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.

VOC measurements by PTR-ToF-MS at the Birkenes Observatory. A summary report. NILU OR
A high resolution proton-transfer-reaction time-of-flight mass spectrometer (PTR-ToF- MS) was used for on-line and real-time measurements of volatile organic compounds (VOCs) at the Birkenes Observatory in Southern Norway. Measurements were carried out during late spring and summer 2012 and in January and early February 2013. Here we present the obtained PTR-MS standard data product which includes volume mixing ratios of methanol, acetonitrile, acetaldehyde, acetone, dimethyl sulphide, isoprene, methacrolein plus methylvinylketone, methylethylketone, benzene, toluene, C8-alkylbenzenes, C9-alkylbenzenes and the sum of the monoterpene isomers. Exploratory data of formic acid, acetic acid, pinonaldehyde and three unidentified signals (m/z 87.080, m/z 89.060 and m/z 101.098) are also shown. PTR-ToF-MS mass spectra were dominated by oxygenated VOCs both in summer and in winter. Pure hydrocarbons were mostly aromatic hydrocarbons (benzene, toluene, C8-alkylbenzenes) in winter and biogenic hydrocarbons (monoterpenes and isoprene) in summer. The summertime data confirm that the Birkenes Observatory is an interesting site in the boreo-nemoral vegetation zone where it is possible to observe both monoterpene and isoprene emissions and their photochemical processing in the atmosphere.

The report describes future emission factors under different scenarios.This report is the final version of GMOS Deliverable D 2.4 Report on mapping of Hg emissions and its chemical forms for 2030. It presents the emission maps of the Current Policy (CP), New Policy (NP) and Maximum Feasible Reduction (MFR) global mercury emission scenarios for 2035.

Emissions from domestic heating due to woodburning are one of the main emissions sources of PM in Norway. However there are uncertianties in the emission data and especially how much these emissions contribute to the concentrations. Dispersion modeling has been performed for Oslo with different emission scenarios to test some of the parameters related to this emission source. The model results show that the wood burning contribution is overestimated, especially in the evening and conclusions are that the emissions of wood burning are wrong both in quantity as well as spacial distribution in time variation.
