Endocrine disruptors (EDs) are a class of chemicals with the ability to interfere with the endocrine (hormonal) processes in mammals. Any hormonal process in the body can potentially be impacted by endocrine disruptors. As a result, EDs have been linked to many health-related issues, such as learning disabilities; brain and cognitive development problems; breast and other cancers; deformations of limbs; feminizing of males and masculinizing of females. Unlike toxins, the impact of EDs on health is not typically short-term, and long-term effects may be drastic.
