Environmental Contaminants in an Urban Fjord, 2021
This report presents data from the first year of a new 5-year period of the Urban Fjord programme. The programme started in 2013 and has since been altered/advanced. In 2021 the programme covers sampling and analyses of stormwater, river water, effluent from a wastewater treatment plant (inputs to the fjord), fjord sediment, blue mussel, cod and (river) trout, all from the Inner Oslofjord area. A total of 260 single compounds/isomers were analysed and frequent detection was found of benzothiazoles in abiotic aqueous phases, UV-compounds in most matrices, metals in all matrices, PBDEs in biota, chlorinated paraffins in all matrices and PCBs in biota and abiotic particle phases.

Environmental Contaminants in an Urban Fjord, 2020
This programme, “Environmental Contaminants in an Urban Fjord” has covered sampling and analyses of sediment and organisms in a marine food web of the Inner Oslofjord, in addition to samples of blood and eggs from herring gull. The programme also included inputs of pollutants via surface water (stormwater), and effluent water and sludge from a wastewater treatment plant. The bioaccumulation potential of the contaminants in the Oslo fjord food web was evaluated. The exposure to/accumulation of the contaminants was also assessed in birds. A vast number of chemical parameters have been quantified, in addition to some biological effect parameters in cod, and the report serves as a status description of the concentrations of these chemicals in different compartments of the Inner Oslofjord marine ecosystem.

Environmental Contaminants in an Urban Fjord, 2018
This programme, “Environmental Contaminants in an Urban Fjord” has covered sampling and analyses of sediment and organisms in a marine food web of the Inner Oslofjord, in addition to samples of blood and eggs from herring gull and eider duck. The programme also included inputs of pollutants via surface water (storm water), and effluent water and sludge from a sewage treatment plant. The bioaccumulation potential of the contaminants in the Oslo fjord food web was evaluated. The exposure to/accumulation of the contaminants was also assessed in birds. A vast number of chemical parameters have been quantified, in addition to some biological effect parameters in cod, and the report serves as valuable documentation of the concentrations of these chemicals in different compartments of the Inner Oslofjord marine ecosystem.
