  • Arsenic Exposure and Childhood CancerA Systematic Review of the Literature

    The literature on environmental arsenic exposure and childhood cancer risk comprises 1) studies seeking childhood cancers among arsenic-exposed populations, 2) studies seeking arsenic exposure among childhood cancer cases, and 3) studies seeking associations in populations with both arsenic exposures and childhood cancer cases. No skin cancers were found in dermal examinations of over 25,000 ...

  • Characteristics of arsenate removal from water by metal-organic frameworks (MOFs)

    Contamination of arsenic in groundwater and surface water occurs frequently across the globe, requiring an effective purification technology. Among the common technologies, the adsorption method is widely used for the merits of low cost and easy operation. Nevertheless, the development of efficient adsorbents remains one of the central challenges in this field. In this article, one kind of ...

  • Arsenic removal using novel combined Fe/Mn adsorbent modified with silica

    Arsenic pollution has become a dominant environmental concern in recent years. Various techniques for arsenic removal from water have been developed. However, these techniques efficiently remove arsenic from drinking water but require toxic and expensive chemicals and generate a large amount of exhaust sludge, which is not always regenerable. In this study a novel Fe-Mn-Si oxide material was ...

  • Optimisation of sugar cane activated carbon for arsenic(V) and arsenic(III) removal from water

    This paper addresses the development of low-cost adsorbents for removal of arsenic from water in support of mitigation programmes in low and middle income countries. Activated carbon (AC) is a well established water treatment technology, but has high cost and low selectivity in respect of arsenic. AC made from agricultural by-products is a low-cost alternative to coal-based AC. In this study, ...

  • Winter exposure assessment of copper, zinc and arsenic in drinking water of inhabitants in Beijing, China

    Human exposure to Cu, Zn and As from drinking water in Beijing, China was estimated in winter. Cu, Zn and As were detected at 6.1, 400 and 0.6 µg/L on average in stagnant water, significantly different from those in the actually ingested boiled tap water, 5.1, 130 and 2.4 µg/L, respectively. Daily intake of Cu, Zn and As from drinking water was 0.8%, 7.7% and 28.5% of the minimum for adults ...
