His laboratory discovered that Atrazine — the world's number one selling herbicide and most common contaminant of ground and surface water — is an endocrine disruptor that both chemically castrates and feminizes amphibians. This pesticide along with others appears to have a major impact on wild amphibians and is likely an important contributor to amphibian declines. More importantly, the underlying mechanism of Atrazine's action (the decrease in testosterone and increase in estrogen production) has been identified in all vertebrate classes examined (fish, amphibians, reptiles, birds and mammals, including humans) and likely increases the risk of breast cancer and prostate problems (prostatitis and prostate cancer) in rodent models and humans.
