Update of background concentrations over Norway. NILU OR

Schneider, P.; Tønnesen, D.; Denby, B.

A methodology for creating a new dataset of estimated background concentrations of NO2, O3, PM10, and PM2.5 that are representative of a typical year over Norway, was developed. The dataset has a spatial resolution of 10 km × 10 km and an hourly temporal resolution. The methodology is based on a spatial mapping component for obtaining information on annual mean background concentrations, and a temporal characterization component, which uses long-term time series of station data to describe the typical development of background concentrations throughout a day and a year. When combined, these two components allow estimates of typical background concentrations at any time of the year at any location in Norway. Whereas the previously used VLUFT method of 1993 only provided spatially constant data at the county level, the new method presented here provides spatially continuous data at a comparatively high spatial resolution. Furthermore, while the previous method only gave a range of constant values that were considered valid throughout the entire year, the new technique provides continuous time series for a typical year at hourly resolution at any location in Norway.

Contaminants in fish from Etnefjord, Norway. NILU OR

Mariussen, E.; Schlabach, M.

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.
