What is the Origin of Environmental Toxicology?

The term is a combination of "environmental," referring to the external surroundings, and "toxicology," derived from the Greek toxikon (poison) and logia (study of). This area of study gained clinical significance with the recognition that man-made chemicals can mimic or interfere with endogenous hormones, leading to reproductive, developmental, and metabolic dysfunction.

What is the Mechanism of Environmental Toxicology?

Environmental toxicants often exert their effects by acting as xenoestrogens or anti-androgens, binding to and modulating nuclear hormone receptors, such as the estrogen or androgen receptors. Other mechanisms involve interfering with the synthesis, transport, metabolism, or excretion of natural hormones, thereby altering circulating concentrations and disrupting feedback loops. This disruption of normal endocrine signaling can lead to adverse health outcomes by reprogramming cellular function and gene expression.

Environmental Toxicology

Meaning

Environmental toxicology is the scientific discipline that studies the harmful effects of chemical, biological, and physical agents originating from the environment on living organisms, including humans. Within the hormonal health space, this field specifically examines the impact of endocrine-disrupting chemicals (EDCs), heavy metals, and persistent organic pollutants on the body’s intricate endocrine system and metabolic pathways. It provides a framework for understanding exogenous factors that compromise internal homeostasis.
