Total suspended participates (TSP) and their chemical composition in Beijing-TJanjin Area have been analyzed. There were 12 elements (Cd, Cu, K, Mn, Pb, Zn, Fe, Na, Ni, Cr, Sr, Ba), 5 kinds of ions (F, Cl, NO, SO, NH) and 26 kinds of organic pollutants in the regional distribution. The sources of TSP were estimated by means of orgenic odd/even carbon number rates. Atmospheric pollution affected mutually among Beijing, Tianjin, Lanfang anf Gixian County were studied with identification analysis of inorganic elements.
