中國對于污染的研討起步晚，民眾關懷以及保衛空氣質量也比較少。事實上，兒童哮喘、肺炎、心臟病以及一些其他的疾病的病發率和死亡率與PM2.5的污染水平有關。且不說PM2.5對身體的影響，就環境而言，首要對氣候產生影響。
China's research on pollution started late, the public care and air quality protection is relatively small. In fact, the incidence and mortality of childhood asthma, pneumonia, heart disease, and some other diseases are related to the level of PM2.5 pollution. Not to mention that PM2.5's effects on the body, in terms of the environment, have primary impact on the climate.
PM2.5對氣候的影響首要表現在對大氣能見度的影響。盡管顆粒物在大氣中只占很少一有些，但足以致使大氣能見度降下而困惑居民的出產日子，而對城市大氣光學性質的影響可達99%。有研討發現其致使能見度下降的首要原因有以下兩點：
The effect of PM2.5 on climate is primarily manifested in the effects of atmospheric visibility. Although particles occupy only a small fraction of the atmosphere, they are enough to cause atmospheric visibility to decrease the production of the inhabitants and affect the optical properties of the urban atmosphere by up to 99%. Some studies have found that the main reason for the decrease in visibility is the following:
PM2.5中包含著對光具有散射效應的物質
PM2.5 contains substances that have scattering effects on light
PM2.5中的硝酸鹽顆粒和硫酸鹽顆粒是致使散射效應的首要原因，入射輻射受其散射影響會反射回宇宙空間，從而使入射輻射的強度減弱。有研討結果表明散射效應與氣溶膠顆粒的質量直接有關，格外與其中所含煤煙、硫酸鹽和非土壤鉀的質量有很強有關性，其散光系數平均占總消光系數的49%。
The nitrate particles and sulfate particles in PM2.5 are the primary cause of scattering effect, and the incident radiation will be reflected back into the cosmic space by scattering, which will weaken the intensity of the incident radiation. Research results show that the scattering effect and the quality of aerosol particles is directly related to the quality, especially with containing soot, sulfates and non soil potassium has a strong sexual, the average of the total scattering coefficient of extinction coefficient of 49%.
細顆粒物中含有對光有很強吸收效應的物質
A substance that has a strong absorption effect on light
顆粒物中的黑炭致使的消光效應可以使某些當地的能見度下降一半以上，細顆粒物的吸光系數占總消光系數的27.8%。
The extinction effect of particles in the coal can make certain the local visibility dropped more than half of the total absorption coefficient of light extinction coefficient of 27.8% fine particles.
能見度的下降給咱們帶來最直接的影響即是，影響視野，簡單引起事故。當然灰蒙蒙的天空也不會給人好心境，盡管沒有直接關系，可是也不可避免地引起有些大家的郁悶心理。
The decline of visibility brings us the most direct effect, that is, affecting vision and simply causing accidents. Of course, the gray sky will not give a good mood, although there is no direct relationship, but it inevitably caused some people's depressed mentality.
