One group of elements attracting more and attention are so-called technology-critical (TCEs). In comparison with legacy pollutants, the anthropogenic impact TCEs on environment might still be minor, but various applications introduce them to most remote places in world including marine environment. area prone pollution is Baltic Sea, partly due lack water exchange North Sea. this study, a sediment core from German Sea was used analyze total 42 elemental mass fractions. Based radiometric...
During the last decade offshore wind energy production has become an important source of renewable energy. To ensure safe operation during lifetime turbine, steel structures need to be protected against corrosion. This work evaluates potential metal emissions and environmental impacts from galvanic anodes used for corrosion protection farms (OWFs) by applying a novel multi-tracer approach. A total 235 surface water samples different German North Sea OWFs were taken between 2016 2022 analyzed...
Concentrations of elements in the aquatic environment are a key parameter for various scientific fields such as biogeochemistry, biology and environmental science. Within this context, community asks new analytical protocols to be able quantify more periodic table. Therefore, requirements aqueous reference materials have increased drastically. Even though wide variety CRMs different water matrices available, certified values many (e.g., rare earth (REE), technology‐critical elements, Ga In,...
The North Sea and its coastal zones are heavily impacted by anthropogenic activities, which has resulted in significant chemical pollution ever since the beginning of industrialization Europe during 19th century. In order to assess Anthropocene, natural archives, such as sediment cores, can serve a valuable data source reconstruct historical emission trends verify effectiveness changing environmental legislation. this study, we investigated 90 contaminants covering inorganic organic...
To evaluate potential metal emissions from offshore wind farms (OWFs), 215 surface sediment samples different German North Sea OWFs taken between 2016 and 2022 were analyzed for their mass fractions of metals isotopic composition Sr. For the first time, this study provides large-scale elemental data previously proposed galvanic anode tracers Cd, Pb, Zn, Ga In. Results show that legacy pollutants Pb Zn mostly within known variability sediments. At current stage In as well Ga/In ratios do not...
Abstract As interest in the investigation of possible sources and environmental sinks technology-critical elements (TCEs) continues to grow, demand for reliable background level information these matrices increases. In this study, a time series ten years sediment samples from two different regions German North Sea were analyzed their mass fractions Ga, Ge, Nb, In, REEs, Ta (grain size fraction < 20 µm). Possible regional differences investigated order determine preliminary reference...
Abstract There is a complex interaction between pollution, climate change, the environment and people. This interplay of actions impacts particularly relevant in coastal regions, where land meets sea. To achieve sustainable development systems, better understanding necessary role impact pollution connectedness elements, namely, people, as well associated unfolding an integrated social–ecological system (SES). In this context, enabling capacity tools connecting scientific efforts to societal...
