Regression Calculating And Total Amount Control Analysis In TSP Source Apportionment

At present, atmospheric particulate pollution is very serious in China. Particulates are the chief pollution matters of atmospheric pollution in cities of China, which have been reported by the public Report of Chinese Environmental Quality in 1999-2003. It has been stated by the investigation in 2001 that only 36.3 percent of 350 cities have passed Grade two national standard, While there are 223 cities which have exceeded the National Secondary Standard, which is 63.7 percent of all investigated cities, There were 109 cities in these cities which had exceeded the National Tertiary Standard, which is 31.1 percent of all the investigated cities.To effectively control and improve atmospheric particulates pollution, qualitative or quantitative analysis of atmospheric particulates pollution is needful. It need analyze the sources of atmospheric particulates, For taking effective approaches to the particulates pollution. Scientists transfer the point of view from discharge source to receptor(a local atmospheric environment is effected by polluted source), have created receptor models, then gradually form a series of analyzing source technology, Which can determine the receptor contributive value caused by various pollution source according to chemical or microscopic analysis on atmospheric particulates sample and source sample.The article fully concludes that atmospheric particulates do harm to human being and social production. On this understanding, analyzing the development trends of Chinese urbanization and its causing to environmental problem, and bringing up the relation of-TSP producing and urbanization, the article also explains the chemical balance method adopted by China now. The chemical quality balance method are not feasible to the small and medium cities on the urbanization developing level and the economy carrying capacity. The operating method suitable for the situation of China is put forward to explain TSP source, according to the actualities of discharging atmospheric particulates and disposal instance. At first, to gain the experimental data through the chemical quality balance method, then using mathematics regression to make mathematical models, and obtaining mathematical expression which can easily resolve atmospheric particulates source. In this case, we can analys TSP sourceapportionment in small cities quantitatively. To make the technique of source apportionment applied to the engineering of environmental "quality standards in air. The aim of atmospheric particulates source apportionment is to control the total amount TSP, to analyze source intensity of various sources from acceptor space. Then, processing source intensity can ensure atmospheric particulates to meet standard for discharge of pollutants, and it will ensure better environment in Chinese city development. In every way, the engineering of controlling the total amount TSP source apportionment includes as follows: first, analyzing the origin of particulates;second, making out measures for their fulfillment of atmospheric quality meeting standard for discharge of pollutants functional district;third, evaluating and enforcing the measures. The first point is very important, so it is most necessary to create a effective and easy apportionment method.
