Abstract

The emission of mutagens from various combustion sources was compared. Flue gas samples from power plants and boilers burning coal, oil and wood were studied. Little or no mutagenic activity was observed in samples from big boilers operated under optimal conditions. The mutagenic activity of emission samples from different boiler systems burning the same fuel varied considerably. This variation was larger than the difference obtained from boilers of comparable size utilizing different fuels. The highest mutagenic activity was observed in samples from a small coal combustion unit, utilizing the fluidized-bed technique. In this case the activity was highest without metabolic activation. Extracts from all samples contained toxic compounds that, in high doses, inhibited mutagenicity.

摘要

对来自各种燃烧源的诱变剂排放进行了比较。研究了燃煤、燃油和燃木的发电厂及锅炉的烟道气样本。在最佳条件下运行的大型锅炉的样本中，几乎未观察到诱变活性或根本没有诱变活性。燃烧相同燃料的不同锅炉系统排放样本的诱变活性差异很大。这种差异大于使用不同燃料的同等规模锅炉之间的差异。在采用流化床技术的小型煤炭燃烧装置的样本中观察到最高的诱变活性。在这种情况下，无需代谢活化，活性就最高。所有样本的提取物都含有有毒化合物，高剂量时会抑制诱变作用。
