Air pollution nanoparticles linked to brain cancer
New research from 不良研究所 links air pollution nanoparticles to brain cancer.
Greater exposure to combustion nanoparticles produced by fuel burning could increase people鈥檚 chances of getting brain cancer according to a new study in the journal . This is the first study to suggest a relationship with the incidence of brain tumours, although previous work has shown that nanoparticles can get into the brain and that they can carry carcinogenic chemicals.
鈥淏rain cancers are rare but often fatal. When you multiply these small risks by lots of people, all of a sudden there can be lots of cases. In a large city, it could be a meaningful number,鈥� says 不良研究所鈥檚 Scott Weichenthal, who is in the Department of Epidemiology, Biostatistics and聽Occupational Health. He analyzed the medical records and pollution exposure of 1.9 million adult Canadians across the country from 1991 to 2016 in collaboration with investigators at Health Canada and Statistics Canada.
According to the researcher, combustion-related air pollutants, particularly from vehicles, are present throughout our environment and large populations are exposed to them on a regular basis. As such, regulatory actions to reduce combustion-related nanoparticles could have an important public health impact in Canada and globally.
