  2. 1. 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 : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; 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.

  4. 2. Hydrogeological and geochemical assessment of aquifer systems with geogenic arsenic in Southeastern Bangladesh : Targeting low arsenic aquifers for safe drinking water supplies in Matlab

    Author : Mattias von Brömssen; Prosun Bhattacharya; David Polya; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Arsenic; Bangladesh; drinking water; groundwater; sustainability; geochemistry; hydrogeology; modelling;

    Abstract : Naturally occurring arsenic (As) in Holocene aquifers in Bangladesh have undermined a long success of supplying the population with safe drinking water. Arsenic is mobilised in reducing environments through reductive dissolution of Fe(III)-oxyhydroxides. READ MORE

  5. 3. Prenatal Arsenic Exposure and Consequences for Pregnancy Outcome and Infant Health : Epidemiological Studies in Bangladesh

    Author : Anisur Rahman; Lars-Åke Persson; Eva-Charlotte Ekström; Marie Vahter; Gunnar Nordberg; Uppsala universitet; []
    Keywords : arsenic; groundwater; foetal loss; birth weight; lower respiratory tract infection; diarrhoeal diseases; infant mortality; cohort; Bangladesh; MEDICINE; MEDICIN; Medicine; medicin;

    Abstract : The aim of this thesis was to analyse possible effects of prenatal arsenic exposure on foetal and infant health. The setting is Bangladesh, where two cohorts were studied, both part of a health and demographic surveillance system in Matlab. READ MORE

  6. 4. Epidemiological and Spatial Association between Arsenic Exposure via Drinking Water and Morbidity and Mortality : Population based studies in rural Bangladesh

    Author : Nazmul Sohel; Lars Åke Persson; Marie Vahter; Pavlos Kanaroglou; Gunnar Nordberg; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Arsenic; tube-well; skin lesion; adult mortality; foetal loss; infant death; cohort; spatial model; Bangladesh; Epidemiology; Epidemiologi; International Health; Internationell hälsa;

    Abstract : The overall aim of this thesis is to evaluate the risk for increased morbidity and mortality due to long-term arsenic exposure via drinking water by use of epidemiological and spatial approaches in studies performed in Matlab, Bangladesh. A total of 166,934 individuals aged 4 years and above were screened for skin lesions in 2002-2003. READ MORE

  7. 5. Arsenic in tubewell water of Bangladesh and approaches for sustainable mitigation

    Author : Md. Jakariya; Prosun Bhattacharya; Jan Hoinkis; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Tubewell; Arsenic; field test kit; groundwater; sediment colour; local drillers; safe aquifer; people’s initiatives; Participatory GIS PGIS ; Water in nature and society; Vatten i natur och samhälle;

    Abstract : There is an urgent need for Bangladesh to identify the arsenic (As) contaminated tubewells (TWs) in order to assess the health risks and initiate appropriate mitigation measures. This involves testing water in millions of TWs and raising community awareness about the health problems related to chronic As exposure from drinking water, and providing alternative safe water option for the exposed population of the country.
