Urban air pollution and the necessary preventive countermeasures

SUN Xiao-li,LI Sheng-cai,ZENG Qing-xuan,FENG Chang-gen(State Key Laboratory of Explosion Science and Technology,Beijing Institute of Technology,Beijing 100081,China)  
The present paper intends to introduce the urban anti-pollution strategy from the government officials to the local people themselves and summarize the latest advancements in the research in the mechanism of actions along with the study of modeling,theorem of molecular collision and inertial separation,preparation of composite adsorbents and other methods in the urban air pollution and preventive countermeasures.It has also brought about some suggestions on how to cut down the urban air pollution based on the references provided.To reduce the harmful pollution and avoid the destruction of the environment by people themselves and establish a healthy and harmonious social environment,it is necessary to stress the improvement of natural factors so as to keep up the balance between natural factors and human interference ones.All in all,a desirable living environment calls for every one of us to work hard for its construction.To solve the above problems,we prefer to divide the sources leading to the social and natural pollution into that coming from nature and that from human interference. As to the pollution types,it can be divided into poisonous gas,particulate matters,greenhouse-effecting waste gases and others.Last of all,the paper has also summarized all the preventive countermeasures likely to be taken by the governmental or non-governmental constitutions in the future so as reduce the environment pollution.
