采用室内毒性试验研究了新型化合物吡啶锌（Zpt）对海胆（Paracentrotus lividus）和贻贝（Mytilus edulis）胚胎发育的影响。海胆胚胎的中位有效浓度（EC50）为7.7 nM，贻贝胚胎为8 nM。在0.5 nM时检测到Zpt对海胆幼虫生长的毒性作用。游艇港口中Zpt的预测环境浓度。高于预测的对海胆和贻贝胚胎无影响的浓度，表明Zpt可能对这些物种在野外暴露构成威胁。(c)2005爱思唯尔有限公司保留所有权利。
The effects of the new antifouling compound zinc pyrithione (Zpt) on the embryonic development of sea urchin (Paracentrotus lividus) and mussel (Mytilus edulis) were investigated in laboratory toxicity tests. The median effective concentrations (EC50) were 7.7 nM for sea urchin embryos and 8 nM for mussel embryos. Toxic effects of Zpt on the larval growth of the sea urchin were detected at 0.5 nM. Predicted environmental concentrations of Zpt in pleasure craft harbours. are higher than the predicted no effect concentrations for sea urchin and mussel embryos, indicating that Zpt may pose a threat to those species from exposure in the field.
