River pearl mussel in Varde Å

NIVA Denmark has carried out a study in which eDNA from the rare river pearl mussel has been found in two tributaries to Varde Å – namely in the outlet from Ansager Å and at four locations in Holme Å. The study has been financed by the Aage V. Jensen Foundation, Varde municipality and the Danish Environmental Protection Agency.

Plastic recycling plant as a point source of microplastics to sediment and macroinvertebrates in a remote stream

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.

Digital droplet Polymerase Chain Reaction (ddPCR)

By: Steen W. Knudsen

For many years now, NIVA has analyzed water samples for the presence of environmental DNA (abbreviated: ‘eDNA’), both in fresh and marine ecosystems. Among other things, NIVA Denmark has completed the MONIS project (‘Monitoring of non-indigenous species in marine waters’ 2014-2023) on behalf of the Danish Environmental Protection Agency.

In continuation of the MONIS project, in May 2022 NIVA Denmark acquired a so-called ‘digital droplet Polymerase Chain Reaction’ machine (ddPCR machine) and had it installed in the laboratory at the University of Copenhagen at the Natural History Museum of Denmark which NIVA Denmark uses to make analyzes of eDNA.
