Beetles Contribute To Air Pollution In Forests
2012-05-25 07:05:45

Brett Smith for RedOrbit.com Activity of the bark beetle is having an impact on both air quality and climate, according to a new report from a team of American scientists published in the journal Environmental Science & Technology. Evidence of the beetle´s impact can be seen in the lodgepole pine forests of the western United States. Many of the trees there are dying or ravaged by the beetles and a faint haze of particulate matter can be seen throughout the area. Air samples...

The hordes of bark beetles that have bored their way through more than 6 billion trees in the western U.S. and British Columbia since the 1990s do more than damage and kill stately pine, spruce and other trees. A new study finds that these pests can make trees release up to 20 times more of the organic substances that foster haze and air pollution in forested areas. It appears in ACS' journal Environmental Science & Technology. Kara Huff Hartz, Gannet Hallar and colleagues explain that...

The link between prenatal exposure to air pollution and childhood lung growth and respiratory ailments has been established by several studies in recent years, and now a new study suggests that these prenatal exposures can be especially serious for children with asthma. The study will be presented at the ATS 2012 International Conference in San Francisco. "In this study, we found that prenatal exposures to airborne particles and the pollutant nitrogen dioxide adversely affect pulmonary...

Certain areas of the United States were spared the effects of climate change thanks to the presence of tiny particles in the atmosphere, suggests new research from climate scientists at the Harvard School of Engineering and Applied Sciences (SEAS). Lead author Eric Leibensperger, a graduate student in applied physics at SEAS at the time of the study, and principal investigator Daniel Jacob, a professor of atmospheric chemistry and environmental engineering at SEAS and a professor of earth...

Older adults may be at increased risk of being hospitalized for lung and heart disease, stroke, and diabetes following long-term exposure to fine-particle air pollution, according to a new study by researchers at Harvard School of Public Health (HSPH). It is the first study to look at the link between long-term effects of exposure to fine particles in the air and rates of hospital admissions. The study will be published online April 17, 2012 in PLoS ONE. Prior studies have reported an...

Rice University study finds federal efforts most effective at cutting pollutants In a recent study published by the Journal of the Air & Waste Management Association, the Rice research group of environmental engineer Daniel Cohan looked at state implementation plans (SIPs) mandated by the United States Clean Air Act. SIPs detailed how states would attain standards set by the Environmental Protection Agency (EPA) for cutting ozone and other ground-level contaminants by 2009. The...

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....
