body weight) exposed to DIAZINON was assessed statically in 22±2°C, following the OECD Guideline. The 96h LC50 value of DIAZINON for the fish was 14.70 mg/l, therefore making its MAC value 1.47 mg/l in natural waters. According to the table of insecticides sorting, the toxicity of DIAZINON was low for S. zarudnyi. Some clinical symptoms and abnormal reactions such as lordosis and neural paralytic syndrome, losing the balance and swimming in a half circle, expressive pigmentation mainly on the dorsal part and block of respiration movements in the fish exposed to this pesticide were observed. Histopathological evidence from the tissues of liver, kidney, gill, and gut revealed vascular tissue of the liver, sinusoids, hepatocytes vacuole degeneration, shrinkage and degeneration of some urinary cells, dilatation of Bowman's space, pycnotic nucleus of some kidney cells and increase in the number of interstitial kidney cells. Complications, such as hyperemia, telangiectasia, edema, shrinkage, clubbing and adhesion to the secondary gill filaments were also observed.
