Heavy metals at Xstrata. Assessment of measured concentration level. NILU OR

Tønnesen, D.

NILU has done an analysis of heavy metal concentrations measured at Xstrata, Kristiansand. Through a simplified dispersion scheme, the measured concentrations have been converted to emissions. These have been compared to the reported emissions from Xstrata. The reported emissions and the measured concentrations are in agreement.

Evaluation of new data sources for improving the estimation of background concentrations in Norway. NILU OR

Schneider, P.; Obracaj, A.

A previous report (OR 68/2011) described a geostatistical methodology developed for creating a consistent dataset of background concentrations of NO2, O3, PM10, and PM2.5 in Norway, that are representative of a typical year. The resulting dataset has a resolution of 0.1 degrees by 0.1 degrees and is available at hourly temporal resolution. Based on this existing methodology, this study reports on the evaluation of new data sources as a means of improving such estimates of background concentrations. The potential of satellite-derived NO2 data is evaluated for guiding the geostatistics-based spatial interpolation procedure of NO2 station data in Norway. Furthermore, the output from a high-resolution atmospheric model was tested with respect to its capability of improving the spatial and temporal characterization of background concentrations. Finally, an online web mapping system was developed to make the project results easily accessible and to provide basic data analysis and visualization routines for the public.

Measurement data. July 2011 - June 2012. Environmental monitoring of emissions to air from Snøhvit-Hammerfest LNG. NILU OR

Hak, C.

Statoil assigned NILU - Norwegian Institute for Air Research to carry out a programme on 'Environmental monitoring of emissions to air from the Snøhvit LNG facility'. The project started on 1 February 2006. This report summarises the results of the measurement programme from 1 July 2011 to 30 June 2012. It involves the measurement of meteorological parameters on Melkøya and Fuglenesodden. Air quality parameters were measured at Fuglenesodden. Precipitation samples taken at Forsøl and Kargeneset were analysed for PAHs, inorganic ions, heavy metals and mercury. The current air quality standards are met for all compounds.
