HELCOM Metadata catalogue
Metals (Lead) 2018 water data
This dataset represents the underlying water data on core indicator Heavy metals – Lead.The core indicator evaluates the status of the marine environment based on concentrations of heavy metal Lead (Pb) in water, fish liver and sediments. Quantitative thresholds are 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.
The Core indicator 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" = MIME subregion
"country" = country
"station" = Unique text that identifies the station
"stationNam" = name for the station
"determinan" = determinant parameter (PB = Lead)
"detGroup" = the grouping of determinands used to display the results
"filtered" = Filtered or unfiltered water sample used in analysis
"_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
"EQS" = Threshold value
"EQSdiff" = difference between clLY and EQS
"EQSbelow" = whether the mean value in the last monitoring year is significantly below EQS

- 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 lead in water, fish liver and bottom sediments up to 2016 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.
