What are Polybrominated Biphenyls (PBBs) ?
CAS#:067774-32-7
Polybrominated biphenyls (PBBs) are manufactured chemicals.
They are added to the plastics used to make products like computer
monitors, televisions, textiles, plastic foams, etc. to make
them difficult to burn. PBBs can leave these plastics and find
their way into the environment. PBBs are usually colorless to
off-white solids. PBBs are mixtures of brominated biphenyl compounds
known as congeners.
In the United States, manufacturing of PBBs was stopped in
1976. PBBs are still around in the environment because they
do not degrade easily or quickly.

Prioritization of substances based on a combination of their
frequency, toxicity, and potential for human exposure at
National Priorities List (NPL) sites.
- Minimal Risk Levels (MRL)
The MRL is an estimate of the daily human exposure to a hazardous substance that is likely to be without appreciable risk of adverse, non-cancer health effects over a specified duration of exposure. The information in this MRL serves as a screening tool to help public health professionals decide where to look more closely to evaluate possible risk of adverse health effects from human exposure.
