Monitoring results indicate generally low levels of contaminants in the Barents Sea - although with some exceptions. The levels of most heavy metals are low, with the exception of Ni and As in sediments. Levels of atmospheric input of heavy metals into the area are decreasing for some metals, but increasing for others. For most of the monitored substances in the Barents Sea the levels of contamination are well below the limit values for human consumption. The concentration of heavy metals and POPs is generally lower in the Arctic environment than in temperate regions but in the last few years there is a tendency for an increase in concentration in air for some POPs like HCB and PAH. Persistent organic pollutants (POPs) that accumulate in organisms at the top of the food chain are of special concern. Another matter of concern is distribution and contents of radioactive substances in the marine environment which may pose major risks to the whole ecosystem.
This section present extended information on pollution issues shown in themes presented in the GIS Service. Observe that there are currently no GIS maps in the category Contaminants in seabirds, but figures are made to give a visual picture of pollution levels in common seabirds, and in their muscle and liver tissues, and i egg.
Please go to the themes shown in the fly-out menu under MAP SERVICE/Pollution to find articles.
More than 100 experts from a total of 9 Russian and 20 Norwegian institutions have participated in the preparation of the report, and the work has been organized in 13 expert groups. The work has been led by Sevmorgeo and PINRO on Russian side and on Norwegian side by the Institute of Marine Research and the Norwegian Polar Institute..Find author name here...
BarentsPortal is a project developed under the Joint Russian - Norwegian Commission on Environmental Cooperation. The joint environmental report is a co-operation project between the Joint Russian - Norwegian Commission on Environmental Cooperation and the Joint Russian-Norwegian Fisheries Commission
Our MAP SERVICE, currently as beta version, is an instrument to present aggregated, joint Russian and Norwegian environmental data from the Barents Sea and adjacent sea areas as map presentations. This give you the opportunity to have a more geographic focus on some of the environmental issues shown in the joint environmental report, or broaden your knowledge on other themes that are only briefly or hardly mention in the report. New, interesting themes, will be added as soon as our joint effort bring to light aggregated, novel environmental information.
In our MAP INFO SERVICE you will find comments and metadata for shown maps, or on other themes not shown in the status report or even in the MAP Service.
You will find metadata and other information in the MAP Info Service section, and the themes are organised as for the MAP Service.
