For decades, many residents of Eastern Oregon’s Morrow and Umatilla counties have relied on well water contaminated by nitrates, chemicals linked to cancers and thyroid disease — and especially ...

In a remote corner of eastern Oregon, families who have long depended on private wells are discovering that the water beneath ...

Researchers from Tokyo Metropolitan University have revealed how a catalyst in a promising chemical reaction for industry ...

Exploitation of microbially mediated reduction of redox-sensitive metals has been proposed as a promising strategy to remediate metal-contaminated subsurface environments in situ (Valls and de Lorenzo ...

A new study provides new insights to demonstrate that multiple wetlands or 'wetland complexes' within a watershed are extremely effective at reducing harmful nitrate in rivers and streams. These ...

Researchers from the Research Center for Eco-Environmental Sciences (RCEES) of the Chinese Academy of Sciences have developed ...

The internal transformations of nitrogen in terrestrial ecosystems exert strong controls over nitrogen availability to net primary productivity, nitrate leaching into groundwater, and emissions of ...

WAVERLY — A new bioreactor will reduce nitrates in tile water draining off Tom Manson's corn field just off Highway 63 northeast of Waverly. Sampling tile water before it flows into the bioreactor and ...

Researchers discovered that copper oxide catalysts form metallic copper mid-reaction, triggering a dramatic boost in ammonia output. The insight offers a roadmap for designing cleaner, more efficient ...

Substantial rates of nitrate reduction could be achieved with a reconstituted system from spinach leaves containing supernatant, mitochondria, NAD+, oxaloacetate (OAA), and an oxidizable substrate.

Recent studies show that nitrate and nitrite are physiologically recycled in blood and tissue to form NO and other bioactive nitrogen oxides. Thus, they should be viewed as storage pools for NO-like ...

Zinc-nitrate batteries are a type of non-rechargeable energy storage technology that uses the redox potential difference between zinc and nitrate ions to store and release electrical energy. A ...
