SOURCE APPORTIONMENT ON FINE PARTICULATES IN ATMOSPHERE IN BEIJING

Zhang Jing, Chen Zongliang, Wang Wei(AEI,Chinese Research Academy of Environmental Sciences,Beijing 100012,China)  
Samples of suspended particles and fine particulates (2 0μm) from atmosphere were collected at five sties in Beijing from Oct.6,1992 to Jan.13,1993.After digestion,the chemical compositions and concentrations of the samples were determined by inductively coupled plasma.The source contribution of various types to fine particulates were identified using a chemical mass balance model.Results showed that in autumn,the average contributions from dust,coal burning,oil burning (automobile emission gas),and steel industry were 15 9%,28 3%,54 1%,and 1 5% respectively.In winter,the average contributions from dust,coal burning,oil burning (automobile emission gas),and steel industry were 19 2%,37 7%,42 6%,and 0 3%,respectively.
