We found that people, especially who are living in areas with higher levels of these particles, have a higher risk of mortality overall as well as mortality from respiratory and cardiovascular causes," Scott Weichenthal, the study's lead investigator.
The tiny size of the particles allows them to penetrate deep into the human body and enter the bloodstream, contributing to heart and lung diseases, as well as some forms of cancer," Scott Weichenthal.
According to his analysis, areas in Montreal and Toronto located near highways, airports, and rail yards anywhere fossil fuels and organic material are burned on a large scale have higher concentrations of UFPs, meaning people who live in those areas are at a higher risk.
