2019-9-6 · Osimitz et al. suggest that we mischaracterized all halogenated flame retardants (FRs) by classifying them as one class of hazardous compounds. We agree that there are differences among FR classes and subclasses. However, over the past two decades, we have repeatedly observed a pattern of regrettable substitutions, in which one harmful FR was replaced by another that was later found to be ...
November 30, 2012 — Flame retardants found in furniture, cars, carpet padding, and baby products are supposed to make these products safer. But according to neuropsychologist and epidemiologist Brenda Eskenazi, they may do more harm than good—particularly in children, who are more vulnerable to environmental hazards than adults.
