(Grace Olson) Since the 1990s, scientists have determined that harmful toxins from the environment accumulate within the tissues of the body. Now, researchers from the University of Alberta in Canada found that sweating helps remove these toxins, specifically a flame retardant chemical called polybrominated diphenyl ethers (PBDEs). Published in Biomedical Research International, the researchers highlighted that studying sweat, along with blood, is crucial to understanding the toxic compound.
