Abstract
Abstract The acute toxicity of mercuric chloride (HgCl 2 ), one of most toxic pollutants for aquatic ecosystems, in rainbow trout ( Oncorhynchus mykiss ) was investigated in the present study at three different salinities (0‰, 7.5‰ and 17‰). Actual concentration of HgCl 2 was ranged from 0.10 to 8.00 mg L -1 . The acute toxicity tests were performed by 96-h static tests in different water salinities conditions. The lethal concentrations of mercuric chloride for trout, at the end of the acute toxicity tests were evaluated by Finney’s Probit Analysis. Concentrations of HgCl 2 that killed 50% of the rainbow trout within 96 hours (96 h LC 50 ) were estimated as 0.808, 0.602, and 0.583 mg L -1 , for 0, 7.5, and 17 ppt (parts per thousand) of salinity, respectively. The sensitivity of trout to mercuric chloride was increased with increasing concentration of salinity. Key words: Water pollution, aquatic toxicology, fish, heavy metal, mercury
