Boreal forest lakes suffer from 'aquatic osteoporosis,' Queen's-York research team suggests A new and insidious environmental threat has been detected in North American lakes by researchers from Queen's and York universities. Along with scientists from several Canadian government laboratories, the team has documented biological damage caused by declining levels of calcium in many temperate, soft-water lakes. Calling the phenomenon "aquatic osteoporosis," Queen's PhD candidate Adam Jeziorski,...

WASHINGTON, Aug. 12 /PRNewswire-USNewswire/ -- As part of the fifteenth settlement secured by the Justice Department and the Environmental Protection Agency to control harmful air pollution from coal-fired power plants, the owner and operator of a plant in St. Johns, Ariz., has agreed to install pollution controls at an estimated cost of $400 million to reduce harmful emissions and pay a $950,000 civil penalty. Today's settlement resolves alleged violations of the New Source Review...

By Niki Sullivan, The News Tribune, Tacoma, Wash. Jul. 29--A faulty batch of chemicals might have caused the pH level of Wapato Lake to plummet during an algae treatment Friday, suffocating large numbers of fish, according to the company hired to monitor water quality. Rob Plotnikoff, a senior scientist with Seattle water monitoring company Tetra Tech, told the Metro Parks board of commissioners Monday that the lake is safe now, but they'll have to wait for more information -- including...

By Tom Wanamaker, Watertown Daily Times, N.Y. Jul. 13--ALBANY -- Friday's federal appeals court ruling that struck down the Clean Air Interstate Rule has been roundly criticized by the Adirondack Council. "By striking down the Clean Air Interstate Rule, the court has left all of the Northeastern states vulnerable to acid rain and fine particles of smoke that damage people's lungs," said Scott Lorey, director of government relations for the Adirondack Council, a conservation advocacy...

By Debra McCown, Bristol Herald Courier, Va. Jul. 11--ABINGDON, Va. -- While a new coal-fired power plant under construction in Wise County will add another local pollution source, the permitting process for it has spurred emissions reductions at an existing power plant nearby. Appalachian Power's Clinch River Power Plant in Russell County, Va., must reduce its emissions after air-quality computer modeling showed potential for a problem, said company representatives and Virginia...

U.S. environmental scientists say they have created one of the most comprehensive databases on the effects of acid rainfall. Prior to enactment of the U.S. Clean Air Act, unhindered industrial emissions were released into the air across the nation, with many of the chemicals falling back to Earth in the form of acid rain. Although scientists have long known acid rain can severely decrease the diversity of plant and animal communities in fresh water lakes and ponds, little is known about...

Prior to the federal Clean Air Act, unhindered industrial emissions were released into the air throughout the Midwestern and Eastern United States for decades. Many of those harmful chemicals came right back down to earth in the form of acid rain, a chemical concoction that includes nitric and sulfuric acid. Researchers have long known that acid rain can severely decrease the diversity of plant and animal communities in fresh water lakes and ponds. However, little is known about how...

BEIJING -- China failed to rein in two main pollution indicators in the first half of the year as soaring energy use and lax environmental controls thwarted policies to clean foul water and skies, the government said on Wednesday. "Environmental protection and economic development are not proceeding in unison," the China Environment News, the official paper of the State Environmental Protection Administration (SEPA), wrote in an editorial. China has set a goal of cutting pollution output by...

BEIJING (Reuters) - Acid rain caused by sulphur dioxide spewed from factories and power plants affected a third of China's vast land mass last year, posing a threat to food safety, Xinhua news agency said citing a parliamentary report. More than half of the 696 cities and counties monitored had suffered acid rain, in some cases on a daily basis, according to a pollution inspection report submitted to the standing committee of parliament, the official agency said. "Increased sulphur...

BEIJING -- China's environmental chief has blamed fraudulent environmental approvals and patchy installation of control equipment for rises in pollution, state media reported on Monday. Pollution discharges increased in 17 provinces in the first half, despite a government pledge to cut emissions 2 percent by the end of the year, the Shanghai Daily newspaper quoted Zhou Shengxian, director of the State Environmental Protection Administration (SEPA), as saying. "Fraud in project approval was...

Acid Rain
2013-04-01 10:21:17

Acid rain is any form of precipitation that is unusually acidic, meaning that is possesses high levels of hydrogen ions. It can have harmful effects on aquatic animals, plants, and infrastructure. Acid rain is caused by emissions of sulfur dioxide and nitrogen oxide, which react with the water molecules within the atmosphere to produce acids. Nitrogen oxides can be produced naturally by lightening strikes. Sulfur dioxide can be produced naturally by volcanic eruptions. The chemicals that are...

Rain is a type of liquid precipitation. It is defined as condensation of atmospheric water vapor that forms into drops that become heavy enough to fall, and often making it to the surface. Rain is the primary source of most of the fresh water in the world. Rain provides suitable conditions for diverse ecosystems, water for power sources and for crop irrigation. Not all rain reaches the surface. Some rain evaporates as it falls, especially through dry air. This type of rainfall is known as...
