大气污染基本上是复合污染。例如在汽车排气中有多种碳氢化合物可侵入肺内;有的以原来的形式,有的与其他物质起化学反应或物理吸附后变为其他型物质侵入。这些物质由于其化学成分和物理性状不同,在呼吸道内的作用点也不一样。因此,其影响或所引起的反应比较复杂,应对各种污染物质的特异作用和其作用原理进行研究。一、终末呼吸道和大气污染物质
Air pollution is basically compound pollution. For example, in car exhaust, there are many kinds of hydrocarbons that can invade into the lungs; some are invaded by other substances in the original form, some react with other substances or physically adsorb them. Because of their chemical composition and physical properties of these substances in different points of the respiratory tract is not the same. Therefore, the impact or the reaction caused by it is more complicated, and it is necessary to study the specific effects of various pollutants and their action principle. First, the terminal respiratory and air pollutants
