The flame retardants in your couch foam don’t stay put; in fact, these pesky chemicals perpetually migrate out and are found in high concentrations in household dust (as if dust bunnies weren’t sinister enough). If it were as simple as sweeping this dust under the proverbial rug, that would be that. But blood samples confirm that these chemicals are making their way into our bodies. In 2004, Americans had more than 15 times the levels of pentaBDE in their systems than Europeans. And toddlers have 3 times the levels of adults. PentaBDE was phased out of furniture foam in 2004, but discouragingly, it is being replaced with our old friend Tris (see fig 1). Meanwhile, the option to purchase flame-retardant-free furniture is diminishing to essentially nothing.
