Abstract

We have investigated the mutagenic activity of extracts from the wastewater of sewage treatment plants in municipal waste incinerators and evaluated the relative contribution of various routes of emission from the incinerator to the total output of mutagens. The mutagenicity of wastewater extracts from a complete combustion incinerator was 10% of that from an incomplete combustion unit. About 90% of all the mutagens produced in a municipal incinerator are discharged into the atmosphere as emission gases, and 10% are disposed of in the wastewater treatment plants. Most of the mutagens in wastewater treatment plants are not decomposed by normal aeration times, but are removed by adsorption onto suspended solids.

摘要

我们研究了城市垃圾焚烧厂污水处理厂废水中提取物的致突变活性，并评估了焚烧厂各种排放途径对诱变剂总输出量的相对贡献。完全燃烧焚烧厂废水提取物的致突变性是不完全燃烧装置废水提取物致突变性的10%。城市焚烧厂产生的所有诱变剂中，约90%作为排放气体排放到大气中，10%在污水处理厂中处理。污水处理厂中的大多数诱变剂不会在正常曝气时间内分解，而是通过吸附到悬浮固体上而被去除。
