Scientists from McGill University in Montreal, Canada, have conducted a new study that found that the risk of a brain tumor rises as it moves from living near a quiet street to another busy street.
The study followed medical records of 2 million people between 1991 and 2016 and was compared with the average daily exposure of nanoparticles for three years, taking into account other risk factors such as smoking.
Scientists investigated the effects of very fine particles and fine pollutants emitted mainly from road traffic and coal burning. The data showed that the risk of brain tumor increased by 10% due to exposure to 10,000 / cc of nanoparticles (UFP: Ultrafine particles) every day.
The scientists said that this rate will lead to a new case of brain cancer every three years for every 100,000 people.
The recent study linked exposure to small pollutants with brain cancer, but called for more studies, according to lead author Dr. Scott Witchenthal.
