摘要
1. 斑马贻贝暴露在去离子水(DW，每天改变)开始在几天内死亡。超过一半的动物在一周内死亡。在接触DW之前被允许重新附着的动物比接触DW的分离动物寿命稍长，但仍然对DW的毒性作用敏感。小动物对DW的反应比大型动物更快。添加0.5 mM NaCl、0.25 mM MgSO4或少量水族水可以抑制DW的毒性作用。KCl在DW中对斑马贻贝的毒性约为水族馆水中的10倍。37 mg KCl/1 DW的毒性作用不能通过添加0.5 mM NaCl或0.25 mM MgSO4.7来阻止。DW对钾转运机制的刺激可能是DW中KCl毒性增加的原因。DW的毒性作用和DW中钾的毒性增加可能在控制斑马贻贝侵染方面有应用价值。
Effects of deionized water on viability of the zebra mussel, Dreissena polymorpha
1. Zebra mussels exposed to deionized water (DW, changed daily) begin to die within several days. More than half the animals die in DW within a week.
2. Animals allowed to reattach themselves prior to exposure to DW live somewhat longer than detached animals exposed to DW but are still sensitive to the toxic effects of DW.
3. Small animals die in response to DW faster than large animals.
4. The toxic effect of DW can be suppressed by addition of 0.5 mM NaCl, 0.25 mM MgSO4, or small amounts of aquarium water.
5. KCl is about 10 times more toxic to zebra mussels when applied in DW than when applied in aquarium water.
6. The toxic effects of 37 mg KCl/1 DW are not prevented by the addition of 0.5 mM NaCl or 0.25 mM MgSO4.
7. Stimulation of potassium transport mechanisms by DW may account for the increased toxicity of KCl in DW. Toxic effects of DW and increased toxicity of potassium in DW may have applications in controlling zebra mussel infestations.
