Abstract

The composition of the effluents from incineration plants has been studied by several authors, and some chemical compounds have been identified as hazardous to the health of the people living in the environs of such plants. On the other hand, very little is known about the chemical risks for the people working inside the incineration plants. In the present paper, an evaluation of these risks has been attempted by testing for the mutagenic activity of the extracts of airborne particulates collected inside the working area of the Municipal Incinerator of Trieste. Most samples of dust were proved to be mutagenic by the Ames test, indicating that the environment is heavily polluted with incompletely burnt materials. In fact, when a sample of settled dust was heated at high temperatures, its mutagenic activity disappeared. In addition, samples of solid residues collected at the end of the combustion process showed only weak, if any, mutagenic response.

摘要

几位作者研究了焚烧厂排出物的成分，并且已确定某些化合物对生活在这类工厂周边地区的人们的健康有害。另一方面，对于在焚烧厂内工作的人员所面临的化学风险却知之甚少。在本文中，通过检测从的里雅斯特市立焚烧厂工作区域采集的空气悬浮颗粒提取物的致突变活性，尝试对这些风险进行评估。通过埃姆斯试验证明，大多数灰尘样本具有致突变性，这表明该环境受到未完全燃烧物质的严重污染。事实上，当一份沉降灰尘样本在高温下加热时，其致突变活性消失。此外，在燃烧过程结束时收集的固体残渣样本，即便有致突变反应，也很微弱。
