中文摘要:
      本文反映了Hg2+,Cu2+,Cd2+,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溞生长、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。
英文摘要:
      The acute and chronic toxicity of mercury, copper, cadmium andchromium to the survival, growth, reproduction and the intrinsic rate of increase(rm) of M. mongolica were studied. The 48 hr LC50 of Hg2+ Cu2+, Cd2+ 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.
