The short term burden of ambient fine particulate matter on chronic obstructive pulmonary disease in Ningbo China

摘要

BackgroundNumerous studies have found associations between ambient fine particulate matter (PM2.5) and increased mortality risk. However, little evidence is available on associations between PM2.5 and years of life lost (YLL). We aimed to estimate the YLL due to chronic obstructive pulmonary disease (COPD) mortality related to ambient PM2.5 exposure.
