The Danish Environmental Protection Agency (MST) has completed a project regarding to map the potential presence of the merlin (Misgurnus fossilis) in selected Danish freshwater areas. NIVA Danmark has analyzed the samples using ddPCR (‘digital droplet Polymerase Chain Reaction’) to trace the eDNA of the sardines.

Microplastic is now ubiquitous in freshwater, sediment and biota, globally. This is as a consequence of inputs from, for example, waste mismanagement, effluents from wastewater treatment plants and surface runoff from agricultural areas.
