For most living things, arsenic is a deadly poison, but new research shows that microorganisms are breathing arsenic in a large area of the Pacific Ocean. A University of Washington team has discovere...
Arsenic and phosphorus biogeochemistry in the ocean: Arsenic species as proxies for P-limitation
Arsenic and phosphorus biogeochemistry the ocean: Arsenic species proxies for P-limitation
2014/4/2
Arsenic and phosphorus are biochemically very similar, and hence arsenate (As5+) is toxic by interfering with the energy metabolism, in particular during P limitation. However, many phytoplankton deto...
Flooding and arsenic contamination: Influences on ecosystem structure and function in an Appalachian headwater stream
Flooding arsenic contamination ecosystem structure
2014/4/22
We investigated the influence of flooding and chronic arsenic contamination on ecosystem structure and
function in a headwater stream adjacent to an abandoned arsenic (As) mine using an upstream (ref...
