英文摘要	The ultimate objective of abating air pollution is to protect the health and welfare of the public, while in the past, health and welfare are seldom used as the direct policy target. Often, emissions or concentrations are used as the direct target. In this paper, we put heavy weight on the justification of using a risk-based approach to address air pollution problems, and use a case study to demonstrate its technical feasibility in a Chinese setting. In the case, we study the health risks associated with SO2 emissions from the different sectors in Beijing and its surrounding areas (the Beijing-Tianjin-Hebei region), to inform control responsibility assignment and control option design. The emission inventory was classified by sectors according to Chinese Standard Industrial Classification of All Economic Activities. The Community Multi-scale Air Quality (CMAQ) modeling system is used to simulate the fate and transport of SO2 in the study region. Intake fraction, which is defined as the incremental intake per unit of pollutant released from a source or a category of sources, is borrowed to indicate the marginal risk posed by SO2 from the major sectors. The results show that the intake fraction avoided per unit of SO2 emissions abated from the four major sectors (power sector, smelting and pressing of ferrous metals, manufacture of non-metallic mineral products, and chemical industry) varies greatly, which implies that using a risk-based approach has the potential to help improve the efficiency in resource utilization for assigning pollutant control responsibilities and prioritizing pollutant control options.
