From the New York Times (italics mine):
The problem is that flame retardants don’t seem to stay in foam. High concentrations have been found in the bodies of creatures as geographically diverse as salmon, peregrine falcons, cats, whales, polar bears and Tasmanian devils. Most disturbingly, a recent study of toddlers in the United States conducted by researchers at Duke University found flame retardants in the blood of every child they tested. The chemicals are associated with an assortment of health concerns, including antisocial behavior, impaired fertility, decreased birth weight, diabetes, memory loss, undescended testicles, lowered levels of male hormones and hyperthyroidism.
Heather Stapleton, a Duke University chemist who conducted many of the best-known studies of flame retardants, notes that foam is full of air. “So every time somebody sits on it,” she says, “all the air that’s in the foam gets expelled into the environment.” Studies have found that young children, who often play on the floor and put toys in their mouths, can have three times the levels of flame retardants in their blood as their parents. Flame retardants can also pass from mother to child through the placenta and through breast milk.
Logic would suggest that any new chemical used in consumer products be demonstrably safer than a compound it replaces, particularly one taken off the market for reasons related to human health. But of the 84,000 industrial chemicals registered for use in the United States, only about 200 have been evaluated for human safety by the Environmental Protection Agency. That’s because industrial chemicals are presumed safe unless proved otherwise, under the 1976 federal Toxic Substances Control Act.
When evidence begins to mount that a chemical endangers human health, manufacturers tend to withdraw it from the market and replace it with something whose effects — and often its ingredients — are unknown.
And then there is the graphic below… I was in agreement up until the suggestion to “vacuum with a HEPA filter several times a week.” Overkill perhaps, but the alternative is to replace the furniture with something less toxic.
