It’s hard to avoid phthalates, a group of chemicals that make plastic soft and flexible, in our daily lives. Phthalates are in so many things we use: food containers; shampoo and beauty and skin care products; building and gardening materials; faux leather fashion and furniture upholstery; medical devices; toys; backpacks and purses; and home accessories like polyvinyl chloride (PVC) shower curtains. The list goes on and on. More:

The researchers started in an alligator pond and ended up at a fertility clinic. They were looking at bodily fluids — first in large reptiles, then humans — searching for a group of environmental contaminants that even the U.S. government didn’t have a handle on, clueless still about their ubiquity and potential harm.

When interior designers spec materials for a project, they have many considerations to make, from the pretty—color, pattern, texture—to more practical considerations like durability and sustainability.

Birth defects related to chromosomal abnormalities often stem from exposure to chemicals early in the mother's life. But determining which chemicals are at fault poses a serious challenge—akin to solving a hit-and-run case, decades after the fact.

Laurie Harper, director of education for the Bug-O-Nay-Ge-Shig School, a K-12 tribal school on the Leech Lake Band Indian Reservation in northcentral Minnesota, never thought that a class of chemicals called per- and polyfluoroalkyl substances, or PFAS, would be an issue for her community.
