    • Abstract:
      Reports on the finding on the role of monomethylarsonous acid for arsenic methylation intermediate in human urine. Involvement of stepwise reduction of pentavalent to trivalent acid species; Arsenic speciation carried out using ion-pair chromatographic separation of arsenic compounds with hydride generation atomic fluoresence spectometry detection.
