Claim summary · not a verbatim quotation
Atrazine in drinking water causes sex changes in frogs and impacts human hormone health.
The finding
What the evidence shows
The frog half has real research behind it. Tyrone Hayes at Berkeley found atrazine chemically castrated three quarters of exposed male frogs and turned some into functional females, at concentrations well under the EPA's 3 parts per billion drinking water limit. The human hormone half is where it outruns the evidence. That link is still uncertain, and the EPA has kept atrazine registered while Europe banned it in 2003.
