Abstract

More and more people have begun to realize this; people's negative impact on the environment has become more and more obvious. There are two main types of air pollution: outdoor air pollution and indoor air pollution. Particulate pollutants and other gaseous pollutants constitute outdoor air pollutants. There are many different reasons that cause indoor air pollution. If the harmful substances in indoor air exceed the limit, it will harm our health and we are prone to respiratory diseases. Formaldehyde, containing stupid substances and stupid derivatives, ammonia, radioactive radon and so on is the main components of chemical pollutants. In the past three decades, the most serious urban pollution in China has been the smog, which has become worse and worse with the worsening environment in the central and western regions.
