Researchers tracked air pollution levels between 2001 and 2016 in Toronto and Montreal and used information including mortality data and other records to follow about 1.5 million people over time and calculate the connection between the exposure to ultrafine particles and risk of death.
McGill professor breaks down how vehicle and industry pollution affect our healthScott Weichenthal is with McGill University's department of epidemiology and biostatistics, and is the principal investigator on the study that looked at the impact of air-pollution levels on mortality from 2001 to 2016.
Researchers tracked air pollution levels between 2001 and 2016 in Toronto and Montreal and used information including mortality data and other records to follow about 1.5 million people over time and calculate the connection between the exposure to UFPs and risk of death. 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, said Weichenthal, who is an assistant professor in the department of epidemiology, biostatistics and occupational health at McGill University.Fireworks aren't that bad for Montreal's air quality, new study says
"The levels in the east part of Montreal tend to be slightly higher than the west probably because there's more industrial area in the east," he said.
