HELCOM Metadata catalogue
Polychlorinated biphenyls (PCB) and dioxins and furans 2018 biota data
This dataset represents the underlying data on core indicator PCB, dioxin and furan. The core indicator evaluates the status of the marine environment based on concentrations of dioxin and dioxin like compounds in Baltic Sea fish, crustacean and molluscs as well as on concentrations of non-dioxin like PCB in Baltic Sea fish. Good status is achieved when the concentrations of PCB, dioxin and furan are below the threshold values.
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 information:
"region" = name of subbasin
"country" = country
"station" = Unique code for the station
"stationNam" = name for the station
determinan = determinant parameter
"detGroup" = the grouping of determinands used to display the results
"species" = species of measurement
"_shape" = shape used to map assessment results
"colour" = colour used to map assessment results
"l3area" = HELCOM assessment unit on scale 3
"l4area" = HELCOM assessment unit on scale 4
"nyall" = total number of years of data
"nyfit" = number of years of data used in the assessment
"nypos" = number of years with at least one measurement above the limit of detection
"lastyear" = most recent year of data
"prtrend" = the significance of the change over the most recent 20 years; for the assessment conducted in November 2017 and published in June 2018, this is the period 1996-2016
"rtrend" = annual ‘linear’ change over the most recent 20 years
"meanLY" = fitted value in last monitoring year
"clLY" = upper one-sided 95% confidence limit on fitted value in last monitoring year
"HQS" = Threshold value
"HQSdiff" = difference between clLY and HQS
"HQSbelow" = whether the mean value in the last monitoring year is significantly below HQS

Data are extracted from the HELCOM COMBINE database, hosted by ICES. The COMBINE data stem from regular environmental monitoring programmes of the coastal countries. 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.
The overall confidence of the assessment is moderate.
