由于汽車尾氣、工廠排放及汽油揮發(fā)等產(chǎn)生的烴類化合物在大氣中普遍存在,而大氣中多數(shù)有機物又具有一定毒性,并且在紫外光照射下,一些化合物還會與氮氧化物形成光化學(xué)煙霧,造成二次污染。因此,大氣中總烴含量,是評價環(huán)境的重要指標(biāo)。大氣中總烴分析,通常采用氣相色譜法。

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 secondary pollution. Therefore, the total hydrocarbon content in the atmosphere is an important indicator for evaluating the environment. Analysis of total hydrocarbons in the atmosphere, usually by gas chromatography.
