1. 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).

2. Geochemical processes in mine waste subjected to a changing chemical environment: Fe speciation in leachate water from column experiments
University essay from Luleå tekniska universitet/Geovetenskap och miljöteknikAbstract : Oxidation of sulfidic mine waste is of significant environmental concern due to the consequent formation of acid rock drainage (ARD), deteriorating the water quality of natural water systems. Iron (Fe) and sulfur (S) are two major redox elements involved in these reactions and typically the major redox-sensitive elements (whose solubility, speciation, and mobility are affected by pH and Eh) in water affected by ARD.

3. Årstidsdynamik för kvicksilver i ett sövattensediment
University essay from SLU/Dept. of Forest Ecology and ManagementAbstract : The limit for mercury in fish, set by health authorities, is exceeded in about half of the lakes in Sweden. Methyl mercury (MeHg) is the most toxic form of mercury and accumulates in fish. READ MORE
