Over 80% Mental Health Cases Have Been Linked To Lead Exposure, Study In Focus [Video]

Generations Impacted By Lead Poisoning

The study analysed childhood blood lead levels between 1940 and 2015, focusing on the period of peak lead gasoline usage from the mid-1960s to the mid-1970s. Here’s what researchers found:

• Generation Xers (1966–1986) were most affected, with those born between 1966 and 1970 facing the greatest mental illness burden.
• Lead exposure significantly lowered impulse control and increased neurotic tendencies in these groups.
• Populations born around 1940 and 2015 experienced the least exposure, reflecting changing environmental policies and reduced use of leaded products.

Why Lead Exposure Is Dangerous?

Lead is a neurotoxin that erodes brain cells and alters brain function. Its effects are particularly severe for children under six, whose developing brains are highly vulnerable. According to the Centres for Disease Control and Prevention (CDC), there is no safe level of lead exposure.

Even minimal amounts can cause:

• Cognitive impairments, including decreased IQ.
• Behavioural issues such as attention-deficit/hyperactivity disorder (ADHD).
• Mental health …
