自20世纪90年代以来，各种辅助杀菌剂越来越多地用作有机锡的替代品。然而，关于它们对热带/亚热带海洋物种的毒性的知识却严重缺乏。本研究全面研究了铜、三丁基锡（TBT）以及五种常用的强化杀菌剂（包括Irgarol、敌草隆、吡啶硫酮锌（ZnPT）、吡啶硫酮铜（CuPT）和百菌清）对12种海洋物种（其中8种是香港亚热带本地物种）生长或生存的急性毒性。我们发现 Irgarol 对自养物种生长的毒性比 TBT 更大。 CuPT 对几乎所有测试物种的毒性与 TBT 相当，但对青鳉鱼幼虫的毒性高于 TBT。由于这些杀菌剂的使用预计将在全球范围内进一步增加，因此需要对其生态风险进行准确评估，以便对其管理做出更明智的决策。这项研究为此目的提供了有用的数据集。 (C) 2011 Elsevier Ltd. 保留所有权利。
Since 1990s, various booster biocides have been increasingly used as substitutes of organotins. However, knowledge about their toxicities on tropical/sub-tropical marine species is significantly lacking. This study comprehensively investigated the acute toxicities of copper, tributyltin (TBT), and five commonly used booster biocides including Irgarol, diuron, zinc pyrithione (ZnPT), copper pyrithione (CuPT) and chlorothalonil on the growth or survival of 12 marine species in which eight of them are native species of subtropical Hong Kong. We found that Irgarol was more toxic than TBT on the growth of autotrophic species. The toxicity of CuPT was comparable to that of TBT on almost all test species, while it showed higher toxicity than TBT on medaka fish larvae. As the usage of these biocides is expected to further increase worldwide, accurate assessments of their ecological risks are required for better informed decision on their management. This study provided useful datasets for such purposes. (C) 2011 Elsevier Ltd. All rights reserved.
