Background Many epidemiologic studies have documented variable relationships between
ambient particulate matter (PM) and COPD hospitalizations and mortality in cities worldwide …

Background Numerous studies have reported associations between particulate matter with
aerodynamic diameters of≤ 2.5 μm (PM 2.5) and chronic obstructive pulmonary disease …

Background: Numerous studies have reported variable associations between ambient
particulate matter (PM) and chronic obstructive pulmonary disease (COPD) hospitalizations …

Background Little is known about the effect of ambient fine particulate matter (PM 2.5) on
chronic obstructive pulmonary disease (COPD) in China. The objective of this study was to …

Background Short-term exposure to outdoor fine particulate matter (particles with a median
aerodynamic diameter< 2.5 μm (PM2. 5)) air pollution has been associated with adverse …

Airborne particles have been linked to increased mortality and morbidity. As most research
has focused on fine particles (PM 2.5), the health implications of coarse particles (PM 10 …

Rationale: People with chronic obstructive pulmonary disease (COPD) have an increased
risk of cardiovascular disease and may be more susceptible to air pollution exposure …

Rationale: The associations between ambient coarse particulate matter (PM2. 5–10) and
daily mortality are not fully understood on a global scale. Objectives: To evaluate the short …

Objective The association between exposure to ambient particles with a median
aerodynamic diameter less than 10/2.5 µm (particulate matter, PM10/2.5) and COPD …

Background The linkage between ambient fine particle pollution (PM 2.5) and chronic
obstructive pulmonary disease (COPD) and the attributable risk remained largely unknown …
