1. Distribution and transport of microplastics and metals in sewage sludge-amended agricultural soil : a Comparative study between microplastics copper, cadmium, and nickel
University essay from SLU/Dept. of Soil and EnvironmentAbstract : This thesis investigated the vertical transport of microplastics and metals in agricultural soil after sewage sludge application. Sewage sludge is commonly used in agriculture for adding nutrients and carbon to improve the soil quality. READ MORE

2. The Effects of Depth and Hydrological Connectivity on Heavy Metal Loading in Riparian Zones
University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskapAbstract : The area between a stream and land is known as a riparian zone. These zones are highly dynamic whichcarry and accumulate heavy metals and environmental contaminants. Discrete Riparian Input Zones(DRIPs) are a subset of such zones that carry concentrated amounts of water into streams at discrete points. READ MORE

3. Chemical Stabilization of Arsenic in Contaminated Soil under Low Redox Conditions
University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurserAbstract : Remediation techniques for arsenic contaminated soil have previously focused mostly on the surface soil layers where aerobic conditions are prevalent. In this master thesis, chemical stabilization by adding zero-valent iron (Fe(0)) and calcium oxide (CaO) to an arsenic-contaminated soil under low redox conditions have been studied through up-flow percolation tests.

5. Mineralogical speciation of sulfur in acid sulfate soils from Luleå, Sweden
University essay from Luleå tekniska universitet/Geovetenskap och miljöteknikAbstract : Marine sulfide – bearing sediments that oxidize when in contact with oxygen and leach outelements in high concentrations to small watercourses have been a problem for many years allover the world especially around the Bothnian Bay. The purpose of this study was to furtherinvestigate the sulfur mineralogy present in acid sulfate soils in the area of Luleå, Sweden. READ MORE
