All dust samples in a study contained hormone-disrupting PFAS chemicals

“After treatment, I was in a free fall. The Anticancer Lifestyle Program caught me and gave me the support I really needed.”

“I never imagined the online course would be so comprehensive, enjoyable, and easy to follow! ”

My breast cancer diagnosis was a wake up call. The Diet module helped me to learn the science behind the food rules I followed while raising my kids and has motivated me to get back to that healthier way of cooking and eating. Thank you!

Per- and polyfluoroalkyl substances (PFAS), organophosphate esters (OPEs), and polybrominated diphenyl ethers (PBDEs) are hormone-disrupting chemicals that migrate from building materials into air and dust. In this study, researchers all the dust samples contained endocrine disrupting chemicals: “All dust samples were hormonally active, showing antagonistic activity toward peroxisome proliferator-activated receptor ( $peroxisome proliferator-activated receptor lowercase gamma 2$ ) (100%; 46 of 46 samples), thyroid hormone receptor ( $TR β$ ) (89%; 41 samples), and androgen receptor (AR) (87%; 40 samples); agonist activity on estrogen receptor ( $ER α$ ) (96%; 44 samples); and binding competition with thyroxine ( $T_{4}$ ) on serum transporter transthyretin (TTR) (98%; 45 samples). Effects were observed with as little as $4 micrograms$ of extracted dust.”

Likewise a study done in North Carolina and published in the journal Environmental Science and Technology, measured dust collected from the main living areas in 184 homes and 49 fire stations. Researchers found a variety of PFAS chemicals in the samples tested.
