Biodegradation of brominated and organophosphorus flame retardants

- Many brominated flame retardants have been identified as persistent, bioaccumulative and toxic.
- Debromination of these chemicals under anaerobic conditions is well established.
- Debromination can, however, increase the toxicity of brominated flame retardants.
- Alternatives such as organophosphorus compounds are being used in increasing quantities.
- This is despite the fact that knowledge of their biodegradation is often lacking.
