Chemicals are an integral part of our lives and are present in most of the products we use every day in our homes. In the bathroom for example, formaldehyde often sits in shampoo, microbeads in toothpaste, phthalates in nail polish and antimicrobials in soaps, while the medicine cabinet contains a myriad of synthetic pharmaceuticals. In the kitchen, a juicy strawberry may carry traces of up to 20 different pesticides.
