The tungsten content in water is measured using the same method as other metals i.e. with ICP-MS, but our analysis is not accredited. For more information about the analysis method, see Metals in water (ICP-MS).
Tungsten measurements have mainly taken place in the Kolbäcksån water system due to a significant impact through the industry in the lower part of the system.
We are presently not analysing tungsten.
