From PM10 to PM2.5: health impacts and external costs of particulate matter pollution in Beijing China


16.03.2018 kl. 12.30 - 15.30


The control of PM10 and PM2.5 (particulate matter with an aerodynamic diameter less than or equal to 10 μm and

2.5 μm, respectively) is an environmental issue of great importance in China. Current policies in China tackle

PM2.5-10 and PM2.5 pollution through uniform pollution control measures, which results in an inefficient level of

pollution reduction from an economic perspective. Noticing the immense challenges of pollution control, this

dissertation aims to improve our knowledge of the health impacts and external costs of PM2.5 and PM10, and how

we should quantify them for effective policymaking. In this dissertation, a comprehensive comparative study of

PM10 and PM2.5 and further analysis of welfare loss caused by the pollution have been fully analyzed. This

dissertation develops a novel assessment strategy that uses sampling, geospatial pollutant, and survey data to

estimate the health impacts and external costs of PM10 and PM2.5 for pollution-control policymaking in China and

even worldwide.


There are three primary contributions of the dissertation. First of all, the dissertation constructs a well-designed

procedure to assess the health impacts and external costs of PM10 and PM2.5 for targeted policymaking. It contains

a comprehensive PM10 and PM2.5 external costs estimation strategy according to four procedures: (1) pollution

characteristic analysis, (2) integrated health risk assessment, (3) health economic loss assessment, and (4) welfare

loss evaluation (health and mood impacts). Secondly, this dissertation looks in detail at the differences between

PM10 and PM2.5 pollution, and the policy implications of these differences. Lastly, the amount of external costs due

to PM10 and PM2.5 is simulated with multiple valuation methods from different baseline levels.

Main findings of this dissertation give science-based knowledge on the avenues of effective pollution control and
