Recently public concerns about the endocrine disrupting chemicals (EDC) have resulted in the increased legistrative and regulatory attentions in many countries. Endocrine disrupter is an exogeneous chemical interfering the synthesis, transport binding, action or elimination of natural hormones in the body, which are responsible for the maintenance of homeostasis, reproduction, development and/or behavior. Reported possible harmful effects on human and animal lives, possible developmental anomalities, reproductive malfunctions and behaviors, and the ways of EDC accumulation in animal kingdom are reviewed. The current scientific papers and knowledges on the global contamination of EDCs demonstrates the conclusive data that EDCs have the potentials to cause the calamitous extermination of human and animal species by the global contamination.
