More than 50 new environmental chemicals detected in people

Researchers have detected more than 50 new environmental chemicals lurking in people’s bodies, the vast majority of which are little known or unknown compounds. The findings are concerning given that very little is known about these chemicals and their potential health effects.

Of these newly detected chemicals, two were perfluoroalkyl and polyfluoroalkyl substances, or PFAS. These chemicals, used in consumer products such as nonstick cookware and pizza boxes, stay in the human body for a long time and can accumulate, according to the Environmental Protection Agency (EPA). Ten of the newly detected substances were plasticizers, or chemicals used in the production of plastics. For example, one of the detected plasticizers, a group of chemicals called phthalates, are often found in fast-food packaging and have been associated with adverse health effects. Two of the newly detected chemicals are used in cosmetics; one in pesticides. But most — 37 — of these newly detected chemicals are ones that researchers have little to no information on.
