由于汽车尾气、工厂排放及汽油挥发等产生的烃类化合物在大气中普遍存在,而大气中多数有机物又具有一定毒性,并且在紫外光照射下,一些化合物还会与氮氧化物形成光化学烟雾,造成二次污染。因此,大气中总烃含量,是评价环境的重要指标。大气中总烃分析,通常采用气相色谱法。

Hydrocarbons produced by automobile exhaust, factory emissions, and gasoline volatilization are ubiquitous in the atmosphere, and most organic substances in the atmosphere are somewhat toxic, and some compounds form photochemical smog with nitrogen oxides under ultraviolet light. Cause seco
ndary pollution. Therefore, the total hydrocarbon co
ntent in the atmosphere is an im
portant indicator for e
valuating the environment. Analysis of total hydrocarbons in the atmosphere, usually by gas chromatography.
