The widely used preservative formaldehyde, and styrene, found in food containers and coffee cups, are among eight agents added to a list of known and suspected carcinogens by the U.S. National Institutes of Health.

Formaldehyde, linked to leukemia and a rare type of nasal cancer, is “known to be a human carcinogen,” according to the congressionally mandated report published today on the health agency’s website. Styrene is categorized by researchers as “reasonably anticipated” to be cancer-causing.
