前言沥青烟就是沥青加热或含沥青的物质燃烧产生的气溶胶和蒸气。沥青烟中的挥发物排放到大气中,便成为大气污染物之一。沥青烟组分极为复杂,随沥青来源不同而异,既有沥青挥发组分凝结成的固体和液体微粒,又有蒸气状态的有机物等。沥青烟气一般夹杂着一定浓度的烟尘,呈棕褐色或黑色,有强烈的刺激性气味。据报道,含6个碳原子以上的化合物,对皮肤和呼吸系统有致癌作用。经研究和动物实验证实,从煤焦油、沥青和有机溶 Asphalt fumes are aerosols and vapors produced by the heating of bitumen or the bitumen-containing material. Asphalt smoke emissions to the atmosphere, it has become one of air pollutants. Asphalt fumes are extremely complex components that vary with the source of the bitumen. Both solid and liquid particulates, as vapor components of the bituminous mixture, condense into vapors and organic matter. Asphalt fumes generally mixed with a certain concentration of smoke, was brown or black, with a strong pungent odor. It is reported that compounds containing more than 6 carbon atoms have carcinogenic effects on the skin and respiratory system. After research and animal experiments confirmed that from coal tar, asphalt and organic soluble
