1. Petrography and Thermodynamic Modelling of Svecofennian Arsenic-bearing Metasupracrustal Rocks in the Arlanda Area, West-Central Fennoscandian Shield
University essay from Uppsala universitet/Institutionen för geovetenskaperAbstract : The Arlanda area is a construction intensive area facing problems with risk of leaching of arsenic (As) from the bedrock to surface- and groundwater. Construction projects in the area have had problems with high levels of As in the bedrock and the risk of leaching increases through processing of aggregates and blasting of the bedrock. READ MORE
