Popis: Monitoring was performed in the Nalunaq Gold Mine area, Nanortalik municipality, South Greenland during 20-26 August 2004. This was eight months after the first shipment of ore. Samples were collected at four marine stations in the Kirkespir Bay, Arctic char were sampled in the Kirkespir River, and lichens were collected at 20 stations in the Kirkespir Valley. Samples were analysed for 10 elements with an ICP-MS. Concentrations of Zn, Cu, Cr, As and Co were elevated 3-9 times compared to background concentrations found prior to mine start. The increased level of contamination in the local area is moderate compared to contaminations found around closed mines in Greenland, i.e. Maarmorilik, Ivittuut and Mestersvig Monitoring was performed in the Nalunaq Gold Mine area, Nanortalik mu-nicipality, South Greenland during 20-26 August 2004.
