  • Rapid on‐site separation of as(III) and as(V) in waters using a disposable thiol‐modified sand cartridge

    The rapid redox transformation of arsenic (As) species in waters presents a great environmental challenge in accurate determination of its concentration and toxicity. The motivation for our study is therefore to develop a method for rapid on‐site separation of As(V) and As(III) in various aqueous matrices. We synthesized a thiol‐modified sand (T‐sand), which selectively removed As(III) but did ...

  • Arsenic from community water fluoridation: quantifying the effect

    Community water fluoridation is a WHO recommended strategy to prevent dental carries. One debated concern is that hydrofluorosilicic acid, used to fluoridate water, contains arsenic and poses a health risk. This study was undertaken to determine if fluoridation contributes to arsenic in drinking water, to estimate the amount of additional arsenic associated with fluoridation, and compare this ...
