Ecotoxicology

Understanding the transport, bioaccumulation and toxic effects of environmental pollutants in cold regions of the planet

  • Source-sink contaminant relationships
  • Food web bio-transport
  • Ecological effects
  • Climate-contaminant interactions
  • Monitoring tools and methodologies

The Northern regions of Scandinavia and Russia, including the Barents Sea, face serious environmental risks and problems mainly associated with long-range transported contaminants. Some persistent organic pollutants (POPs), as well as a few heavy metals, have been detected in alarmingly high concentrations in the abiotic and biotic environments of the North. Many of these contaminants biomagnify, resulting in very high concentrations in top predators or in humans that rely on natural resources for subsistence.

The environmental input of organic pollutants in the Arctic differs strongly from input into lower latitude ecosystems. Thus, basic knowledge about this environment, adaptations and life history strategies of the animals living in Northern Environments needs to be specially emphasised in ecotoxicology of Northern Environments. Akvaplan-niva is involved in studies that involve biodiversity, physiology (adaptations) and ecotoxicology. We believe that this is a strength that enables us to develop unique understandings of the function of selected ecosystems. The research team has also developed specialized methodologies for mapping and monitoring contaminated sediments in high-latitude coastal- and harbour-areas, focusing on the bioavailability of sediment bound contaminants as well as effects on pelagic and benthic organisms. Akvaplan-niva continues to be a key provider of environmental data to the Arctic Monitoring and Assessment Program (AMAP).
