Dynamic variation for SO2 of Atmosphere in Beijing
SO2 is the second prime contamination of atmosphere pollution in Beijing that can enter our respiratory system and blood circulation system and hazard our body health. Government and a lot of scholars focus the SO2 pollution. To access efficiency of these control measurements, it is very necessary to confirm the SO2 concentration of Beijing atmosphere, especial for dynamic variation for the SO2 concentration of Beijing atmosphere. However, little exists on the study on dynamic variation for the SO2 concentration of Beijing atmosphere. This paper represents daily, monthly and Interannual dynamic variation of SO2 concentration of Beijing atmosphere base on reference data, Daily Report of Air Quality in Beijing, Beijing Environmental Statement and Beijing Statistic Yearbook. The main conclusions include: 1) SO2 concentration of Beijing Atmosphere in heating season is larger that in no-heating season. The former is larger the state standard; while the latter is less than the state standard. In addation, SO2 concentration of Beijing Atmosphere in heating season and no-heating season have similar characteristics. But then, SO2 concentration of Beijing Atmosphere in heating season have stronge change amplitude. 2) As a whole, during of the course heating season, SO2 API of Beijing Atmosphere will be larger ones in other times and it will be in the lowest value in July and Augest. Except for considering pollution resource, although there is some relationship between SO2 of Beijing Atmosphere with atmosphere diffusion, vegetation and rainfall have very great effect on SO2 of Beijing Atmosphere. 3) In 1981-1998, SO2 concentration of Beijing atmosphere takes on increase tendency with some fluctuation and in 1999-2006, SO2 concentration of Beijing atmosphere decreases year after year. This paper helps to provide the scientific basis for controlling the polluted air in Beijing.
