Algae and Mosses Take Up Huge Amounts of Carbon Dioxide and Nitrogen

In cities, the presence of algae, lichens, and mosses is not considered desirable and they are often removed from roofs and walls. It is, however, totally unfair to consider these cryptogamic covers, as the flat growths are referred to in scientific terms, just a nuisance.

Children Exposed to Pollutant Found in Tobacco Show Signs of Chromosomal Damage

According to a new study, children exposed to high levels of the common air pollutant naphthalene are at increased risk for chromosomal aberrations (CAs), which have been previously associated with cancer. These include chromosomal translocations, a potentially more harmful and long-lasting subtype of CAs.

Light Pollution Transforming Insect Communities

Street lighting is transforming communities of insects and other invertebrates, according to research by the University of Exeter.

Bark Beetle May Impact Air Quality and Climate

At national parks out West, lodgepole pine trees are dying because of bark beetle. And atmospheric haze, caused in part by tiny solid particles suspended in the air, is becoming a problem.

Prenatal Pollution Exposure Dangerous for Kids With Asthma

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.

Pollution Warming Atmosphere Through Thunderstorm Clouds

Pollution is warming the atmosphere through summer thunderstorm clouds, according to a computational study published May 10 in Geophysical Research Letters.

Air Pollution Level Changes in Beijing Linked With Biomarkers of Cardiovascular Disease

During the 2008 Beijing Olympics, changes in air pollution were associated with changes in biomarkers of systemic inflammation and thrombosis (formation of blood clot) as well as measures of cardiovascular physiology in healthy young persons, according to a study in the May 16 issue of JAMA, a theme issue on Global Health.

El Paso Midstream Group to Resolve Clearn Air Act Violations in Utah

The U.S. Environmental Protection Agency has reached a settlement with El Paso Midstream Group, LLC resolving Clean Air Act violations at the Blue Bell Gas Plant near Roosevelt in Duchesne County, Utah.



QEP Field Services Will Pay $4 Million and Install Pollution Controls After Violating Clean Air Act

QEP Services, a Colorado-based natural gas services company, has reached an agreement with the Environmental Protection Agency and U.S. Department of Justice to resolve Clean Air Act violations at five natural gas compressor stations on the Uinitah and Ouray reservations in Northeastern Utah.

Humanmade Pollutants May Be Driving Earth's Tropical Belt Expansion

Black carbon aerosols and tropospheric ozone, both humanmade pollutants emitted predominantly in the Northern Hemisphere's low- to mid-latitudes, are most likely pushing the boundary of the tropics further poleward in that hemisphere, new research by a team of scientists shows.

Climate Policy Initiative Analysis: Four Major Countries Could Better Monitor Policies

Climate Policy Initiative (CPI)'s analysis of national systems that track emissions and activities to reduce emissions in the U.S., Germany, Italy and China revealed that existing systems allow these nations to determine if they are meeting their emission reduction targets, but do not allow them to identify which of their policies are most effective and efficient.

Carnegie Mellon University Student Builds C02 Fence

Sculpted by chemistry graduate student Longzhu Shen (MCS'12), the latest installation at CMU's ArtPark Lab uses environmentally friendly lighting to illustrate the fluctuation of carbon dioxide levels in Earth's atmosphere over the past 800,000 years.

How to Stop Summertime Sniffles and Other Allergic Reactions

Every spring and summer, millions of Americans dread the trip to the park or the playground and will do anything to avoid activities that trigger outdoor allergies.

EPA Updates Clean Air Act Requirements for Gas Stations to Reflect New Vehicle Technologies

The U.S. Environmental Protection Agency has determined that the systems used at gas station pumps to capture harmful gasoline vapors while refueling cars can be phased out. Modern vehicles are equipped to capture those emissions

PNNL Technology Wins Award for Improving Submarine Air Quality

Creators of a nanotech-based system that captures carbon dioxide directly from the atmosphere within a submarine, while providing a more environmentally friendly removal process, have won the Federal Laboratory Consortium Interagency Partnership Award for 2012.

Environment Key to Preventing Childhood Disabilities

The United States government would get a better bang for its health-care buck in managing the country's most prevalent childhood disabilities if it invested more in eliminating socio-environmental risk factors than in developing medicines.

Researchers Honored for Submarine Air Quality System

The United States Navy may deploy the nanotechnology-based system in its submarine fleet, according to the Pacific Northwest National Laboratory, which participated in the project.

EPA Takes Next Step to Implement 2008 Ozone Standards

Most areas that need to take steps to reduce ozone pollution are close to meeting the standards; only three new areas have been added.

EPA Works to Help the Nearly 26 Million Americans with Asthma

The U.S. Environmental Protection Agency (EPA) is encouraging Americans to take action against asthma by learning more about the disease and how it affects their families and communities. Nearly 26 million Americans, including more than 7 million children, are affected by this chronic respiratory disease, including low income and minority populations at the highest rates.

As Summer Smog Season Starts, Free Resources Help Protect People

Next week is Air Quality Awareness week – a cooperative effort amongst the U.S. Environmental Protection Agency (EPA), state environmental agencies, and the National Weather Service, to remind everyone to protect their health by paying attention to local air quality.
