Particulate matter (PM) refers to small solid or
liquid particles floating in the air. These particles
can be made up of different substances like
carbon, sulphur, nitrogen and metal compounds.
Long-term ambient exposure to current ambient
PM concentrations may lead to a marked
reduction in life expectancy. The reduction in
life expectancy is primarily due to increased
cardio-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."
