This paper surveys
"Pollution level or Division of a dozen years ago"
This paper surveys: heavy fog in Beijing for several days, the community felt that air quality is poor, what kind of relationship between air pollution and fog?
Du Shaozhong: fog is not pollution, except that it and pollutant combination at a time, before it would have an impact on air quality. Especially during autumn and winter seasons, prone to static, such as wind, temperature inversion against the pollutant dispersion of meteorological conditions so that when the fog appears, are easier to create an air pollution. Fog causes the easy diffusion of pollutants, contaminants will also extend the mist of time.
Just past the fog, the air quality in three Yi、Sanji second stay for several days, didn't become grade four or five levels of pollution, which shows the past few years, emissions levels falling.
We are also not out of the live at the mercy of the elements of the passive situation, but also to continue its efforts to increase the intensity of emissions, coal-burning pollution reduction, motor vehicle pollution, dust pollution and industrial pollution. This requires successful government organizations, and also the wider public. Now the progress made, and would like to thank the efforts of the people.
This paper surveys over the Internet, many Web users question the monitoring results for slightly polluted haze but released all over, is the different monitoring tools, or standard different?
