From pesticides to flame retardants to components of plastics–both synthetic and natural chemicals provide many of the essential substances that improve our everyday lives. However, it is also important to make sure we consider the effects some of these chemicals may have on human health. Endocrine disruptors is a term used to describe chemicals which interfere with the normal function of our endocrine system–the collection of glands in our body that secrete hormones. The science of many of these chemicals is not quite clear as much of the work has been done with rodents only or at doses not commonly encountered in everyday life. While endocrine disruptors are not a traditional epigenetics topic, the Epigenetics Literacy Project has decided to cover these chemicals because many have tried to link endocrine disruptor effects to epigenetic changes.
