Source apportionment of PM

Wei WEN,Shuiyuan CHENG,Lei LIU,Gang WANG,Xiaoqi WANG

Frontiers of Environmental Science & Engineering 2016, Volume 10, Issue 5, doi: 10.1007/s11783-016-0839-9

Abstract: The new hybrid approaches for the source apportionment of PM were proposed. The hybrid approach can be used for source apportionment of secondary species. The metallurgy industry was the biggest contribution source to PM of Tangshan. In winter, the contribution from the coal-fired boilers was the largest one. The objective of this paper is to propose a hybrid approach for the source apportionment of primary and secondary species of PM in the city of Tangshan. The receptor-based PMF (Positive Matrix Factorization) is integrated with the emission inventory (EI) to form the first hybrid method for the source apportionment of the primary species. The hybrid CAMx-PSAT-CP (Comprehensive Air Quality Model with Extensions – Particulate Source Apportionment Technology – Chemical Profile) approach is then proposed and used for the source apportionment of the secondary species. The PM sources identified for Tangshan included the soil dust, the metallurgical industry, power plants, coal-fired boilers, vehicles, cement production, and other sources. It is indicated that the PM pollution is a regional issue. Among all the identified sources, the metallurgy industry was the biggest contribution source to PM , followed by coal-fired boilers, vehicles and soil dust. The other-source category plays a crucial role for PM , particularly for the formation of secondary species and aerosols, and these other sources include non-specified sources such as agricultural activities, biomass combustion, residential emissions, etc. The source apportionment results could help the local authorities make sound policies and regulations to better protect the citizens from the local and regional PM pollution. The study also highlights the strength of utilizing the proposed hybrid approaches in the identification of PM sources. The techniques used in this study show considerable promise for further application to other regions as well as to identify other source categories of PM .
