Perfluorooctane sulphonate PFOS in water results HOLAS 3
This core indicator evaluates the status of the marine environment based on concentrations of perfluorooctane sulphonate (PFOS) in water. Quantitative thresholds are used to evaluate if core indicators status is "Achieve", "Fail" or "Not assessed". Good status is achieved when the concentrations of PFOS are below the threshold value.
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

-
The data used in the assessment is based on data from the HELCOM COMBINE database to which Contracting Parties report regular monitoring data.The data are extracted based on the HELCOM core indicator extraction table. The assessment protocol is structured in three main parts, 1) changes in log concentrations over time are modelled, 2) check for compliance against threshold value and evidence for temporal change of contaminant concentration per station and 3) a spatial aggregation of status per assessment unit. Confidence of the indicator evaluation results is considered to be high for those areas for which data are available.
