Total Phosphorus

Total Phosphorus

Known issues with the databases Anomalous total phosphorus levels have been revealed for the period January 1991 – June 1996. The anomaly has been shown to be likely to result from an absolute error,

Geochemical laboratory

Chemical oxygen demand, CODMn

Chemical oxygen demand, CODMn

Known issues in the database Since January 2019 are the results reported as COD Mn i.e. in the unit mg O/l. Until December 2018 was only the amount of oxidant used (permanganattal) is given in our

Tungsten/Wolfram, W

Tungsten/Wolfram, W

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
