Abstract: The airborne particulates w ere sampled from the Xigu indus trial area, the railw ay, commercial and resi- dential mixed area and Panxuan Circle road area during heating period (March, 1994)and nonheating period (August, 1994).The carbon isotopic compositions of n-alkane series of the samples were analyzed by a MAT 252 ins tru- ment (GC-C-I RM S) 、We investigated the characteristics and distributions of the carbon isotopic compositions and concluded that (1)the δ13C values in w inter resemble that in summer except that both are similar in the Xig u industial area., (2)The results, calculated using a two-end model of the carbon isotopic compositions from nC21 and nC23 show that the air pollution of the Xigu industrial area is mainly caused by oil burning, that of the urban district coal burning during a heating period and oil burning of automobile during a nonheating period, and (3) oil burning pollution matter makes up over 60 % of the organic pollution one, caused chiefly by oil burning.
