Atrazine's effects in humans and animals primarily involve the endocrine system. Studies suggest that atrazine is an endocrine disruptor that can cause hormone imbalance. [9] Atrazine has been found to act as an agonist of the G protein-coupled estrogen receptor 1. [28]
Tyrone B. Hayes (born July 29, 1967) is an American biologist and professor of integrative biology at the University of California, Berkeley.He is known for his research in frogs, concluding that the herbicide atrazine is an endocrine disruptor that demasculinizes male frogs, causing them to display female characteristics.
Most notably, American conspiracy theorist Alex Jones cited research on the effects of atrazine on frogs, which can induce spontaneous sex change or hermaphroditism, to claim that the U.S. government was "putting chemicals in the water that turn the friggin’ frogs gay" as part of a "chemical warfare operation" to increase homosexuality and ...

There are almost 5,000 different types of PFAS — some studied more than others — and they can accumulate in the human body over time, which "may cause serious health conditions," the U.S. Food ...
The U.S. EPA said in the 2003 Interim Reregistration Eligibility Decision, "The total or national economic impact resulting from the loss of atrazine to control grass and broadleaf weeds in corn, sorghum and sugarcane would be in excess of $2 billion per year if atrazine were unavailable to growers." In the same report, it added the "yield loss ...
Atrazine Chlorohydrolase (AtzA) is an enzyme (E.C.3.8.1.8), [1] which catalyzes the conversion of atrazine to hydroxyatrazine. Bacterial degradation determines the environmental impact and efficacy of an herbicide or pesticide. Initially, most pesticides are highly effective and show minimal bacterial degradation; however, bacteria can rapidly ...
As this study involved intra-cerebellar injections, its relevance to environmental exposures is unclear, as is the role of an estrogenic effect compared to some other toxic effect of bisphenol A. Other scientists argue that the observed effects are spurious and inconsistent, or that the quantities of the agents are too low to have any effect ...
