| 摘 要： | 本文反映了Hg^2 ,Cu^2 ，Cd^2 ,Cr(6)对蒙古裸腹溞（Moina mongolica Daday)的存活、生长、生殖及内禀增长率(rm)毒性的研究工作。得出这四种重金属对该溞的48hrLC50分别为0．00334、0．0888、3．89、4．24mg／l。文中还反映了这四种重金属的不同混合方式对蒙古裸腹涵生长、生殖和内禀增长率的毒性。两种金属混合后的毒性加强(Hg／Cu除外)；三种和四种金属的混合毒性低于两金属的混合毒性。

| Abstract: | The acute and chronic toxicity of mercury, copper, cadmium andchromium to the survival, growth, reproduction and the intrinsic rate of increase(r_m) of M. mongolica were studied. The 48 hr LC_(50) of Hg~(2+) Cu~(2+), Cd~(2+) andCr(6) was 0.0034, 0.0888, 3.89 and 4.24 mg/l respectively. The toxicity ofcombined different metals to the organism was also studied. The result reveals thatthe toxicity of mixtures of two metals was much stronger than the single one (ex-cept Hg/Cu). While the toxicity of three or four metals combination was lower thanthat of two metals. |
