News Release 5-Nov-2021
University of California - Riverside
Polybrominated diphenyl ethers, or PBDEs, are a class of fire-retardant chemicals that are ubiquitous. They are found on upholstery, carpets, curtains, electronics, and even infant products. Flame retardants migrate out of products into dust that humans contact and can ingest. Considered to be global environmental pollutants, they have been detected in water, soil, air, food products, animals, and human tissues. They are found, too, in breast milk of women all over the world.
A research team led by scientists at the University of California, Riverside, has found that when female mice exposed to PBDEs pass on these neuroendocrine-disrupting chemicals to their developing offspring, the female offspring show traits relevant to autism spectrum disorders, or ASD. Their short-term social-recognition ability and long-term social memory is reduced significantly and the offspring show exaggerated “marble burying” behavior — repetitive behavior reminiscent of human compulsive behavior, a core symptom of ASD.

While most biomedical research is done using rodents, these studies have implications for humans. Like humans, mice live in social groups and communicate dominance and subordinate behavior while competing for access to resources. A mouse’s ability to recognize others is a key behavior with translational relevance to human social cognition.
“Consumers need to be aware they are being exposed to chemicals like PBDEs,” Curras-Collazo said. “You cannot avoid these chemicals since they are added to many indoor products in the home, school, car and airplane. To avoid them you can buy PBDE-free furniture or cover the foam in your furniture, choose less contaminated foods, and vacuum and mop frequently to remove PBDE-contaminated dust. It’s crucial that we understand that these chemicals are present in our bodies and what they are doing.”
