  2. 16. Spatial variability of geogenic contaminants in drinking water sources : Insights into hydrogeological controls, geospatial data for safe water supply and groundwater resource management

    Author : J. Ijumulana; Prosun Bhattacharya; Felix Mtalo; Steve W. Lyon; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Drinking water; geogenic contaminants; potentially toxic elements; fluoride; spatial analysis; spatial variability; Tanzania; Land and Water Resources Engineering; Mark- och vattenteknik;

    Abstract : The presence of geogenic contaminants in drinking water is a major health concern in many parts of the world. The interaction of groundwater with different rock types and sediments in the natural geochemical environment play an important role in controlling their mobility. READ MORE

  4. 17. Hydrogeochemistry of arsenic, fluoride, and other trace elements in groundwater in northern Tanzania : Occurrence, distribution, and impacts on drinking water quality

    Author : Fanuel Josephat Ligate; Prosun Bhattacharya; Felix W Mtalo; Jyoti Prakash Maity; Joyanto Routh; KTH; []
    Keywords : Arsenic; Fluoride; Groundwater; Lake Victoria basin; Risk assessment; Sanya alluvial plain; Tanzania.; Aseniki; Bonde la Ziwa Victoria; Floridi; Maji yaliyopo ardhini; Tanzania; Tathmini ya hatari; Uwanda wa Aluvia ya Sanya.; Arsenik; Fluorid; Grundvatten; Viktoriasjön; Riskbedömning; Sanya alluvial slätt; Tanzania.; Mark- och vattenteknik; Land and Water Resources Engineering;

    Abstract : The occurrence of arsenic (As), fluoride (F-), and other trace elements (TEs) with potential toxicity in groundwater is a global environmental concern. According to the National water resource mapping database, about 76 % of the drinking water supply in Tanzania is abstracted from groundwater sources. READ MORE

  5. 18. Soil Remediation and Sustainable Development : Creating Appropriate Solutions for Marginalized Regions

    Author : Henrik Haller; Anders Jonsson; Mittuniversitetet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : The scope of this doctoral thesis is appropriate soil remediation methods for marginalized regions that go beyond pollution reduction targets and include strategies to support sustainable development. Contaminated soil from industrial or agricultural activities poses potential health threats to animals and humans and also threatens economic systems by making land unsuitable for agriculture and other economic purposes.

  6. 19. Urban impact on water bodies in the Luleå area, northern Sweden

    Author : Ralf Rentz; Luleå tekniska universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Applied Geology; Tillämpad geologi;

    Abstract : Anthropogenic activities change the quality of urban waters and sediments. The aim of this study was to describe and quantify pollution from different point sources in Luleå, northern Sweden. READ MORE

  7. 20. Polychlorinated biphenyls (PCB) in a river ecosystem

    Author : Gudrun Bremle; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Hydrobiology; dredging; landfill; cleanup; remedial action; air; fish; sediment; Persistent organic pollutants; freshwater; marine biology; aquatic ecology; limnology; Marinbiologi; limnologi; akvatisk ekologi;

    Abstract : Atmospheric deposition is one source of persistent pollutants such as polychlorinated biphenyls (PCB) in aquatic environments. Other point sources can also contribute to the PCB loadings in the water. READ MORE
