摘要：
All sources of the particulate matter less than 10 micrometers (PM10) were collected in Tangshan. Inorganic elements, water-solvent ions and carbon species of PM10 samples were investigated to identify the sources of PM10. Contribution and sharing rate of suspended dust, soil dust, coal smoke dust, construction dust, vehicles exhaust, SO42-, NO3- and sea dust to PM10 was determined based on the chemical mass balance (CMB) receptor model. The results showed that suspended dust was the most important PM10 source with a contribution of 42%; flying ash from coal combustion, particle dust from soil, vehicle exhaust were also important sources with contributions of 20%, 12% and 11%, respectively.
