Environmental exposure to particulate matter and hospital admission for cardiovascular and respiratory diseases
Author: Tran Van Dinh, Le Thi Phuong Mai and Nguyen Thi Thi Tho
Summary:
Particulate matter (PM) is a complex mix of solid and liquid phase particles with a range of sizes, shapes, and chemical compositions, coming from several sources. It is the principal component of indoor and outdoor air pollution. The World Health Organization estimated that PM air pollution contributes to approximately 800,000 premature deaths each year, ranking it the 13th leading cause of mortality worldwide. Adverse effects of PM exposure on health have been reported. This work reviews the association between environmental exposure to PM and hospital admissions for cardiovascular diseases (CVD) and respiratory diseases. The results showed that while positive association between PM exposure and the hospital admission for CVD and respiratory diseases at all-age group in many studies, many studies could not find any association although the same methods were approached. Many confounding factors such as the effects of other ambient air pollutants, temperature, quality of records, and the history of the diseases might potentially affected the results of such studies resulted in the differences. Further epidemiological studies considering these confounding factors need to be conducted to better understand the association between the nature of PM’s composition and its concentrations in internal PM’s components, and CVD and respiratory diseases and hospital admission due to these diseases
