The centre urged Bangkokians in risky areas to wear facemasks when leaving homes and avoid staying outdoors for extended periods. It also recommended city dwellers to reduce the use of personal cars and plant trees at home, which will serve in pollution absorption.
Major sources of PM2.5 include traffic emissions, industrial factories, forest fires, and burning of harvest leftovers.
