Arsenic contamination of drinking water poses serious health risks to millions of people worldwide. To reduce such risks, the United States Environmental Protection Agency recently lowered the Maximum Contaminant Level for arsenic in drinking water from 50 to 10μgL −1 . The majority of water systems requiring compliance are small systems that serve less than 10,000 people. Current technologies...
Several species of fern from the Pteris genus are able to accumulate extremely high concentrations of arsenic (As) in the fronds. We have conducted short-term unidirectional As influx and translocation experiments with 73As-radiolabeled arsenate, and found that the concentration-dependent influx of arsenate into roots was significantly larger in two of these As-hyperaccumulating species, Pteris vittata...
Edible plants enhanced with minerals were tested to determine whether these plants could be used as a new source of mineral dietary supplements that provide essential minerals in a more available form than current, inorganically based mineral supplements. A select cultivar of Brassica juncea was identified that can be cultivated under hydroponic conditions to contain high levels of nutritionally important...
