Deposition of major inorganic compounds in Norway 2007-2011. NILU OR
The total deposition of sulphur and nitrogen compounds in Norway during the period 2007-2011 has been estimated on the basis of available measurement data for concentrations and precipitation. Deposition of non-marine base cations is also estimated. Results are compared with previous estimates for 2002-2006.

Possible future petroleum activity around Jan Mayen. Consequences of emissions to air. NILU OR
Norwegian Institute for Air Research (NILU), Norwegian Institute for Water Research (NIVA) and the Norwegian Institute for Nature Research (NINA) have concidered the effects on the environment of emissions of NOx, SO2 and particulate matter into the air from any future petroleum activity in the waters around Jan Mayen. It is estimated deposition of nitrogen, sulfur and particulates - also formation of ozone is calculated. It is also considered what effect it has on nature. Calculations indicate that emissions most likely will not lead to negative effects on vegetation and fauna of the terrestrial impact area.

Indoor air quality at Life Technologies AS. Measurement of particulate matter. NILU OR
NILU - Norwegian Institute for Air Research has carried out sampling of suspended particles at Life Technologies AS (formerly Invitrogen Dynal AS) in Lillestrøm. The sampling took place at three locations in the production area of the company in the period 31 January ¿ 28 February 2012. Previous investigations of similar kind have been carried out in 2007 and 2010.
The results of the present investigation showed that all of the measured particle concentrations were well below the norms from Arbeidstilsynet. The highest PM2.5 concentration observed was 14.5 µg/m3 during daytime in NIT-280 (50 l reactor), which is clearly below the norm recommended by Norwegian Public Health Institute. None of the PM samples taken at Life Technologies AS showed a value exceeding the company¿s OEL for Dynabeads.

Ambient air quality in Abu Dhabi. 2011 annual report. NILU OR
This Annual Report has been based on data from ten air quality monitoring stations operated in the Emirate of Abu Dhabi during 2011. The data have been ¿cleaned¿ and prepared as a basis for the statistics presented in this report. Air pollution in Abu Dhabi is dominated by suspended particles in the air. One of the main sources is linked to dust from the desert areas and to the occurrence of sand storms. Air Quality limit values for PM10 were exceeded at all monitoring sites in Abu Dhabi in 2011.
Limit values for 8-hour average ozone concentrations were also exceeded at all stations. Limit values for SO2, NO2 and CO were not exceeded in Abu Dhabi Emirate during 2011.
