Key value for chemical safety assessment

Biodegradation in water:
readily biodegradable

Additional information

The potential for biodegradation of epsilon-Caprolactam has been comprehensively investigated. As indicated by the modified MITI (I) test (OECD 301 C), it is readily biodegradable according to OECD criteria since the degradation after 14 days was 82 % based on BOD (CITI, 1992). Results from other biodegradation tests indicate that epsilon-Caprolactam can be easily eliminated from water by biodegradation (Zahn & Wellens 1974 & 1980; BASF SE 1995 & 1982; Zahn. & Huber 1975; Pitter 1976)
