Description of key information

Additional information

Substance is readily biodegradable (according to OECD criteria), as shown by a test according OECD guideline 301 A (Fraunhofer IME ,2011) and 301D (Gerike & Gode, 1990). Therefore, no further testing is required for a registration under REACH. However, additional information on half-life times is given by WHO (2002) and Environment Canada (2001).

Summary on the degradability of formaldehyde as given in WHO (2002) and Environment Canada (2001):

"Formaldehyde is degraded by various mixed microbial cultures obtained from sludges and sewage. Formaldehyde in lake water decomposed in approximately 30 hours under aerobic conditions at 20°C and in approximately 48 hours under anaerobic conditions (Kamata, 1966). Howard et al. (1991) estimated half-lives of 24–168 hours in surface water and 48–336 hours in groundwater based on scientific judgment and estimated aqueous aerobic biodegradation half-lives. The authors also estimated a soil half-life of 24–168 hours, based on estimated aqueous aerobic biodegradation half-lives."
