It can also be found in the pipes of your home, in the toys strewn across your living room, and even in the makeup you use. Consistent exposure to lead can cause it to build up in your body. No level of exposure to lead is considered safe, and this is especially true for young children.

EDCs may be lurking in several products throughout your home, and something as seemingly harmless as a child's toy may contain these chemicals. It's not just found in plastic though – EDCs can be lurking in your carpet, cosmetics, and even some foods and drinks. Exposure to EDCs interferes with your hormones, which make up a part of your endocrine system.
