Ambient PM<sub>2.5</sub> and PM<sub>10</sub> Exposure and Respiratory Disease Hospitalization in Kandy, Sri Lanka
Evidence of associations between exposure to ambient air pollution and health outcomes are sparse in the South Asian region due to limited air pollution exposure and quality health data. This study investigated the potential impacts of ambient particulate matter (PM) on respiratory disease hospitali...

Evidence of associations between exposure to ambient air pollution and health outcomes are sparse in the South Asian region due to limited air pollution exposure and quality health data.
