The Marine Chemistry Working Group (MCWG) concentrates its work around the status and fate of pollutants (organic substances and trace metals) in marine ecosystems and chemical oceanography (nutrients and ocean acidification). The remit of the group includes analytical challenges encountered in determining, evaluating and reporting chemicals in marine compartments from sample preparation to the final result, as well as crucial steps to achieve satisfactory Quality Assurance. Contaminants of emerging concern (CECs) are highlighted as a major topic in this report, in terms of their identification, the collection of information on their presence, concentrations in marine compartments across the ICES area, their ecotoxicological potential, and the exchange of information on how to monitor these compounds. The occurrence of microplastics in sediments, current limitations with collection methods and the potential for these to act as vectors for pollutants was reviewed. During this reporting period, particular ...
