Air Quality in Taiwan

I’m a Senior Scholar and visiting researcher who studies air pollution in the College of Public Health at National Taiwan University. My primary appointment is Professor of Civil and Environmental Engineering at Virginia Tech, where my research group applies quantitative methods to track the emissions, transformations, and fate of gases and particles in indoor and outdoor air. When people find out what I study, they often exclaim, “The air pollution is so bad in Taipei!” While vehicle exhaust along busy streets is often noticeable, in general, Taipei’s air quality is relatively good compared to that of other large cities in Asia. In fact, this is one of the reasons why my family selected Taipei for our sabbatical. How is the air quality in Taiwan?      The pollutant of greatest concern in Taiwan is fine particulate matter of diameter 2.5 microns and smaller (PM2.5); it is roughly 100 times smaller than the diameter of human hair. Exposure to elevated levels of PM2.5 can cause coughing, make it hard to breathe, and aggravate asthma. Long-term effects include cardiovascular disease, certain types of cancer, and ultimately, premature death. The World Health Organization estimates that exposure to PM2.5 is responsible for 7 million
