The coastal abiotic marine environment can be regarded as the starting point for the accumulation and magnification of toxic chemicals in the marine food chain. This is especially the case for the long-living hydrophobic persistent organic pollutants (POPs) and their replacement chemicals. The latter are often considered as emerging contaminants. They may have similar substance properties as their banned predecessor and can be as problematic or even worse for marine ecosystems (“regrettable substitutes”).

In general, the availability of scientific data on emerging contaminants in the coastal, marine and polar environment is very limited, see World Ocean Assessment by the United Nations

Our current research activities focus on the investigation of the occurrence, sources, transport, fate and trends of classical and emerging persistent anthropogenic pollutants in the coastal marine and polar environment. Our analytical portfolio comprises more than 300 individual substances, including emerging contaminants such as Per- and Polyfluorinated Chemicals (PFASs), alternative Flame Retardants (aFRs), UV-Stabilizers, Pharmaceuticals and Personal Care Products (PPCPs) as well as Current-Use Pesticides (CUPs).

GMOS-TRAIN is a European training network, which includes fifteen doctoral candidates from ten institutions, that aims to improve our understanding of the global mercury cycle and to support the implementation of the Minamata Convention. In the course of the “Innovative Training Network” (ITN), fifteen ESRs (early stage researchers) at ten institutions will be trained in the fields of atmospheric and oceanic mercury analytics and modelling. Two of them will work at HZG. In addition, six further network doctoral candidates will at times be guests at HZG. Some aspects of GMOS-TRAIN include developing new measurement technologies, determining reaction rates, and modelling global transport and accumulation along the food chain.
