Study reveals scale of nitrogen's effect on people and ecosystems. It's no secret that China is faced with some of the world's worst pollution. Until now, however, information on the magnitude, scope and impacts of a major contributor to that pollution — human-caused nitrogen emissions — was lacking. A new study co-authored by Stanford Woods Institute biologist Peter Vitousek reveals that amounts of nitrogen (from industry, cars and fertilizer) deposited on land and water in...

'High microcystin concentrations occur only at low nitrogen-to-phosphorus ratios in nutrient-rich Canadian lakes' Nutrient pollution, one of the greatest threats to our freshwater resources, is responsible for the algal blooms that blanket our lakes and waterways in summer months. Large blooms of cyanobacteria ('blue green algae') can cause fish kills, increase the cost of drinking water treatment, devalue shoreline properties, and pose health risks to people, pets, and wildlife. A new...

Study measures oysters' capacity to filter ag and urban runoff in the Chesapeake Bay Chronic water quality problems caused by agricultural and urban runoff, municipal wastewater, and atmospheric deposition from the burning of fossil fuels leads to oxygen depletion, loss of biodiversity, and harmful algal blooms. This nutrient pollution is prevalent in many coastal marine and estuarine ecosystems worldwide. Chesapeake Bay is the largest estuary in North America and although many efforts have...

NASHVILLE, N.C., Jan. 21, 2011 /PRNewswire/ -- According to opponents of the project, locating the proposed Sanderson Farms chicken slaughterhouse in Nash County likely will make it more difficult for the area to continue to grow and recruit cleaner, greener industries. Current law imposes fixed caps or limits on the amount of nutrients in the Tar-Pamlico and Neuse River Basins. "This facility, and the hundreds of new chicken houses required to supply it, ultimately will have long-term...

Elevated concentrations of nitrogen and phosphorus, nutrients that can negatively impact aquatic ecosystems and human health, have remained the same or increased in many streams and aquifers across the Nation since the early 1990's, according to a new national study by the U.S. Geological Survey. "This USGS report provides the most comprehensive national-scale assessment to date of nitrogen and phosphorus in our streams and groundwater," said Marcia McNutt, USGS Director. "For years we have...

Study suggests pollution reductions could help restoration efforts A new study to be published in the academic journal Reviews in Fisheries Science recommends that efforts to restore the endangered California delta smelt and other declining pelagic fish should more sharply focus on reducing nutrient pollution to the species' native waters. The research indicates these fish populations would greatly benefit from reductions in the amount of nitrogen flowing into the Sacramento-San Joaquin...
