四种重金属对海洋钙质角毛藻的毒性

Toxic effect of four heavy metals on Unicellar marine algae

研究了 Ｈｇ^(２＋)、Ｃｕ^(２＋)、Ｚｎ^(２＋)、Ｃｄ^(２＋) ４种重金属，其单一及 ４种混合对海洋单胞藻钙质角毛藻Ｃｈａｅｔｏｃｅｒｏｓ ｃａｌｃｕｔｒａｎｓ毒性效应，结果表明：单一的重金属毒性强于４种重金属混合。而且，不同重金属对单胞藻的毒性效应有所不同，其毒性为Ｈｇ~２＋＞Ｃｕ~２＋＞Ｚｎ~２＋＞Ｃｄ~２＋。

The paper reports the toxic effect of four heavy metals single and mixture of all unicellular marine on Chaetoceros calcutrans (panleen) Takano, The results show that the toxicity of single heavy metal was greater than that of the mixtave of four heavy metals. And the toxicity of different heavy metal on Unicellular algae was different. The order of toxicity is Hg^(2+)>Cu^(2+)>Zn^(2+) >Cd^(2+)
