An international group of scientists is renewing calls for policymakers to reduce both nitrogen and phosphorus when attempting to alleviate eutrophication "“ or nutrient pollution problems "“ in fresh and coastal waters. In the February 20 edition of Science, the researchers argue that dual-nutrient reduction strategies are likely to be more successful due to complex interactions between nitrogen and phosphorus in fresh and coastal water ecosystems."If the overall goal of nutrient...

So far environmental protection of the Baltic Sea has not been successful, even though a wealth of research information exists to support such protection. The joint European Baltic Sea research program (BONUS) is aiming to study which social factors influence the success of protective measures. Particular attention is being paid to the prevention of the eutrophication of the Baltic Sea. "The background to this research project is the idea that social factors rather than a lack of scientific...

Scientists have found lichens can give insight into nitrogen air pollution effects on Sierra Nevada and San Bernardino mountain ecosystems, and protecting them provides safeguards for less sensitive species. Their findings are presented this month in the international journal Environmental Pollution and are significant because nitrogen from air pollution causes detrimental chemical and biological effects to terrestrial and aquatic ecosystems. Other harmful effects include elevated nitrate...

Residents in and around Annapolis, Md., say that 100,000 Atlantic Menhaden died this week because of too much algae in Chesapeake Bay. Chesapeake Bay Foundation official Bill Goldsboro said an overabundance of algae in area waters led to the sudden deaths of hundreds of thousands of the filter-feeding fish, WUSA in Washington said Wednesday. "It drew all the oxygen out of the water and the fish kill resulted," Goldsboro said. Goldsboro blamed the sudden increase in algae on a dramatic...

U.S. and Swedish research suggests the number of dead zones in the world's oceans has increased by a third since 1995. Robert Diaz of the Virginia Institute of Marine Science at the College of William and Mary said dead zones -- areas of the ocean with too little oxygen to support most marine life -- "rank with overfishing, habitat loss and harmful algal blooms as global environmental problems." Agricultural fertilizers are one of the key causes of the dead zones, the Virginia Institute of...

By PAMELA WOOD Staff Writer There are two dreaded words that pretty much sum up all thats wrong with the Chesapeake Bay: dead zone. Though scientists say the term is something of a misnomer, it conjures a relatively accurate picture of whats going on below the surface of the bay. The dead zone is a vast stretch of oxygen-deprived water that cant support fish, crabs, shellfish or even little worms. The root cause of the dead zone is nitrogen and phosphorus pollution that comes washing off...

"But if you destroy our water, if we lose it, if we ruin it, if we don't conserve it, if we aren't careful with it, we'll lose our cities....
