  1. Sampling sites: NS 1: North Sea—Lower Saxony Wadden Sea; NS 2: North Sea—Schleswig–Holstein Wadden Sea; BS: Baltic Sea—Bodden National Park
  2. Italics: quantified substances; DP: sum of syn-DP and antiDP
  3. Trends: o: no significant linear trend; +: increase; −: decrease; blank: insufficient data, no trend calculation possible. Time intervals for trend calculations: blue mussels: NS 1: 1985–2015 BS: 1992–2015. For NS 2 and for eelpout filet, data were only available for 2015. Trend calculation based on lipid normalized concentrations. For full names of chemicals refer to Table 1
