The figure consists of seven maps showing the four regional seas, one map for each contaminant. Each map shows the locations where the contaminant was measured, and coloured to indicate which class was registered; green (Low concentration), yellow (Moderate concentration) or red (High concentration). In addition a pie chart is presented on the map showing the percent of each class within each of the four regional seas. Furthermore, any regional trend for a particular class is indicated by an arrow.
Indication of classification on maps is unitless and the pie chart are percent. The classification on the maps is based on concentrations in µg/kg which are then classified into one of three classes.
