Volatile and persistent emissions from traffic and power production on Svalbard. VETAPOS. NILU OR
Volatile organic compounds (VOC) including Benzene-Toluene-Xylene (BTX) related compounds were monitored in ambient air samples during Spring (April-Mai) and Autumn (October) 2010 as a follow-up of an earlier BTX ambient air monitoring program in 2007 (Reimann et al 2007) at the Research park in Longyearbyen (Forskningsparken). In addition, BTX related compounds were measured in 18 ¿headspace¿ samples above collected surface soil along snowmobile tracks in Longyeardalen, Adventdalen, Todalen as well as Sassendalen (Fredheim). In addition, during the 2010 VETAPOS in a parallel surface soil sampling campaign 18 samples were analysed for 15 priority PAH compounds.

An ambient air pollution screening study was performed in Dhaka from 31 January - 15 February 2011. The main objective of the study was to gain an overview of the background concentrations and the spatial distribution of the air pollution in the Dhaka city area. Thorough ambient air quality data has not been collected in the city for some years. Results show relatively high concentrations for SO2, NO2, and O3, with PM concentrations alarmingly high. PM concentrations could be attributed to local sources (predominantly brick Kilns and traffic), as well as regional influences (haze clouds) during the winter season which were compared to satellite AOD data.

SK-1531 Dispersion calculations and HSE evaluation. NILU OR
Norwegian Institute for Air Research (NILU) has performed dispersion calculations of emissions to air from stack SK-1531 at Mongstad refinery. Dispersion of NH3, HCN, CO, CO2, NO2, SO2 and benzene is calculated and analyzed. NILU has also evaluated the calculated concentrations from a HSE point of view, including life time/degradation of the components. The calculated concentrations have been added to existing background concentrations at Mongstad and the calculated total concentrations have been compared to air quality guidelines and threshold values. None of the components investigated here exceed the threshold values. Emissions from SK-1531 is then considered not to represent a problem for the air quality at Mongstad

Assesment of wind, snow and seasalt. Hammerfest 2009-2010. NILU OR
NILU has made an assesment of windconditions, amount of snow and seasalt impact in Hammerfest. The assesment has been made on behalf of Statnett connected to a projected construction of power supply network.
