Metals - Mercury in biota results HOLAS 3

This core indicator evaluates the status of the marine environment based on concentrations of heavy metal Mercury (Hg) in fish muscle. Quantitative threshold value is used to evaluate if core indicators status is "Achieve", "Fail" or "Not assessed". Threshold values are based on Environmental quality standards (EQS), defined at EU level for substances included in the priority list under the Water Framework Directive.


This dataset displays the result of the indicator in HELCOM Assessment Scale 4 (Division of the Baltic Sea into 17 sub-basins and further division into coastal and off-shore areas and division of the coastal areas by WFD water types or water bodies).


Attribute specifications and units:

"HELCOM_ID" = Code of the HELCOM scale 4 assessment unit

"country": country in which the HELCOM assessment unit is located or a mention to an open sea area

"level_2" = Name of the HELCOM assessment unit in scale 2

"Name" = Name of the HELCOM assessment unit in scale 4

"Open_sea" = Name of the HELCOM assessment unit in the open sea

"F2_Name" = Name of the HELCOM assessment unit

"determinan" = Determinat

"est" = The estimated mean loge concentration in the assessment unit

"se" = The standard error on the estimated mean log concentration in the assessment unit

"fit" = The estimated mean concentration in the assessment unit

"upper_cl" = Upper one-sided 95% confidence limit on the mean concentration: exp(est + qnorm(0.95) * see)

"Status" = Overall Status of the indicator according to one-out-all-out

Statement

The indicator is based on data held in the HELCOM COMBINE database, hosted at the International Council for the Exploration of the Seas (ICES). All available data on Mercury in fish muscle up to 2021 were used. Evaluation is carried out using an agreed R-script that runs a statistical analysis. The overall confidence of the indicator evaluation is high.
