In the first effort to estimate the overall impact of a city´s urban forest on concentrations of fine particulate pollution (particulate matter less than 2.5 microns, or PM2.5), a U.S. Forest Service and Davey Institute study found that urban trees and forests are saving an average of one life every year per city. In New York City, trees save an average of eight lives every year. Fine particulate air pollution has serious health effects, including premature mortality, pulmonary...

Taking part in the largest U.S. air quality field project in decades, the National Center for Atmospheric Research is working with partners to study pollution in the Southeast. The study looks at the impact of chemical reactions occurring between human-related pollution and volatile organic compounds emitted from vegetation. Boulder, CO (PRWEB) June 19, 2013 Taking part in the largest U.S. air quality field project in decades, the National Center for Atmospheric Research (NCAR) is working...

Sulfur Aerosol Particles And Climate Change
2013-05-15 04:51:08

Brett Smith for redOrbit.com - Your Universe Online A new study on cloud formation shows that climate change models may have underestimated the cooling effect of sulfur aerosol particles in the atmosphere. These aerosols mitigate greenhouse gases by reflecting sunlight. They also act as seeds for cloud condensation by allowing humidity to accumulate around them — forming droplets and then clouds. To investigate the role of sulfur aerosols in cloud formation and climate change,...

Trees Release Volatile Organic Compounds That Aid In Smog Production
2013-04-26 09:53:33

Brett Smith for redOrbit.com - Your Universe Online In 2004, a group of Princeton scientists found trees release the volatile organic compound (VOC) isoprene that reacts in the air to form particulate pollution, or smog. However, the mechanism behind this process wasn't known until a new study from scientists at the University of North Carolina (UNC) was released this week showing how isoprene´s reaction to sunlight leads to the formation of harmful air pollution. After isoprene...

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...

Arctic haze is a phenomenon that occurs in the atmosphere at high latitudes in the Arctic due to air pollution. What distinguishes Arctic haze from haze found elsewhere, is the ability of its chemical ingredients to endure in the atmosphere for a longer period of time compared to other pollutants. Due to limited snowfall, rain, or turbulent air to displace pollutants from the polar air in the spring, Arctic haze can continue for more than a month in the northern atmosphere. Arctic haze was...

Haze is a type of atmospheric phenomenon where dust, smoke and dry particles in the air obscure the sky's clarity. Haze is created through various activities including farming, traffic pollution,and even wildfires. The World Meteorological Organization (WMO) categorizes the obscuration of the Earth's atmosphere by a list of different types of atmospheric phenomena. One of these is haze. The other classifications are: fog, ice fog, steam fog, mist, smoke, volcanic ash, dust, sand, and snow....
