NILU has carried out a monitoring program regarding meteorology and air quality in Sauda during the periode 01.04.-30.09.2010. Filters have been investigated regarding several metallic compounds.

EAD air quality monitoring network. Site survay for 10 new stations. NILU OR
Recommendations for additional monitoring stations in Abu Dhabi have been based on monitoring criteria and the objectives for measurements. It has been stressed that measurements have to be performed based on a number of permanent air quality stations. Also the meteorological measurements have to be co-ordinated with the permanent stations.
Based on the evaluations performed in Abu Dhabi, we have proposed three sites which should be developed and started immediately (1-3). Another three areas have been indicated for future and further evaluations. However, we believe that there will be a need in the near future also for measurements in these areas.

Inert dispersion of a unitary emission has been combined with time dependent air chemistry to provide maximum impact of nitrosamines and nitramines in air and water for emissions from the amine absorber at TCM. The calculations show that likely case impact of nitrosamines and nitramines in air is less than 2 % of the recommended guideline value. The maximum concentrations in fresh water range from0.6 % to 3.2 % of the guideline depending on the use of absorbent and flue gas. The likely case impact show that air concentrations are a factor of 3 to 4 lower than the worst case, while water concentrations are be a factor from 16 to 22 lower than the worst case depending on the type of absorbent.

Monitoring of the atmospheric ozone layer and natural ultraviolet radiation. Annual report 2010. NILU OR
This is an annual report describing the activities and main results of the monitoring programme ¿Monitoring of the atmospheric ozone layer and natural ultraviolet radiation¿ for 2010.
2010 was a year with generally high ozone values above Norway. A clear decrease in the ozone layer above Norway during the period 1979-1997 stopped after 1998 and the ozone layer above Norway seems now to have stabilized.

Atmospheric deposition of heavy metals in Norway. Nationwide survey 2010. NILU OR
The geographical distribution of atmospheric deposition of heavy metals in Norway was mapped in 2010 by analysis of moss samples from 464 sites all over the country. This report provides a presentation of the results and a comparison with data from a series of corresponding moss surveys starting 1977. The survey is part of an international program comprising large parts of Europe. The survey primarily concerns the ten metals of priority in the European program: vanadium, chromium, iron, nickel, copper, zinc, arsenic, cadmium, mercury, and lead. In addition data are reported for another 42 elements in the moss. The discussion of the obtained data mainly refers to contributions from air pollution. In addition influence from natural processes to the elemental composition of the moss and how it may influence the interpretation of the data is discussed.

On behalf of the Norwegian Ferroalloy Producers Research Association (FFF) NILU has assessed possible airborne emissions of HCB, PCB, and PCDD/F from Norwegian silicon and ferrosilicon production.
The report concludes with that the Norwegian silicon and ferrosilicon melting process does most certainly not lead to a 'de novo' formation of organochlorines. The report summaries all performed emission measurements. It states that, even in worst case, the annual contribution from Norwegian silicon and ferrosilicon production does not exceed one percent of the total annual load. Thus the contribution is regarded as negligible.
