Air Pollution

Air pollution by suspended particulate matter (SPM) has attracted much interest, as recent epidemiological studies have shown a strong association between suspended particulate matter concentration in ambient air and effects on human airways and mortality. The most important size fractions causing health effects are that of thoracic particles, (aerodynamic diameter < 10 µ, PM10). Epidemiologists describe the regional distribution of pollution in specific areas and compare it with the population which resides in this defined area (urban cities, rural, etc.) Measuring air pollutants is expensive and funds do not allow a large number of monitoring stations to be established.Recent epidemiological studies have shown that suspended particulate matter (SPM) in air includes SPM with median aerodynamic diameter 10 µ and below (PM10), considerably influences respiratory health. Associations between suspended particulate matter and long function parameters respiratory symptoms and mortality have been found has investigated the relationships between prevalence and chronic lung disease and long term exposure to ambient air pollution
