Pollution of heavy metals and other toxins in the sea around the country is generally well below international standards, as stated in Matís' new report on changes in the marine environment around the country (here)
The concentration of cadmium in Icelandic mussels, however, is higher than is generally the case in mussels from the waters of Europe and America.
Since 1989, an annual monitoring project of pollutants in the marine environment of Iceland has been underway. The project is funded by the Ministry of the Environment, the Ministry of Fisheries and Agriculture and Matís ohf. The Environment Agency is the administrator of the project.
Various pollutants in the ocean can enter marine organisms or organisms that feed on seafood. In many cases, this pollution is man-made and there is growing concern about this development. Pollutants are transported by air and sea currents from mainland Europe and America as well as pollution from Iceland. It is therefore important to monitor the amount of pollutants in Iceland, both in the environment and in the organisms that live in the country. It is also important to be able to compare the state of the marine life around Iceland with the situation in other countries, not least because of the importance of marine products to the nation.
In the Matís report (report 24-11 on the Matís website) the results of the monitoring project for the years 2009 and 2010 are published. trans-nonachlor, toxaphen, DDT and PBDE. The aim of the monitoring project is to identify changes that may occur in the concentration of trace elements in the marine environment around the country during a certain period and between different ocean and coastal areas. Among other things, the research is important for the sale of Icelandic seafood in both domestic and foreign markets, where it can be demonstrated with scientific data that Icelandic fish is caught in an unpolluted environment.
The report states that the concentration of heavy metals such as mercury is very low. However, the concentration of cadmium has sometimes been higher in the marine environment in Iceland than in more southerly areas. However, the amount of cadmium is low in the organisms studied, for example in the range of 0.1-1 mg / kg in mussels. The high concentration of cadmium in Iceland is regional and is considered to have natural causes as there is no evidence of man-made cadmium pollution. The results show changes in the pattern of chlorine organic matter in mussels collected near Hvalstöðin in Hvalfjörður in September 2009, there were no visible changes in the concentration of these substances at the mussel collection site at Hvammsvík in Hvalfjörður or at any other collection site around the country studied in 2009. Important is monitoring these changes in the pattern of concentration of chlorinated organic substances in mussels in the monitoring project in the coming years to see if they are still present. A detailed statistical analysis of the data is in progress, i.e. Scientific methods can be used to estimate the increase or decrease of pollutants in the marine environment in Iceland.
