摘要

Blaney and SenGupta(1)raise several interesting points regarding the release of arsenic from landfills through reductive processes. They argue that solid-phase arsenic in landfills is inherently unstable despite the strong adsorption of arsenic to iron(III)oxides(e.g.,2). They base these observations on our recent findings for the Coakley Landfill Superfund Site,a landfill exhibiting arsenic contamination(3). Our study,along with other recent studies(4-5),finds that reduction of arsenic-bearing iron oxides results in the release of arsenic from either the landfill(resulting in elevated arsenic concentrations in the landfill leachate)or from the surrounding rock formations.
