Grenseområdene Norge-Russland. Luft- og nedbørkvalitet, april 2010-mars 2011. NILU OR
Smelteverkene på russisk side av den norsk-russiske grense slipper ut store mengder svoveldioksid (SO2) og tungmetaller. Dette gir forhøyede konsentrasjoner også på norsk side. Denne rapporten inngår i kartlegging av miljøbelastningen i grenseområdene og omfatter målinger av luftkvalitet, nedbørkvalitet og meteorologi.

Abu Dhabi traffic emissions inventory 2009. NILU OR
This report is part of a larger emissions inventory for the emirate of Abu Dhabi, which consists of industrial and traffic sources. Traffic emissions in Abu Dhabi are a major contributor to air emissions due to the large and inefficient cars used by most of the population, coupled with the high mileages drive annually. The report presents the results of the necessary data collected pertaining to traffic within the emirate.
A bottom-up approach was used for accumulating the total emissions attributed to transport, whereby the mileages, travel conditions, and age of the vehicles were taken into account and modelled. A gap analysis is presented in order to clarify the assumptions made during the modelling, and where the future updates to the emission inventory would benefit the most in terms of data collection.

E136 Breivika - Lerstad, Ålesund kommune. Vurdering av luftforurensning fra tunnelmunninger. NILU OR
Spredningsberegninger for tunnelforbindelser langs E136 Breivika - Lerstad, Ålesund kommune. Det er beregnet maksimale konsentrasjoner av PM10,og NOX i tunnelene ved ugunstige trafikkforhold (rushtrafikk morgen/ettermiddag). Konsentrasjonsreduksjon som funksjon av avstand fra tunnelmunninger er vist i tabell, og konsentrasjonene er sammenlignet med Nasjonalt mål og grenseverdier for luftkvalitet.

Contaminants in fish from Etnefjord, Norway. NILU OR
1,2,5,6,9,10-hexabromocyclododecane (HBCDD) is one of the most frequently used brominated flame retardants (BFR) and is considered as an emerging environmental pollutant. Recently, high levels of HBCDD were reported in five different fish species from Etnefjord, which is a branch of the Hardangerfjord at the southwest coast of Norway. This report raised some serious concerns and the Norwegian Climate and Pollution Agency (Klif) therefore initiated a survey of HBCDD in cod and flounder from Etnefjorden in order to confirm the findings. In addition to HBCDD, the levels of other environmental pollutants were analyzed in the fish, namely polybrominated diphenyl ethers (PBDEs), polychlorinated biphenyls (PCBs), hexachlorocyclohexane (HCH), dichlorodiphenyltrichloroethane (DDT), mercury (Mg), lead (Pb), cadmium (Cd) and arsenic (As). The fish muscle filet and livers were prepared and analyzed using recognized and previously published methods. The levels of HBCDD in the fish were low, representing expected background concentrations. HBCDD was only detected in the cod livers with concentrations ranging 0.3-5.7 ng/g wet weight, corresponding to 1.3-8.2 ng/g on a lipid weight basis. Previously, it was reported a level of 30 000 ng/g lipid weight in cod filet, which is, as far as we know, the highest HBCDD concentration ever reported in cod. Our study could, therefore, not confirm the recent findings that showed high HBCDD concentrations in fish from the Etnefjord area. Also, the levels of the other pollutants were low. For example, the concentrations of DDT, PCB, HCH and Hg can, according to Klifs system for classification of environmental state, be regarded as background levels (class 1, slightly/negligible polluted). In conclusion, there are no recons to believe that cod and flounder in Etnefjorden is exposed to considerable amount of environmental pollutants, neither of HBCDD nor other contaminants. Only further analysis of sediments from the inner site of the fjord can, however, positively reveal a possible HBCDD source.

Monitoring of the atmospheric ozone layer and natural ultraviolet radiation. Annual report 2010. NILU OR
Rapporten presenterer måledata for totalozon, vertikalfordelingen av ozon og UV-stråling over norske målestasjoner i 2010. For Oslo og Andøya er trenden i totalozon beregnet for perioden 1979-2010.
Ozonverdiene over Norge var generelt høye i 2010. Den klare reduksjonen av ozonlaget over Norge i perioden 1979-1997 stoppet opp i 1998 og ozonlaget over Norge ser nå ut til å ha stabilisert seg.
