Postdoctoral Research Fellow

Research Interests

I focus my research on environmental health. I study the characteristics and sources of ambient air pollution, focusing on PM2.5 and its chemicals. Knowing the components of PM2.5, I apply the source apportionment model to identify the contributors and their contribution quantity. At the same time, I also explore how air pollution from different sources influences human health. Although

Research

Source apportionment of PCDD/Fs in the atmosphere PCDD/Fs are highly concerned pollution because of their toxicity and persistence in the environment. Because of its stability, PCDD/Fs can be originated from the local sources or be transported through long-range transport to the monitored areas. Different tools should be used to study their origin, including profile analysis or transportation simulation model. In my research, I have found that the significant sources of PCDD/Fs in Taiwan were industrial and traffic activities, which were reduced every year. However, during some special monsoon events, the atmosphere of Taiwan could be highly impacted by air pollution from other countries.

Health impacts of PM2.5 Many research found an association between PM2.5 and human health. However, most of these researches were conducted considering PM2.5 as one type of pollutant. PM2.5 can work as a carrier that consisted of many different types of hazardous chemicals, including metals, ions, and organic compounds. It is expensive and time-intensive to analyze all the components of PM2.5. Therefore, we apply new methods using monitoring data for source apportionments. The source of PM2.5 can serve as a proxy for the features of PM2.5. We have found that with the same increment amount of PM2.5, stationary sources PM2.5 are associated with higher mortality risks than mobile sources of PM2.5.
