Household chemicals can harm thyroid function in young girls

A new study shows that early-life exposure to certain phthalates — a group of chemicals found in a wide variety of household items including shampoos, perfumes, nail polish, plastic toys, house building materials and more — is linked to lowered thyroid function in young girls. The new study, published in the journal Environment International looked at 229 women during pregnancy and 229 children who were three years old.
