摘  要:
实验室条件下,在经过沉淀以及过滤的自然海水中分别加入不同浓度的Hg2+、Pb2+、Cd2+离子,分别对国产和进口2 个产地的卤虫卵进行了孵化试验。结果表明:与对照组相比,3种重金属离子都降低了2个产地卤虫卵的孵化率,且浓度越高降低的百分率越大,3种重金属离子降低孵化率大小顺序为:Hg2+>Cd2+>Pb2+;3种离子对2个产地的卤虫卵产生了不同的影响:进口卤虫大于对国产卤虫卵的降低率。

摘  要:
The different concentration of irons Hg2+,Pb2+ and Cd2+ were added into precipitated and filtrated seawater in order to observe the hatching rate of domestic and import Artemia salina eggs.The results howed that:The hatching rate of the two origin Artemia salina eggs was reduced on effect of three kinds of heavy metal irons as compared with contrast groups,the bigger concentration of iron was,the lower hatching rate was,and the order of reduction was:Hg2+>Cd2+>Pb2+;The effect of three kinds of irons on hatching rate of two origin Artemia salina eggs was:import>domestic.
