    Keywords : Arsenic; Hydrogeology; Drinking water; Data capture; Bangladesh; GeoGIS; Visualization; Sustainable mitigation; Arsenik; Hydrogeologi; Dricksvatten; Datainsamling; Bangladesh; GeoGIS; Visualisering; Hållbara åtgärder;

    Abstract : Arsenic-contaminated drinking water exposes ~230 million people worldwide to increased risks of several diseases and is considered one of the greatest threats to public health. In Bangladesh, arsenic-contaminated water has been declared the largest poisoning of a population in history, where 39 million people are exposed to arsenic levels above the WHO guidelines (>10 μg/L).

  3. 12. Geochemical tracing of Arsenic sources in groundwater at the remediated Storliden mine, Skellefte district

    University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Author : Matilda Edvardsson; [2021]
    Keywords : Arsenic; groundwater; Sulfide oxidation; Arsenopyrite; Storliden; remediation; Arsenik; grundvatten; sulfidoxidation; Arsenikkis; Storliden; efterbehandling;

    Abstract : 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

  4. 13. A STATISTICAL APPROACH FOR IDENTIFICATION OF CHEMICAL GROUPINGS OF ELEMENTS IN SWEDISH ROCKS WITH SPECIAL FOCUS ON ARSENIC AND SULPHUR

    University essay from Uppsala universitet/Statistiska institutionen

    Author : Erika Frank; [2021]
    Keywords : Bedrock; rock type; correlation; cluster analysis; multi-dimensional scaling; individual differences scaling; discriminant analysis;

    Abstract : Groundwater analyses have revealed high concentrations of the toxic element arsenic around Stockholm and Mälardalen, a problem that often is linked to high levels of arsenic in the bedrock and which could be escalated by the many construction projects in the same region. However, it is unknown what part of the bedrock is causing the contamination. READ MORE

  5. 14. Biochar-based thin-layer capping of contaminated sediment in Burefjärden, northern Sweden : Assessment of biochar mixed into four structural materials for preventing release of trace elements from sediment to water

    University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Author : Nathalie Pantzare; [2021]
    Keywords : biochar; contaminated sediment; remediation; thin-layer capping;

    Abstract : Coastal areas around the world have been recognized as largely impacted by anthropogenic activities resulting in pollution of marine sediments. In Sweden, surveys conducted along the coastline of the Bothnian Bay have identified a total area of about 29 km2 as fiber rich sediments. READ MORE

  6. 15. Modeling groundwater flow using COMSOL to understand the water cycle dynamics and climate change impacts for future groundwater availability in the Matlab region, Southeastern Bangladesh

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Oscar Vandromme; [2021]
    Keywords : Aquifer-Arsenic contamination-Climate change-Groundwater elevation-Model-Sustainability;

    Abstract : Arsenic contamination has been a growing concern for many countries, especially Bangladesh. In Bangladesh, one of the most arsenic-contaminated regions is Chandpur. In this study, groundwater data were analyzed in order to create models to improve knowledge on groundwater flow dynamic in a specific area of Chandpur called Matlab. READ MORE
