%X In this study, Al and Zn anodes from several manufacturers were analyzed using inductively coupled plasma mass spectrometry (ICP-MS) based techniques to identify suitable tracers for anode specific emissions as wells as the content of elements of environmental concern. High mass fractions of rare and/or technology- and environmentally-critical elements such as In (≤ 230 mg/kg), Ga (≤ 130 mg/kg), Cd (≤ 700 mg/kg), and Pb (≤ 20 mg/kg) were found. ICP-MS-based techniques were developed for the quantification of new tracer analytes, such as In and Ga, and applied to water, sediment and biota (Mytilidae) samples from inside and around offshore wind farms located in the German North Sea. First results of elemental concentrations in biota (Mytilidae) and spatial trends in seawater and sediment samples will be presented and discussed.
