The fixed and relative standard deviation (\(s\) and \(v\)) derived from the ICES data base (extraction date: 15 February 2019) and used to estimate missing uncertainties are tabulated below for biota, sediment and water. The unit only applies to the fixed standard deviation; the relative standard deviation is unitless. The notes at the bottom of each table describe the approach taken when there were insufficient data in the ICES data base to derive the fixed and relative standard deviations.

- NAP2OH, PYR1OHEQ: \(s\) and \(v\) were set to 0 and 0,2 for compatability with PA1OH and BAP3OH (no uncertainties or limits of detection in the data base)
- ACHE: \(v\) was set to 0.4 (median value) and \(s\) was set to 0 (no limits of detection)
- GST: \(v\) was set to 0.2 (median value) and \(s\) was set to 0 (no limits of detection)
- ALAD: \(s\) and \(v\) were set to 0 and 0.2 based on typical values for other biological effects (no uncertainties or limits of detection)
