Lead exposure and adult personality

Researchers surveyed over 1.5 million adults across Europe and the US to examine potential links between childhood lead exposure and adult personality traits. The study found that those with higher childhood lead levels were less agreeable and more neurotic, while those from areas with cleaner air were more conscientious.
