چکیده    Sublethal toxicity effects of diazinon on the structureof some organs of great sturgeon (huso huso)were investigated. diazinon was applied at a sublethalconcentration of 1.5 mg l-1 at 22±1 ºc fornine weeks as a constant bath. tissues of liver,kidney and gills were sampled and examined histopathologicallyafter 1, 14, 28, 42 and 63 days postexposure to the toxicant. the results of light microscopicexaminations of tissues revealed congestionof blood vessels, pyknosis and cloudy swelling inhepatocytes. congestion of blood vessels and thickeningof the basal membrane of bowman capsule inglumerol of the kidney were also observed. the gillof fish exposed to toxicant also showed congestionand dilation of blood vessels, swelling of the basementmembrane, hyperplasia, fusion and necrosis oflamellae. this data showed that a long term exposureof fish to diazinon can cause several pathologicalchanges in respiratory organ, haematopoietictissues and liver.
