Effects and risks of endocrine disrupting chemicals

Endocrine-disrupting chemicals (EDCs) are synthetic or naturally occurring substances that interfere with the body's hormonal signaling, and compounds like bisphenol A and phthalates—found in plastics, food packaging, and personal care products—have become ubiquitous in human environments and tissues. Research in this area examines how even low-level or intermittent exposure to these chemicals can alter reproductive development, metabolic function, and multigenerational health outcomes, often at doses well below those traditionally used in regulatory toxicology. A central challenge is establishing causality in human populations, where exposure is chronic, mixtures are complex, and effects may emerge decades after contact or manifest in offspring rather than the exposed individual. Active work is focused on refining toxicity testing methods to capture non-monotonic dose responses and hormonal crosstalk, and on identifying which life stages—fetal development in particular—carry the greatest vulnerability to lasting harm.
