EU-kalat is a study, where concentrations of PCDD/Fs, PCBs, PBDEs and heavy metals have been measured from fish

Question

The scope of EU-kalat study was to measure concentrations of persistent organic pollutants (POPs) including dioxin (PCDD/F), PCB and BDE in fish from Baltic sea and Finnish inland lakes and rivers. [1] [2] [3].

Answer

Dioxin concentrations in Baltic herring.

The original sample results can be acquired from Opasnet base. The study showed that levels of PCDD/Fs and PCBs depends especially on the fish species. Highest levels were on salmon and large sized herring. Levels of PCDD/Fs exceeded maximum level of 4 pg TEQ/g fw multiple times. Levels of PCDD/Fs were correlated positively with age of the fish.

Mean congener concentrations as WHO2005-TEQ in Baltic herring can be printed out with this link or by running the codel below.

Rationale

Data

Data was collected between 2009-2010. The study contains years, tissue type, fish species, and fat content for each concentration measurement. Number of observations is 285.

There is a new study EU-kalat 3, which will produce results in 2016.

Calculations

Preprocess

  • Preprocess model 22.2.2017 [4]
  • Model run 25.1.2017 [5]
  • Model run 22.5.2017 with new ovariables euRaw, euAll, euMain, and euRatio [6]
  • Model run 23.5.2017 with adjusted ovariables euRaw, eu, euRatio [7]
  • Model run 11.10.2017: Small herring and Large herring added as new species [8]
  • Model rerun 15.11.2017 because the previous stored run was lost in update [9]
  • Model run 21.3.2018: Small and large herring replaced by actual fish length [10]
  • Model run 26.3.2018 eu2 moved here [11]

Bayes model for dioxin concentrations

  • Model run 28.2.2017 [12]
  • Model run 28.2.2017 with corrected survey model [13]
  • Model run 28.2.2017 with Mu estimates [14]
  • Model run 1.3.2017 [15]
  • Model run 23.4.2017 [16] produces list conc.param and ovariable concentration
  • Model run 24.4.2017 [17]
  • Model run 19.5.2017 without ovariable concentration [18] ⇤--#: . The model does not mix well, so the results should not be used for final results. (type: truth, paradigm: science view) --Jouni (talk) 19:37, 19 May 2017 (UTC)
----#: . Maybe we should just estimate TEQs until the problem is fixed. (type: truth, paradigm: science view) --Jouni (talk) 19:37, 19 May 2017 (UTC)
  • Model run 22.5.2017 with TEQdx and TEQpcb as the only Compounds [19]
  • Model run 23.5.2017 debugged [20] [21] [22]
  • Model run 24.5.2017 TEQdx, TECpcb -> PCDDF, PCB [23]
  • Model run 11.10.2017 with small and large herring [24] (removed in update)
  • Model run 12.3.2018: bugs fixed with data used in Bayes. In addition, redundant fish species removed and Omega assumed to be the same for herring and salmon. [25]
  • Model run 22.3.2018 [26] Model does not mix well. Thinning gives little help?
  • Model run 25.3.2018 with conc.param as ovariable [27]

Initiate conc_pcddf

  • Model run 19.5.2017 [28]
  • Model run 23.5.2017 with bugs fixed [29]
  • Model run 12.10.2017: TEQ calculation added [30]
  • Model rerun 15.11.2017 because the previous stored run was lost in update [31]
  • 12.3.2018 adjusted to match the same Omega for all fish species [32]
  • 26.3.2018 includes length and time as parameters, lengt ovariable initiated here [33]

⇤--#: . These codes should be coherent with POPs in Baltic herring. (type: truth, paradigm: science view) --Jouni (talk) 12:14, 7 June 2017 (UTC)
