Pol­lu­tion and the brain

The Guardian Weekly - - Spotlight -

A ma­jor 2018 study found that air pol­lu­tion causes a “huge” re­duc­tion in in­tel­li­gence. For the worst af­fected cat­e­gory, older men, the dam­age is equiv­a­lent to hav­ing spent fewer years in ed­u­ca­tion. The av­er­age dam­age across men and women of all ages was one lost year of learn­ing. Re­search also links air pol­lu­tion to men­tal ill­ness. Re­search in Lon­don found peo­ple over 50 in ar­eas with high ni­tro­gen diox­ide pol­lu­tion had a 40% greater risk of de­vel­op­ing de­men­tia.
