An ecological analysis of PM2.5 concentrations and lung cancer mortality rates in China.
Bottom Line: Geographically weighted regression was performed to evaluate the relation between PM2.5 concentrations and lung cancer mortality for males, females and for both sexes combined, in 2008, based on newly available long-term data.Lung cancer fatalities from long-term exposure to PM2.5 were calculated according to studies by Pope III et al and the WHO air quality guidelines (AQGs). 31 provinces in China.PM2.5 was associated with the lung cancer mortality of males, females and both sexes combined, in China, although there were exceptions in several regions, for males and females.

Mentions: Figure 4 shows the proportion of the Chinese population affected by the cumulative distribution of annual PM2.5 for 2001, 2005 and 2010; these data were obtained by overlaying the annual PM2.5 grids with the gridded population data. The proportion of the population exposed to PM2.5 concentrations of 15 µg/m3 increased from 2001 to 2005 and subsequently decreased (by approximately 50%) to levels observed in 2001 by 2010. The proportion of the population that was exposed to PM2.5 concentrations greater than 15 µg/m3 was approximately 90%, and this value changed little over the 10-year period. Thus, it is important for China to estimate the potential risk of mortality from lung cancer related to exposure to PM2.5, and to explore the relation between PM2.5 and mortality from lung cancer.
