Chronic exposure to fine particles (PM) and mortality: Evidence from Chile.

Unlabelled: Many Chilean cities suffer from high air pollution from industrial, mobile, and residential wood-burning sources. Several studies have linked PM air pollution exposure to higher mortality risk from cardiovascular, pulmonary, and lung cancer causes. In recent years, Chile has developed an extensive air pollution monitoring network to enforce air quality standards for PM, allowing the study of the medium-term association between PM and mortality.
