Acute Toxicity of Nickel to Five Species of Freshwater Fish
نویسنده
چکیده
Flow-through toxicity tests were conducted on common freshwater fishes: rainbow trout (Oncorhynchus mykiss), three-spined stickleback (Gasterosteus aculeatus), roach (Rutilus rutilus), perch (Perca fluviatilis) and dace (Leuciscus leuciscus), to estimate their sensitivity to acute toxicity of nickel. The 96-hour median lethal concentration (96-hour LC50) values obtained from the tests ranged from 19.3 to 61.2 mg Ni/l. According to nickel sensitivity, the species tested may be arranged in the following sensitivity order: rainbow trout > three-spined stickleback > perch = roach > dace. Obtained data could be successfully applied in solving theoretical and practical goals of aquatic toxicology.

Background: Since heavy metals can accumulate in the tissues of aquatic organisms, they can cause a range of hazardous effects which can become harmful to humans. The aim of this study was to investigate the acute effects of some heavy metals as potential dangerous substances by assessing the mortality effects of Mercuric Chloride (HgCl2), Lead Chloride (PbCl2) and Zinc Sulfate (ZnSO4) pollutan...
