Should you throw out your black plastic spatula? A recent study that reported alarming levels of several flame retardants in common black-colored plastic items (including cooking utensils, toys and hair products) had many people suddenly taking stock of their inky array of plastic kitchenware and considering wood or metal alternatives. And the reasons for the concern were understandable: the study’s findings, published in Chemosphere, highlighted potential health effects from exposure to the flame retardants, particularly decabromodiphenyl ether (decaBDE)—a chemical the U.S. Environmental Protection Agency banned in 2021 for its apparent links to cancer and reproductive, developmental and immunologic toxicity effects.
But this week the study’s authors issued a correction that suggests exposure to decaBDE from the tested products isn’t as close to the EPA’s safety reference level as they initially thought. The decaBDE exposure they estimated from the screened products is still correct, but it’s one tenth of the reference dose. The study had miscalculated the comparison by an order of magnitude.
The amount of flame retardants in such products is “not as harmful, with respect to the EPA guidance, as [the researchers] originally stated, although, with these chemicals, they may be harmful when you’re exposed to small amounts over a long period of time,” says Andrew Turner, a biogeochemist at the University of Plymouth in England, who wasn’t involved in the research and studies the disposal and recycling of plastic consumer goods. “It’s difficult to put numbers on these chemicals.”
