According to a study presented at the 70th AAN annual meeting, people with consistently high occupational exposure to diesel exhaust may have a higher risk of ALS.
Men with any diesel exhaust at jobs held for at least 10 years were 20% more likely to develop ALS than men with no exposure.
For men with a 50% likelihood of diesel exhaust exposure due to their occupation, the link was stronger ie. 45% more likely to develop ALS.
NO association was observed with women with such exposure.
