空气污染源

空气污染源 5大空气污染源中东部地区持续雾霾天气让很多人都开始关注空气污染这个话题。但是光是关心可没有用，若想要解决问题，我们先要知道空气污染的源头是什么。下面小编就来细数造成空气污染的5大污染源：
1. Power Generation
发电污染
Siting fossil fuel power stations in mainly rural areas and distributing the pollution produced more evenly via tall chimneys has resulted in improved urban air quality, though they still remain a major source of pollution, mainly sulphur dioxide and nitrogen oxides.
将化石燃料发电站建在郊区，造高烟囱让污染物更平均地分布在各处，这些当然能让城市的空气变得更好。不过，发电依旧是一个很大的污染源，主要的污染物是二氧化硫和一氧化氮。
Better dispersion of pollutants emitted by tall chimneys leads to better dilution in the air and thus lower local concentrations of pollutants. This has however led to pollution being dispersed more widely and to transboundary air pollution.
高的烟囱能够让污染物在空气中散布得更均匀，可以更好地稀释污染物，让污染物的浓度降低。然而，这却致使污染物分布得更广泛，并且会使空气污染向其他区域传播。
2. Other Industry and waste disposal
其他工业和废物污染源
Although fossil fuel power plants are the major source of industrial air pollution in many countries, all industry and many businesses, large and small, can be significant local sources of a wide range of air pollutants.
虽然化石燃料发电站是很多国家最主要的工业造成的空气污染，但是所有工业以及其他很多行业，无论大小，都有可能成为当地各种类型空气污染的源头。
All waste has the potential to affect the environment adversely by contaminating the air, soil or water. Poorly managed waste disposal sites landfill or incineration can also pose a danger to public health, through all these routes.
所有的废弃物都有可能对环境产生不利影响，污染空气、土壤和水质。如果不对废物处理处 垃圾填埋场或焚烧厂善加处理，这些废物也有可能通过各种途径对公众的健康造成影响。
