Environmental chemicals interact with the normal processes occurring in human bodies in many detrimental ways. Chapter 3 discusses the basic mechanisms by which exposures to environmental chemicals perturb normal homeostasis; interfere with the communication systems that coordinate proper functioning of cells, tissues, and organs; and modify gene expression by inducing epigenetic changes. Environmental chemicals disrupt homeostasis in adults, but fetuses, infants, children, and adolescents, whose homeostatic control systems are continuing to develop, are at the greatest risk for long-term adverse health outcomes due to even brief exposures during vulnerable periods in development.
