Abstract
采用静水、充气和恒温法研究Cu2+、Hg2+、Cd2+和zn2+4种重金属离子对麦穗鱼的急性毒性作用。试验结果表明:Cu2+、Hg2+、Cd2+和zn2+4种重金属离子对麦穗鱼24 H的半致死浓度(lC50)依次为0.283、0.30、16.2、23.65 Mg/l,96 H的lC50依次为0.147、0.244、5.17、14.08 Mg/l;4种重金属离子的毒性大小顺序依次为Cu2+>Hg2+>Cd2+>zn2+,Cu2+和Hg2+对麦穗鱼的毒性较强,Cd2+和zn2+的毒性相对较弱,其安全质量浓度依次为0.001 47、0.002 44、0.051 7、0.148 Mg/l;麦穗鱼对Hg2+和Cd2+耐受力超过国家规定的淡水养殖水质标准5--10倍;麦穗鱼对Cu2+比较敏感,忍受能力比国家淡水养殖标准还低。山东省高等学校优秀青年教师国内访问学者项目经费资
