污染的有害排放物（有毒物质，化学物质和气体）通过呼吸进入人体，但这些有害物质也对土壤，植物或水的影响，最终对人类的影响。随着酸雨、温室气体等环境的严重破坏，它对人类的健康产生了不利影响。有时这些都是刺激性、头痛和恶心的急性影响，有时慢性疾病如癌症、肺、肝和神经系统的损害，出生缺陷和严重的呼吸道疾病严重危害公众。
最近，它已被观察到的PM指数达到了2.5，已经超过了安全线，这是最危险的污染物对人体健康造成不可挽回的损害中枢神经系统。根据空气质量准则发布的世界卫生组织（世卫组织）、北京等地铁城市已超过正常线。增加的水平可能会提高脑血管疾病，癌症和过早死亡的机会，因为下面的数字提到了估计死亡人数，由于污染和经济损失可能会产生的北京只。
北京政府为解决空气污染问题，在2013推出五年计划的计划中，注入8000亿元，2017的清洁环境。这些措施包括减少工厂排放量，减少煤炭的使用量，限制车辆的道路。虽然北京市环境保护局主要归咎于车辆的运行环境的恶化，声称他们生产的31.1%的2.5点，感觉已经面临来自公共部门的批评，说它是一种限制人身权利，当局正试图。

Pollution’s hazardous emissions (toxic substances, chemicals and gas) go into the human body by breathing, but these harmful substances also influence to soil, plants or water and ultimately to the human beings. Along with Environmental severe damages such as acid rains and releasing greenhouse gas, it affects the health of human adversely. Sometime these are acute effects in the form of irritation, headaches and nausea and sometime chronic diseases like cancer, lungs, liver and nervous system damages, birth defects and critical respiratory diseases severely cause harm to the public.
Recently, it has been observed that PM index has reached to 2.5 and has gone beyond the safety line and it is the most threatening pollutants to human health that causes the irretrievable nervous system damage. As per the air quality guidelines issued World Health Organization (WHO), Beijing and other metro cities have already exceeded the normal line. The increased level of PM may raise the chances of cerebrovascular diseases, cancer and premature death as the below figure mentions the estimated number of death due to pollution and the economic loss may be incurred by the Beijing only.
The Beijing government is injecting 800 billion yuan in a plan spanning five years launched in 2013 to tackle air pollution and introduce cleaner environment by 2017. The measures include reduction of factory emissions, cutting down usage of coal and restricting vehicles on the road. Although the Beijing Environmental Protection Bureau blamed mainly the operation of the vehicles for the deterioration of the environment, claiming that they produced 31.1% of all the PM 2.5, the perception has faced criticism from sections of the public, stating that it is a restriction of personal rights that the authorities are attempting.
