| Summary: | NILU has updated the model calculations for a planned aluminium smelter at Somastadagerdi The work is based on earlier investigations in the area, and on meteorological measurements done by the Icelandic MeteorologicalOffice in Reykjavik (IMO). Two alternatives for the smelter’s production of aluminium were considered: 280,000 and 420,000 tons of aluminium per year. In addition to this, emissions from an anode-baking furnace for the smelter have been analysed. The following parameters have been estimated: SO2, PM10, and PAH (yearly and winter season); Gaseous fluorides (growing season); SO2 (24 hour average, 98 and 99.2 percentile); PM10 (24 hour averages, 98 percentile and 90.4 percentile); SO2 (Hourly averages, 99.7 percentile); Study of unfavourable dispersion conditions.
