pollution sources recognition
Molecular formula :

nature : Analysis of the source added. Application of mathematical statistical methods of atmospheric particulate matter concentrations of the elements contained in data processing, analysis from the various elements of the sources and possible contribution rate. Now there are more applications enrichment factor, chemical elements in balance, factor analysis and cluster analysis. Extrapolation and discriminant particles of different sources and their relative contribution, understanding and evaluation of the degree of pollution, control sources of pollution are of important significance.
