Summary
Childhood lead exposure from leaded gasoline caused 151 million additional psychiatric illnesses in the U.S. between 1940 and 2015, according to new research.
Peak exposure occurred for Generation X (1966–1986 births) due to widespread use of leaded gasoline before its 1996 ban.
The study links lead exposure to higher rates of depression, anxiety, ADHD, and altered personality traits, including increased neuroticism and reduced conscientiousness.
Lead pollution also caused a collective loss of 824 million IQ points in Americans.
I’ve said it before but I’ll say it again (along with many in this thread I’m sure): a large part of our fucked up political culture comes from lead poisoning. But not in a simple single-vector way.
I’m sitting to the obvious neurotoxin effect that lead has and the way it amplifies mental health issues, there’s another vector: the effect that the behavior of lead-poisoned individuals have on the people around them. Especially in the era of social media. And this ripples through society and creates a crescendo of sociological damage.
