Sri Lanka’s PM2.5 Air Pollution
#117 of 192 in the PM2.5 Air Pollution progress rankings
PM2.5 air pollution, mean annual exposure (micrograms per cubic meter) represents the population-weighted exposure to fine particulate matter less than 2.5 microns in diameter, capable of penetrating deep into the respiratory tract and causing health damage (lower is better).
