A new report suggests that Canadians who live in areas with higher air pollution have an increased risk of dying from conditions like diabetes and heart disease. Surprisingly, researchers did not find any increased risk of dying from respiratory disease. They said they could not explain the findings.
The study is the first to show risk estimates associated with the combined exposure to multiple pollutants, such as ozone, nitrogen dioxide and find particles. It used information from the long-form census taken in 1991 and tracked 15 per cent of the Canadian population for 16 years. Results were published in Environmental Health Perspectives. The data shows the risk of dying is about eight per cent higher in places with average levels of pollution than in places with low levels.
Researchers said air pollution is just one of many risk factors that can affect life expectancy. For example, while urban areas have higher levels of pollution, there are health benefits if people can walk to their destinations.
