"An Analysis of Particulate Matter of the Size 2.5 Microns and Public Health in Mae Hong Son, Thailand and a Review of Air Quality Legislation"

Air quality has presented itself as a major global issue over the course of the last several decades. Global-scale practices such as seasonal crop burnings release large amounts of particulate matter of the size 2.5 microns or less (PM2.5) into the surface atmosphere, causing air quality levels to plummet. As a result, air quality is considered to be hazardous and even toxic during certain times of the year in Southeast Asia. In this study, relationships between seasonal crop burning practices and air quality were investigated for the province and surroundings of Mae Hong Son, Thailand. Four years of monthly air quality data (February-April) were statistically analyzed for long-term trends. Air quality relationships with respiratory illnesses and mortality rates were additionally explored. Lastly, the potential role of recent air quality policy for realization of public health goals is explored for Mae Hong Son.
