Abstract:It is difficult for chemical mass balance model to obtain the apportion coefficient of mixed atmospheric particulate source directly when mixed source and single sources are seriously collinear, so a new method, exploring origin of mixed source (EOMS), was proposed. The new model (EOMS), improved-souce-appointment technique (ISA) and method amending of ISA (MAISA) were used in source apportionment of atmospheric for a city respectively. The computational results showed that the contribution rate of dust was 28.75% according to EOMS model’s calculation, which was lower than 46.3% and 38.38% according to ISA model’s and MAISA model’s calculation respectively, at the same time, the ratio of calculated data and measured data of receptor elements based on EOMS model was closer to 1 than that base on MAISA model.
