An estimated 4.2 million¹ premature deaths globally are linked to ambient air pollution, mainly from heart disease, stroke, chronic obstructive pulmonary disease, lung cancer, and acute respiratory infections in children. The health risks associated with particulate matter of less than 10 and 2.5 microns in diameter (PM₁₀ and PM_2.5) are especially well documented. PM is capable of penetrating deep into lung passageways and entering the bloodstream causing cardiovascular, cerebrovascular and respiratory impacts.PM is a common proxy indicator for air pollution. It affects more people than any other pollutant.
