摘要
Background and Objective: Several industries release their waste water directly in to the aquatic ecosystems without appropriate treatment. The toxic heavy metals present in that waste water cause water pollution and also affect the aquatic organisms. Hence, the present work has been aimed to find out the acute toxicity of nickel, chromium and their combinations to the fingerlings of the Indian major carp, Cirrhinus mrigala. Materials and Methods: The fingerlings of C. mrigala were subjected to static bioassays to determine the acute toxicity of chromium, nickel and their combinations. Using probit analysis, 24, 48, 72 and 96 h LC50 values were determined along with 95% fiducial limits. The results were subjected to Chi-square test to find out the goodness of fit. Results: The 96 h LC50 values of chromium, nickel, Ni+Cr and Cr+Ni were 21.3, 25.8, 42.4 and 76.0 ppm, respectively. Chromium was more toxic to the fish than nickel. When all the tests are compared, Cr+Ni combination was the most toxic to the fish. Conclusion: Among the metals tested chromium were more toxic to the fish than that of nickel.

背景与目的：一些行业未经适当处理就将废水直接排放到水生生态系统中。废水中存在的有毒重金属会造成水质污染，也影响水生生物。因此，目前的工作旨在发现镍，铬及其组合对印度大鲤鱼（Cirrhinus mrigala）的鱼种的急性毒性。材料与方法：对印度rig草的鱼种进行了静态生物测定，以确定铬，镍及其组合的急性毒性。使用概率分析，确定24、48、72和96 h的LC 50值以及95％的基准限值。对结果进行卡方检验，以找出拟合优度。结果：铬，镍，Ni + Cr和Cr + Ni的96 h LC 50值分别为21.3、25.8、42.4和76.0 ppm。铬对鱼类比镍更具毒性。比较所有测试后，Cr + Ni组合对鱼的毒性最大。结论：在所测试的金属中，铬对鱼类比镍更具毒性。
