本文综述三丁基锡在海洋环境中降解的研究概况。三丁基锡的降解可分为非生物途径和生物途径,其中后者具有更为重要的意义,决定着海洋环境中三丁著锡的持久性。海洋中不少藻类、微生物和动物能够通过顺次去丁基和/或非顺次去丁基降解三丁基锡,该降解符合一级动力学方程,半衰期一般为4～19天。
This review summarizes the research progress of tributyltin in marine environment. Tributyltin degradation can be divided into non-biological and biological ways, of which the latter has a more important significance, determines the sustainability of tin in the marine environment. Many algae, microorganisms and animals in the oceans can degrade tributyltin by sequential butyl and / or non-sequential tetrabutyl reductions, which are in accordance with the first-order kinetic equation with a typical half-life of 4 to 19 days.
