1. Remediation of per- and polyfluoroalkyl substances (PFAS) in contaminated water by sorption to pine- and spruce bark
University essay from Örebro universitet/Institutionen för naturvetenskap och teknikAbstract : PFAS are anthropogenic substances used in many different industrial operations and products because of their unique properties. Due to their negative impact on human health and environmental bioaccumulative characteristics different authorities have addressed the issue. In Sweden the limit is4 ng/L for four different PFAS in drinking water. READ MORE

2. In situ electrokinetic remediation of soil co-contaminated with trace elements and polycyclic aromatic hydrocarbons
University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurserAbstract : Sites contaminated with polycyclic aromatic hydrocarbons can be simultaneously contaminated with trace elements. Co-contaminated soil is considered a complex problem since inorganic and organic contaminants behave differently and thereby often require different remediation strategies. READ MORE

3. Solubility of arsenic in untreated and ZVI-treated contaminated aquifer material
University essay from SLU/Dept. of Soil and EnvironmentAbstract : Arsenic (As) is a toxic element to all life and exists in nature both naturally and anthropogenically. Naturally As contaminated soils are formed due to high geogenic background As concentrations which is released when bedrock is eroded. Asia is a continent with a high amount of naturally As contaminated soils and groundwater. READ MORE

4. Long-term Effect of Metallic Iron Sorbents on Arsenic Mobility in an Anoxic Aquifer : An assessment based on long-term column experiments
University essay from SLU/Dept. of Soil and EnvironmentAbstract : Zero valent iron (ZVI) sorbents have successfully remediated soils burdened with different groups of contaminants. When working to alleviate arsenic (As) contamination, the location-specific subsurface chemistry greatly affects the efficiency of the sorbents as it controls the speciation of As and the transformation of the ZVI, as well as the interaction between these (remediating mechanisms).

5. Geochemical tracing of Arsenic sources in groundwater at the remediated Storliden mine, Skellefte district
University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurserAbstract : The Swedish mining industry has changed from the historical situation with several smaller mines to the present situation with a few, bigger mines. This results in presence of abandoned mines around Sweden. Remediation of mines is regulated by legislation and the present demands are considerably higher than it was some decades ago. READ MORE
