The main objective of the present study was to investigate the sensitivity of freshwater fish Cyprinus carpio to some heavy metals in the toxicity test programs. Fish were exposed to the wide range of mercury chloride, lead chloride and zinc sulphate with expose of metal salts in water. The acute toxicity of mercury chloride (Hg), lead chloride (Pb) and zinc sulphate were evaluated by static bioassays and calculation of the LC50 (lethality concentration for 50%). The LC50 of mercury chloride was found to be higher than other species, while lead chloride had the lowest one. The 96h LC50 were 0.93 ± 0.71, 58.0 ± 0.28 and 41.1 ± 0.20 ppm for the Hg, Pb and Zn respectively
