Kinetics of arsenate reduction by dissolved sulfide

Article Abstract:

Studies were held to see how reactions between arsenic and sulfide influenced water quality in arsenic-contaminated systems. Kinetics and reactions pathways of arsenate with sulfide were investigated. The article breaks down how the study took places and what its results were.

Arsenic mobilization by the dissimilatory Fe(III)-reducing bacterium Shewanella alga BrY

Article Abstract:

Lake Coeur d'Alene, Idaho is contaminated by run off from local silver and lead mining. Researchers studied deposition of iron, arsenic, and other minerals. Core samples taken from the lake showed a consistent deposition. Lead, and zinc deposited low in the sediment. Arsenic remained at the sediment-water interface. This implied that some means was keeping arsenic from setting out. Shewanella alga, is known to be able to mobilize arsenic. Researchers studied this process to see if the bacteria used HFO (ferric oxide) as part of the process of reducing arsenic. For their experiment, they used synthetic scorodite (a FE-As mineral) to confirm their hypothesis.
