Particulate matter can have detrimental effects on both our health and environment. how does particle pollution directly affect the health of humans?

Long-term exposure to current ambient PM concentrations may lead to a marked reduction in life expectancy. The reduction in life expectancy is primarily due to increasedcardio-pulmonary and lung cancer mortality.

Increases are likely in lower respiratory symptoms and reduced lung function in children, and chronic obstructive pulmonary disease and reduced lung function in adults. Hope this helped=)
