Latest Eutrophication Stories

Among the six categories included in the Life-Sciences Network is one featuring the latest scientific publications in the Environment Sciences. The most recently published articles deal with environmental issues of water bodies including the Danshui River in Taiwan, the Mediterranean Sea and the Three Kettle Lakes in Southwest Michigan, USA. (PRWEB) October 10, 2011 The Environment Sciences category of the Magazine currently contains nearly 33,000 articles. A great part of these...

Changes in the ratio of nitrate to phosphorus in the oceans off the coasts of Korea and Japan caused by atmospheric and riverine pollutants may influence the makeup of marine plants and influence marine ecology, according to researchers from Korea and the U. S. "Normally in a marine environment nitrate is the limiting factor, but increased nitrate in the ocean can spur growth and create a situation where phosphorus becomes the nutrient in short supply," says Raymond G. Najjar, professor of...

A U.S. Department of Agriculture (USDA) soil scientist in Colorado is helping farmers grow crops with less nitrogen-based fertilizer. The fertilizers are a major reason why agriculture is a significant source of both greenhouse gas emissions and pollution in estuaries like the Gulf of Mexico and the Chesapeake Bay. If growers apply too little fertilizer, it reduces crop yields. But if they apply too much, the excess can be released into the atmosphere as nitrous oxide or leach into...

  For the first time, researchers at the University of California, Davis, have demonstrated that forest trees have the ability to tap into nitrogen found in rocks, boosting the trees' growth and their ability to pull more carbon dioxide from the atmosphere. Given that carbon dioxide is the most important climate-change gas, the nitrogen in rocks could significantly affect how rapidly the earth will warm in the future, the researchers say. They report their findings in the Sept. 1 issue...

Billions of people owe their lives to nitrogen fertilizers — a pillar of the fabled Green Revolution in agriculture that averted global famine in the 20th century — but few are aware that nitrogen pollution from fertilizers and other sources has become a major environmental problem that threatens human health and welfare in multiple ways, a scientist said here today. "It's been said that nitrogen pollution is the biggest environmental disaster that nobody has heard of," Alan Townsend,...

American University researcher focusing on Guam to document process in actionNitrogen pollution in our coastal ecosystems, the result of widespread use of synthetic agricultural fertilizers and of human sewage, leads to decreased water transparency, the loss of desirable fish species, and the emergence of toxic phytoplankton species"”such as the algae behind the renowned "red tides" that kill fish.The effects are particularly pronounced in the Gulf of Mexico and the Caribbean.A...

An international study published today warns that nitrogen pollution, resulting from industry and agriculture, is putting wildlife in Europe's at risk. More than 60 per cent of the EU's most important wildlife sites receive aerial nitrogen pollution inputs above sustainable levels.There is evidence of impacts on semi-natural grasslands, heathlands and forests across Europe. This threat is set to continue unless there is further action on emissions of polluting nitrogen gases.The study calls...

Reactive Nitrogen Causes Much Higher Climate-damaging Nitrous Oxide Emissions in European Forests than Previously Estimated by the IPCCReactive nitrogen compounds from agriculture, transport, and industry lead to increased emissions of the greenhouse gas nitrous oxide (N2O) from forests in Europe. Nitrous oxide emission from forest soils is at least twice as high as estimated so far by the Intergovernmental Panel on Climate Change (IPCC). This is one of the key messages of the first study on...

Nitrogen is needed to feed a growing world population but pollutes air, soil and waterA major new study finds that nitrogen pollution is costing each person in Europe around £130 - £650 (€150 "“ €740 Euros) a year. The first European Nitrogen Assessment (ENA) is launched at a conference today in Edinburgh, Scotland.The study, carried out by 200 experts from 21 countries and 89 organizations, estimates that the annual cost of damage caused by nitrogen across Europe is...

The growing world population relies on the help of nitrogen for our food supply, yet its very use pollutes the air, soil and water.The first European Nitrogen Assessment (ENA), launched at a conference today, estimates that nitrogen pollution will cost Europe an annual of €70 to €320 billion ($100-$460 billion USD) in damages.It found that the nitrogen pollution contributes to climate change as well as biodiversity loss."Nearly, half the world's population depends on synthetic,...
