Multimedia models and observations in concert. A powerful tool to understand and manage organic contaminants. NILU OR

Krogseth, I.S.; Breivik, K.

This report summarizes results from a project funded by the Research Council of Norway (196191/S30). The overall goal was to better understand and predict relationships between emissions of organic chemicals of emerging concern and their levels in the environment and food-chains of the Nordic region through integrated monitoring and modeling studies. Four case studies were selected (i) cyclic volatile methyl siloxanes (cVMSs) in the Inner Oslofjord, (ii) cVMSs in the Norwegian Arctic (iii) short-chain chlorinated paraffins (SCCPs) in the Nordic environment and (iv) risk-based model screening of chemicals in commerce in the Nordic countries. We also provide a brief introduction to the key multimedia modelling tools which were used. It is our hope that these tools, targeting the behaviour of contaminants under relevant environmental and climatic conditions, may assist Nordic environmental authorities interested in understanding and managing organic contaminants.

Measurement data July 2012 - June 2013. Environmental monitoring of emissions to air from Snøhvit-Hammerfest LNG. NILU OR

Hak, C.

Statoil assigned NILU ¿ Norwegian Institute for Air Research to carry out a programme on "Environmental monitoring of emissions to air from the Snøhvit LNG facility". The project started on 1 February 2006. This report summarises the results of the measurement programme from 1 July 2012 to 30 June 2013. It involves the measurement of meteorological parameters on Melkøya and Fuglenesodden. Air quality parameters were measured at Fuglenesodden. Precipitation samples taken at Forsøl and Kargeneset were analysed for PAHs, inorganic ions, heavy metals and mercury. The current air quality standards are met for all compounds.

Air quality maps of NO2 and PM10 for the region including Stavanger, Sandnes, Randaberg and Sola (Nord-Jæren). Documentation of methodology. NILU TR

Denby, B.R.; Sundvor, I.; Schneider, P.; Vo, D.T.

This report documents the methodology used to make air quality maps of NO2 and PM10 for the region Nord-Jæren, which includes the municipalities of Stavanger, Sandnes, Randaberg and Sola. It provides support documentation for the summary report OR 57/2013.

Screening of environmental pollutants in seabird eggs from Sklinna and Røst. NILU OR

Huber, S.; Nygård, T.; Warner, N.A.; Remberger, M.; Harju, M.; Uggerud, H.T.; Kaj, L.; Schlabach, M.; Hanssen, L.

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.
