二丁基锡化合物广泛用作聚氯乙烯(PVC)塑料的稳定剂。二烷基锡主要损害肝胆系统,並对神经系统亦有不良影响。有机锡T-175的化学组成为含硫醇的二丁基锡,美国已允许用有机锡T-175作稳定剂生产PVC上水管道。我国有关部门拟将有机锡T-175用于供水系统,但缺乏详细毒性资料。为此,我们对有机锡T-175的毒性进的了研究,结果报道如下。
Dibutyltin compounds are widely used as stabilizers for polyvinyl chloride (PVC) plastics. Dialkyl tin mainly damages the hepatobiliary system and also has an adverse effect on the nervous system. The chemical composition of organotin T-175 is thiol-containing dibutyltin. The United States has allowed the production of PVC sewer pipes with organotin T-175 as a stabilizer. China’s relevant departments intend to use organotin T-175 for water supply system, but the lack of detailed information on toxicity. For this reason, we have studied the toxicity of organotin T-175 and the results are reported below.
