Fuzzy TOPSIS Model for Pollution Assessment of Unintentional Produced Polychlorinated Biphenyls in China
Due to Chinese air concentration of polychlorinated biphenyls (PCBs) was increasingly from 2004 to 2008, and PCBs were banned in the past decade in China. With rapidly development of Chinese economy, the unintentional produced PCBs (UP-PCBs) may become the main sources of air concentration. We pay attention to investigate the production amount of different industries of different provinces in China. Through emission factor of different pollutant sources to calculate the weights, then using the fuzzy TOPSIS to assess pollutant emission, the results showed a strong and significant coefficient between cement production and emission, and between closeness coefficient (C*) and Gross Domestic Product (GDP) of different provinces in 2009, then we compare the total amount of emission to C* values in different provinces that found the order of emission assessment very approximately. Hence, the fuzzy TOPSIS methods can effectively assess the pollution emission condition of UP-PCBs.
