  abstract: in most aquatic environments. Direct consumption and
  abstract: bioaccumulation from potable water are two pathways that can
  abstract: expose humans to these toidns which have been labeled as both
  abstract: systemic toxins and as potential carcinogens. Their toxicity
  abstract: and lipophilicity are a result of their degree of
  abstract: chlorination; thus dechlorination leads to detoxification.
  abstract: Current detection of these compounds is based on complicated
  abstract: instrumentation that is both expensive and requires technical
  abstract: expertise. Detoxification has been accomplished using
  abstract: certain biological organisms and chemical techniques. There
  abstract: is a need for a simple field-practical assay for water
  abstract: solvated chlorophenols that offers both sensitivity and
  abstract: selectivity. If water-solvated chlorophenols are detected,
  abstract: there is the need to dechlorinate, and thus detoxification,
  abstract: the more toxic chlorophenols, especially pentachlorophenol. A
  abstract: simple, field-practical assay for water-solvated
  abstract: chlorophenols based on fluorescent derivatization was
  abstract: developed. The water-solvated chlorophenols were derivatized
  abstract: and the derivatized complex was extracted from other
  abstract: impurities found in potable water. The fluorescent complex
  abstract: was bound on a reactive interface housed in a glass
  abstract: minicolumn and fluorescence was induced by ultraviolet
  abstract: radiation. This assay offered great sensitivity (O. Igg)
  abstract: and selectivity. All detection error was positive error
  abstract: which would minimize exposure to an unknown risk.
  abstract: Dechlorination of water-solvated pentachlorophenol was
  abstract: accomplished using three morphologically different ammonium-
  abstract: exchanged calcium montmorillonites. Ammonium-exchanged
  abstract: Nevalite montmorillonite (AENM) demonstrated the ability to
  abstract: dechlorinate water-solvated pentachlorophenol by 23% in 60
  abstract: hours. A second, better-characterized exchanged calcium
  abstract: montmorinonite, ammonium-exchanged calcium montmorillonite
  abstract: (AECM) demonstrated similar ability to dechlorinate
  abstract: pentachlorophenol in aqueous solution by 18.2% in 60 hours.
  abstract: Calcium montmorillonite was then propped with hydroxy
  abstract: aluminum, greatly increasing the interlaminar area.
  abstract: Ammonium-exchange of this propped clay greatly increased its
  abstract: dechlorination ability to 26.6%. Hydra attenuate, small
  abstract: fresh-water coelenterates which are sensitive to halogenated
  abstract: compounds such as pentachlorophenol, were used as a bioassay
  abstract: to evaluate if absorption and dechlorination of
  abstract: pentachlorophenol resulted in decreased toxicity. This
  abstract: bioassay demonstrated that two of the three clays were able
  abstract: to afford protection. in potable water. The fluorescent
  abstract: complex was bound on a reactive interface housed in a glass
  abstract: radiation. This assay offered great sensitivity (O. ltlg)
