    Keywords : NATURAL SCIENCES; NATURVETENSKAP; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; NATURVETENSKAP; TEKNIK OCH TEKNOLOGIER; NATURAL SCIENCES; ENGINEERING AND TECHNOLOGY; Chitosan Biopolymer; Characterization; Biodegradable; Arsenic V ; Uranium VI ; Adsorption; Isotherm; Kinetic model; Chitosan; Biopolymer; Karakterisering; Bionedbrytbar; arsenik V ; uran VI ; Adsorption; Isoterm; Kinetisk modell; Mark- och vattenteknik; Land and Water Resources Engineering;

    Abstract : In many countries over the world (including Sweden), metal toxicity in freshwater resources causes a severe drinking water quality problem and poses a threat to the environment and human health. Among the different toxic metals in the water resources of Sweden, arsenic and uranium are the biggest threats to health. READ MORE

  2. 2. Arsenic Geochemistry in the Alluvial Aquifers of West Bengal, India : Implications for targeting safe aquifers for sustainable drinking water supply

    Author : Ashis Biswas; Prosun Bhattacharya; Laurent Charlet; KTH; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; Bengal Basin; Groundwater; Arsenic; Redox processes; Competing ions; Sustainable drinking water Supply;

    Abstract : The natural occurrences of high (>10 μg/L) dissolved arsenic (As) in groundwater of Bengal Basin has put millions of people under the threat of chronic As exposure through drinking water. Present study has examined the processes that regulate As mobilization and its distribution in shallow aquifers and the potentiality of finding safe aquifers within shallow depth (. READ MORE

  3. 3. Arsenic Exposure Risk from Rice and Other Dietry Components in Rural Bengal

    Author : Dipti Halder; Prosun Bhattacharya; Mohammad Alauddin; KTH; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Rural Bengal; Arsenic; Rice and other dietary components; Total daily intake; Biomarkers; Risk assessment;

    Abstract : This study investigates the risk of arsenic (As) exposure from staple diet to the communities in rural Bengal, even when they have been supplied with As safe drinking water. The results indicate that average accumulation of As in rice grain increases with decrease of grain size [extra-long slender (ELS): 0.04 mg kg-1; long slender (LS): 0. READ MORE

  4. 4. Arsenic in Alluvial Aquifers in the Meghna Basin, Southeastern Bangladesh : Hydrogeological and Geochemical Characterisation

    Author : Md. Aziz Hasan; Prosun Bhattacharya; William Burgess; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Alluvial aquifer; groundwater; arsenic mobilisation; geology; Meghna basin; Bangladesh; Water engineering; Vattenteknik;

    Abstract :  Elevated levels of arsenic (As) in Bangladesh groundwater has emerged as a massive calamity exposing a large population to the risk of As toxicity from drinking water sources and agricultural products. Holocene alluvial aquifers in the delta- and flood-plains of the Ganges-Brahmaputra- Meghna (GBM) river systems are severely affected by high levels of As in groundwater. READ MORE

  5. 5. Sustainable Arsenic Mitigation A Strategy for Scaling-up Safe Water Access : A Strategy for Scaling-up Safe Water Access

    Author : Mohammed Hossain; Prosun Bhattacharya; Marinus Eric Donselaar; KTH; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Bangladesh; drinking water; arsenic mitigation; local tubewell driller; sediment color tool; low-manganese; Intermediate Deep aquifer; Land and Water Resources Engineering; Mark- och vattenteknik;

    Abstract : In rural Bangladesh, the drinking water supply is mostly dependent upon manually operated hand pumped tubewells, installed by the local community. The presence of natural arsenic (As) in groundwater and its wide scale occurrence has drastically reduced the safe water access across the country and put tens of millions of people under health risk.
