Description of key information

Bisphenol A was found to be rapidly biodegraded by microbial consortia found in many natural waters and sediments, with lag times and half-lives on the order of a few days. 

Key value for chemical safety assessment

Additional information

Biodegradation simulation tests have measured the die-away of Bisphenol A using surface water and sediments collected from rivers, estuaries, and marine waters in North America, Europe, Japan, and Australia. Bisphenol A was found to be rapidly biodegraded by the microbial consortia found in the natural waters and sediments, with lag times and half-lives on the order of a few days. Biodegradation rates are expected to be slower and half-lives longer in tests conducted using lower temperatures and oxygen content. Microbial populations capable of rapidly biodegrading Bisphenol A appear to be ubiquitous in the environment. The biotransformation pathways for Bisphenol A have been defined in several studies.
