Fine particulate matter, or PM2.5, is one of the pollutants existing in the air that we breathe in every day. PM2.5 refers to fine particles that are 2.5 microns or less in diameter, or about 50 to 100 times smaller than the diameter of our hair. Therefore, when we inhale these fine particles, they can easily travel into our lung or even our bloodstream. During the dry season, PM2.5 in Bangkok and many other parts of the country reaches the hazardous level. Three years ago, a project initiated by Faculty of Engineering at Chulalongkorn University called “Sensor For All” has become one of the key players in the battle against PM2.5 in Thailand. This episode talks to Prof. Dr. Pisut Painmanakul, Department of Environmental Engineering, Faculty of Engineering at Chulalongkorn University on the PM2.5 and the Sensor For All project.
