Screening of environmental pollutants in seabird eggs from Sklinna and Røst. NILU OR
Within the present screening project concentration levels of a broad range of inorganic and organic environmental contaminants in seabird eggs of the common eider, shag and herring gull collected at the islands Sklinna and Røst were targeted for analysis ranging from metals, organotin, polycyclic aromatic hydrocarbons, polychlorinated biphenyls and metabolites, chlorinated paraffins, organochlorine pesticides and other pesticides, per- and polyfluoroalkylated substances, dechlorane pluss, octachlorostyrene, phosphororganic and brominated flame retardants, bromo- and alkylphenols, siloxanes and phthalates. In total 201 different chemical compounds were analysed, whereas 53 single compounds have not been detected over the limit of detection. Additionally other parameters as stable isotopes of ¿15N and ¿13C and lipid content were investigated. The purpose of this report is to provide an updated assessment of pollution present within marine environment in Norway.

Screening of compounds in tire wear road run off
Tire related additive chemicals can leach out and enter the environment. Road run-off and recipient waters are particularly prone to contamination by these chemicals, though data from large screening studies is lacking. Here, we present data from water (road run-off & recipients, atmospheric deposition (rain), snow), sediment (marine, snow dumping sites) and biota (blue mussels) samples collected in the Nordic countries. The aim of this study was to provide a first assessment of the presence of tire related chemicals in road run-off and associated samples in the Nordic countries. Tire related additive chemicals were detected in 85 out of 87 samples, with varying concentrations depending on the sample type and location.

Screening of Chlorinated Paraffins, Dechloranes and UV-filters in Nordic Countries
In 2019, the Nordic screening group decided to perform a Nordic screening on chlorinated paraffins, dechloranes and UV-filters. These compounds are used in a wide range of applications. They all have long range transport characteristics and can potentially be regulated under the Stockholm POP convention. However, there are still huge data gaps, which need to be addressed in order to fulfill regulation requests. Several topics and questions were in focus for more measurements and a deeper understanding: (1) importance of long-range atmospheric transport and deposition, (2) differences/similarities in terrestrial versus marine food chains, and (3) variations between the Nordic countries and between urban and remote areas. Based on these priorities, availability of samples, and other practical reasons, samples from different Nordic countries, different environments, and both urban and remote places were selected. This study includes analysis of the compounds in air, marine and freshwater fish and marine mammals and bird eggs, but as the chlorinated paraffins also have been found to accumulate in the terrestrial food web, terrestrial mammals and bird eggs were included as well. Additionally, samples of pine needles were analysed both to look at the possibility for long range transport and to investigate it as a possible source of chlorinated paraffins for the terrestrial mammals.

Screening new PFAS compounds 2018
This screening project has focused on the occurrence of conventional and emerging PFASs in terrestrial and marine environments, including the Arctic. Conventional PFASs were found to be wide-spread in the environment and for the first time in Norway reported in wolf, a top predator from the terrestrial environment. Otters living in close proximity to human settlements and preying on the marine food chain, are heavily contaminated with PFASs. Areas where ski-testing activities are common are a potential “hotspot” where PFASs can enter the food chain. The difference in PFAS-profile between the samples indicates that the diversity in samples are necessary to reveal the complete picture of PFASs in the environment.
