The EPA said it will approve revisions submitted by the Texas Commission on Environmental Quality to the state’s permitting program for major air pollution sources under the Clean Air Act’s New Source Review (NSR) program.
In the journal Nature, paleoclimate researchers reveal that about 12-5 million years ago climate was decoupled from atmospheric carbon dioxide concentrations. In the last five million years, changes in ocean circulation allowed Earth's climate to become more closely coupled to changes in carbon dioxide concentrations in the atmosphere.
The U.S. Environmental Protection Agency (EPA), the National Institute of Environmental Health Sciences (NIEHS) and the Department of Health and Human Services (HHS) Office of the Coordinator for Health Information Technology have announced a nationwide challenge called My Air, My Health (MAMH).
SABIC Innovative Plastics US LLC, and its subsidiary, SABIC Innovative Plastics Mt. Vernon, LLC, have agreed to pay about a $1 million civil penalty and improve leak detection and repair practices to settle alleged violations of the Clean Air Act (CAA) at chemical manufacturing facilities.
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.
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.
Street lighting is transforming communities of insects and other invertebrates, according to research by the University of Exeter.
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.
Pollution is warming the atmosphere through summer thunderstorm clouds, according to a computational study published May 10 in Geophysical Research Letters.
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.
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.
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.

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 (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.
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.
