Thirty remodeled “green” public housing units in Boston were each found to have at least one toxic chemical — including concentrations of formaldehyde that exceeded the U.S. Environmental Protection Agency’s cancer-based screening level — in the air both before and after renovation, according to a new study by Silent Spring Institute and Harvard T.H.

The study was published online Sept. 12, 2017, in the journal Environment International.
