There are many sources of PM2.5 emissions, including road transport, industrial activities, crop burning, and energy industries. Domestic combustion, such as burning wood for fuel, is also a major source of PM2.5 emissions. As a result, PM2.5 concentrations are typically higher in developing countries. Health impacts of air pollution Exposure to high levels of PM2.5 increases the likelihood of heart and lung problems, and can lead to premature death. Air pollution is one of the leading causes of premature deaths worldwide, cutting millions of lives short every year.
