1. 1. Investigating the potential correlations between metal and metalloid concentrations and soil color : A Minor Field Study on the island province of Marinduque, Philippines

   University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

   Author : Ivana Pia Saric Söderholm; Erik Readwin; [2023]
   Keywords : Marinduque; Metal and Metalloid; Nix Pro 2 Color Sensor; Philippines; Soil color; X-Ray Fluorescence XRF ; Filippinerna; Jordfärg; Marinduque; Metall och Metalloid; Nix Pro 2 Color Sensor; Röntgenfluorescens XRF ;

   Abstract : This study was carried out as a bachelor's thesis at KTH Royal Institute of Technology during the spring of 2023, investigating the correlation between the color with the concentration of various metal and metalloids (MMs) in the soil of Marinduque, The Philippines. With a history of mineral exploitation, notably copper and gold, the island has faced persistent environmental challenges, exemplified by the catastrophic waste spills in 1993 and 1996 that contaminated the Boac and Mogpog Rivers.

3. 2. Sargassum digestate as fertiliser in Grenada

   University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

   Author : Lina Bengtsson; Theodor Halldin; [2023]
   Keywords : Sargassum; digestate; fertiliser; heavy metals; Sargassum; digestat; gödningsmedel; tungmetaller;

   Abstract : Surges of Sargassum have become more severe and at the time of writing the largest surge yet is set to hit the Caribbean islands, affecting tourism and marine life negatively. Tourism is Grenada’s single handedly largest economic sector, which is why it is important to research the use of Sargassum. READ MORE

4. 3. Spatial analysis of arsenic and fluoride mobilization in groundwater around Mount Meru, northern Tanzania

   University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

   Author : Henriette Nishimwe; [2023]
   Keywords : Arsenic; Fluoride; Groundwater; Mobilization; Mount Meru; Geochemical and Spatial Modelling; Arsenic; Fluoride; Groundwater; Mobilization; Mount Meru; Geochemical and Spatial Modelling;

   Abstract : In Tanzania, approximately 76% of the drinking water supplies is dependent on groundwater sources. However, the groundwater in north Tanzania is susceptible to contamination by arsenic and fluoride. This study examines the spatial analysis of arsenic and fluoride mobilization in groundwater around Mount Meru, located in northern Tanzania. READ MORE

5. 4. Solubility of arsenic in untreated and ZVI-treated contaminated aquifer material

   University essay from SLU/Dept. of Soil and Environment

   Author : Oscar R. Davies; [2022]
   Keywords : Hjältevad; zerovalent iron; phosphate extraction; Oxalate extraction; Visual MINTEQ; geochemical modelling;

   Abstract : 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

6. 5. 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 geovetenskaper

   Author : Klara Skoog; [2022]
   Keywords : Bergslagen; Svecokarelian orogeny; metamorphism; arsenic; optical microscopy; electron microprobe; thermodynamic modelling; Bergslagen; Svecokarelska orogenesen; metamorfos; arsenik; optisk mikroskopering; elektron mikrosond; termodynamisk modellering;

   Abstract : 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
