American University researcher focusing on Guam to document process in action Nitrogen 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 study...

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 IPCC Reactive 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 water A major new study finds that nitrogen pollution is costing each person in Europe around £130 - £650 (&eur;150 "“ &eur;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...

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 &eur;70 to &eur;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,...

Shallow disk injection found to be economically sound and environmentally safe, a technique that could help reduce nutrient runoff into the Chesapeake Bay Recycling manure is an important practice, especially for large livestock producers. Manure can be used as fertilizer to aid in crop production, aiding livestock producers that grow their own feed crops. While manure does provide a rich nutrient source for crops, it also can contribute to nutrient leaching and runoff. This can contaminate...

People who want to eat healthy and live sustainably have a new way to measure their impact on the environment: a Web-based tool that calculates an individual's "nitrogen footprint." The device was created by University of Virginia environmental scientist James N. Galloway; Allison Leach, a staff research assistant at U.Va.; and colleagues from the Netherlands and the University of Maryland. The calculator is a project of the International Nitrogen Initiative, a global network of scientists...

Recalculating the global use of phosphorous, a fertilizer linchpin of modern agriculture, a team of researchers warns that the world's stocks may soon be in short supply and that overuse in the industrialized world has become a leading cause of the pollution of lakes, rivers and streams. Writing in the Feb. 14 edition of the journal Environmental Research Letters, Stephen Carpenter of the University of Wisconsin-Madison and Elena Bennett of McGill University report that the human use of...

Continued eutrophication of the Baltic Sea, combined with an ever thinner ozone layer, is favoring the toxic cyanobacterium Nodularia spumigena, reveals research from the University of Gothenburg, Sweden. "There are several species of cyanobacteria, or blue-green algae, that can form surface blooms in the Baltic Sea," explains Malin Mohlin from the University of Gothenburg's Department of Marine Ecology. "Which species ends up dominating a bloom depends partly on how they deal with an...

Every person emits the equivalent of approximately two tons of carbon dioxide a year from the time food is produced to when the human body excretes it, representing more than 20% of total yearly emissions. That is what a study by the Universidad de Almería says, confirming for the first time that human excrements contribute to water pollution, primarily with nitrogen and phosphorus. A team of researchers from the Universidad de Almería (UAL) has estimated...
