Anthropogenic contaminants enter the marine environment directly from land-based sources, however they can also be emitted or re-mobilised in the marine environment. The EU Marine Strategy Framework Directive (MSFD) is responsible for providing provisions against the pollution of marine waters by chemical substances. These contaminants are of great concern due to their known toxicological effects (i.e., endocrine disruption, immunotoxicity), with some known to accumulative in organisms and food webs. However, it is impossible to capture all contaminants that may be present in this dynamic marine environment. As a result, many of these chemicals and chemical mixtures have been characterised as ‘contaminants of emerging concern’ (CECs). Passive samplers can accumulate pollutants and concentrate sufficient amounts of pollutants from water for chemical analysis where spot sampling methods often fail. This study evaluates the use of a novel dynamic passive sampling approach for the determination of CECs in seawater.
