Abstract

The mutagenicity of refuse leachate from a municipal incinerator was studied by liquid rec-assay and Ames assay. Volatile components were found to be negative, and nonvolatile components positive, in the Ames assay and the leachate was found to have DNA-damaging capacity in the liquid rec-assay with S-9 mix. PAHs derived from tobacco ash and carbonyl compounds generated by the putrefaction of foods were confirmed to be main contributors to DNA-damaging capacity and mutagenicity in refuse leachate.

摘要

采用液体复苏试验和艾姆斯试验研究了城市垃圾焚烧炉渗滤液的致突变性。在艾姆斯试验中，发现挥发性成分呈阴性，非挥发性成分呈阳性，并且在添加S-9混合物的液体复苏试验中，渗滤液具有DNA损伤能力。来源于烟草灰的多环芳烃和食物腐烂产生的羰基化合物被证实是垃圾渗滤液中DNA损伤能力和致突变性的主要贡献物。
