Associations between fine particulate matter and mortality in the 2001 Canadian Census Health and Environment Cohort

Initiatives -
The purpose of the present study is to assign exposures based on a relatively fine-scale PM2.5 model (approximately 1 km grid), which incorporated both remote sensing estimates and ground observations. Note: All published information has been collected from the article referenced in the Marker Paper box below. Therefore, there may be variations with more advanced versions of the study.

Timeline

Population

We followed 2.4 million respondents who were non-immigrants aged 25–90 years and did not reside in an institution over a 10 year period for mortality. Exposures were assigned as a 3-year mean prior to the follow-up year
