A new study suggests that long-term exposure to sulfur dioxide (SO2), a major pollutant from burning fossil fuels, may increase the risk of developing amyotrophic lateral sclerosis (ALS).
Researchers at the University of Quebec in Canada examined data from 304 people with ALS and more than 1,200 healthy people and found that those with the disease lived in areas with higher exposure to this pollutant.
What is worrying is that this association was observed even in areas with clean air quality that meets current standards.
These findings, which do not yet prove a cause-and-effect relationship, suggest the need to revise air quality standards to protect neurological health
