应用濒海陆基水池中8个围隔生冬系实验袋研究污染物对浮游动物的影响,结果表明:低浓度Cd,Cu,Pb,Zn,Hg的混合物对草食性桡足类的生长发育有一定的抑制作用,当浓度增到高值,抑制作用更为强烈。低浓度沉积物对草食性桡足类的生长发育同样具有一定的抑制作用,当浓度增到高值,抑制作用也更为明显,两类污染物均在不同程度上改变了生态系的结构,肉食性桡足类对污染物的反应并不明显,但幼形类住囊虫(Oikipleura sp.)对低,高浓度混合重金属则较为敏感,而对低、高浓度的沉积物却没有表现出明显的反应迹象。
The effects of pollutants on zooplankton were studied using 8 walled winter-derived experimental bags in coastal sea-based water basins. The results showed that the growth and development of herbivore copepods were affected by the concentrations of Cd, Cu, Pb, Zn and Hg Certain inhibitory effect, when the concentration increased to high value, inhibitory effect is more intense. Low concentrations of sediment on the growth and development of herbivore copepods also have some inhibitory effect, when the concentration increased to high values, the inhibitory effect is more obvious, both types of pollutants in varying degrees to change the structure of the ecosystem, The responses of carnivorous copepods to pollutants were not significant, but Oikipleura sp. Was sensitive to low and high concentrations of mixed heavy metals but not to low and high concentrations of sediments Obvious signs of reaction.
