effect of sub-lethal diazinon concentrations on blood plasma biochemistryl

diazinon is commonly used for pest control in the agricultural fields surrounding freshwater reservoirs. this study was conducted to determine the chronic toxicity of organophosphorous pesticide and its effects on some hematological parameters and biochemical blood plasma profiles of common carp, cyprinus carpio. diazinon was applied at concentrations of 60 and 120î¼g/l preparations in 10, 20 and 30 days since the experiments were initiated. the experimental groups showed significantly lower values (p < 0.05) of erythrocyte count, haemoglobin content, haematocrit, leucocytes, lymphocyte and monocyte, as well as in alkaline phosphatases and significantly higher (p
