Outdoor nitrogen dioxide exposure and longitudinal health status trajectory in the Canadian National Population Health Survey.

Few studies have examined the association between air pollution and the trajectory of global health status measures related to the functional impacts of chronic disease. To address this gap, we examined the trajectory of the Health Utilities Index (HUI) over 17 years of follow-up among Canadian National Population Health Survey (NPHS) participants. Annual average nitrogen dioxide (NO) exposures from a national land use regression surface were mapped to 15,631 NPHS participants at their place of residence provided at each follow-up.

Attribution of fine particulate matter and ozone health impacts in Canada to domestic and US emission sources.

Exposure to ambient air pollution is associated with a wide range of adverse health effects such as respiratory symptoms, cardiovascular events, and premature mortality. Canada and the United States (US) have worked collaboratively for decades to address transboundary air pollution and its impacts across their shared border. To inform transboundary air quality considerations, we conducted modelling to attribute health impacts from ambient PM and O exposure in Canada to Canadian and US emission sources.

Health impact analysis of PM from wildfire smoke in Canada (2013-2015, 2017-2018).

Smoke from wildfires contains many air pollutants of concern and epidemiological studies have identified associations between exposure to wildfire smoke PM and mortality and respiratory morbidity, and a possible association with cardiovascular morbidity. For this study, a retrospective analysis of air quality modelling was performed to quantify the exposure to wildfire-PM across the Canadian population. The model included wildfire emissions from across North America for a 5-month period from May to September (i.
