Description of key information

Abiotic degradation

Tungsten is a stable element and cannot degrade chemically. It can however, sometimes reversibly, participate in numerous chemical reactions that can proceed under a wide range of common environmental conditions. Thereby, different chemical compounds containing tungsten can be formed and also cease to exist, but the process of degradation is not a relevant fate pathway for tungsten metal (ATSDR, 2005).

Biotic degradation

In accordance with column 2 of REACH Annex VII, a test for ready biodegradability does not need to be conducted as the substance is inorganic. The process of biodegradation is not a relevant fate pathway for inorganic metal elements such as tungsten.
