What causes air pollution Asia?
The major sources of air pollution are transportation engines, power and heat generation, industrial processes, and the burning of solid waste.
Why is PM 2.5 harmful?
The size of particles is directly linked to their potential for causing health problems. Fine particles (PM2.5) pose the greatest health risk. These fine particles can get deep into lungs and some may even get into the bloodstream. Exposure to these particles can affect a person’s lungs and heart.
