二氧化氮在陽光下與空氣中的碳氫化合生化學作用,形成對流層臭氧和硝酸過氧化乙醘﹝光化學煙霧的主要成份﹞
碳氫化合物,尤其是多環性芳香化合物可致癌。
氟氯碳化物會破壞臭氧層,導致更多紫外線抵達地面,增加患癌的機會。
空氣中的煙塵使氣喘患者發作的頻率升高
使腹中胎兒出生後畸型的機率上升
生態系統:
煙塵等粒子覆蓋植物的葉片,阻礙植物吸收陽光,因此降低光合作用的效率。
二氧化硫、二氧化氮溶於空氣中的水份,形成酸雨、酸霧、酸雪,或直接溶於水體﹝湖泊、溪澗﹞,降低水土酸鹼度,使植物和水中生物死亡。
二氧化硫能直接殺死地衣。
社會:
酸雨侵蝕金屬及大理石建築、雕像,毀壞戶外文物、藝術品。
酸雨降低土壤酸鹼度,降低農產品收成。
光化學煙霧降低能見度,影響旅遊業及對空中交通造成危險。
因空氣污染而致病的人口造成醫療負擔。

The nitrogen dioxide under the sunlight with the air in carbon hydrogen chemical combination biochemistry study function, forms the troposphere ozone and the nitric acid peroxidation second grade □﹝ photochemical smog essential component ﹞
The hydrocarbon, the multi- links aromatic compound may 致癌 in particular.
The fluorine chlorine carbide can destroy the ozone layer, causes more ultraviolet rays to arrive at the ground, the increase contracts the cancer the opportunity.
In the air mist and dust causes the frequency which the asthma patient manifests suddenly to elevate
After causes in the abdomen the embryo to be born the deformity probability rise
Ecosystem:
Granule and so on mist and dust covers covers the plant the leaf blade, the hindrance plant absorption sunlight, therefore reduces the photosynthesis the efficiency.
The sulphur dioxide, the nitrogen dioxide dissolve in the air the moisture, forms the acid rain, the acid fog, the sour snow, or directly dissolves to the water body ﹝ lake, the mountain stream ﹞, reduces the water mud acid alkalinity, causes the plant and the water mesozoic death.
The sulphur dioxide can directly kill the lichen.
Society:
The acid rain corrosion metal and the marble construction, the statue, destroy the outdoors cultural relic, the artware.
The acid rain reduces the soil sour alkalinity, reduces the agricultural product crop.
The photochemical smog reduces the visibility, affects the tourism and creates the danger to the airborne transportation.
But the pathogenesis population creates the medical burden because of the air pollution.
