Zn2＋、Cr6＋胁迫对水螅的急性毒理作用及对可溶性蛋白的影响
Effects of Zn2+ and Cr6+ Stress to Hydra Acute Toxicity and Soluble Protein
摘要
Abstract
The acute toxicity and the joint toxicity of Zn2+ and Cr6+ on Hydra (LC50 ) were stud-ied and the change of soluble protein of Hydra after stressed by Zn2+ andCr6+ wasdeterminedby the static test method .The results showed that the toxicity sequence of two heavy metals ions to Hydra was Cr6+ > Zn2+ .The LC50 of 24 ,48 ,72 and 96 h for Zn2+ to Hydra were 1.037 5 , 0.947 6 ,0.628 6 and 0.533 3 mg/L ,while for Cr6+ ,the LC50 were 0.594 7 ,0.475 0 ,0.264 7 and 0.121 4 mg/L ,respectively .The safe concentrations of Zn2+ and Cr6+ were 0 .053 3 mg/L and 0.012 1 mg/L ,respectively .The toxicity of combined Zn2+ and Cr6+ was greater than the individ-ual toxicity ,representing a result of the synergetic effect .The soluble protein content of Hydra was increased first and then decreased accompanying with the raised Zn2+ and Cr6+ concentration .关键词
