The exhaust from diesel-fueled vehicles, wood fires and coal-driven power stations contains small particles of soot that flow out into the atmosphere. The soot is a scourge for the climate but also for human health.
The U.S. Environmental Protection Agency and the San Joaquin Valley Air Pollution Control District today announced a Clean Air Act settlement with Ralcorp’s Cottage Bakery in Lodi, Calif. after the facility failed to obtain permits and install proper air pollution controls.
A new study with NASA participation has sharply reduced previous estimates of how much carbon was emitted into Earth's atmosphere from tropical deforestation in the early 2000s.
The Polyisocyanurate Insulation Manufacturers Association (PIMA) has released a new study that analyzes and quantifies the energy and environmental contribution of polyisocyanurate insulation (polyiso) over the past 25 years.
Unhealthy air quality is predicted for the southern portions of Connecticut and Rhode Island, and the south coast of Massachusetts, including Cape Cod and the Islands, on Wednesday due to ground-level ozone.
Carbon stored in Arctic tundra could be released into the atmosphere by new trees growing in the warmer region, exacerbating climate change, scientists have revealed.
The U.S. Environmental Protection Agency (EPA) has proposed updates to its national air quality standards for harmful fine particle pollution, including soot (known as PM2.5).
American Seafoods Company LLC and Pacific Longline Company LLC have agreed to phase out the use of ozone depleting refrigerants, implement a comprehensive leak detection and repair program aboard a number of their vessels and pay a penalty to resolve federal Clean Air Act violations.
New research from Lawrence Berkeley National Laboratory (Berkeley Lab) has found that levels of methane—a potent greenhouse gas emitted from many man-made sources, such as coal mines, landfills and livestock ranches—are at least one-and-a-half times higher in California than previously estimated.
U.S. Environmental Protection Agency Regional Administrator Judith A. Enck met on Thursday, June 7, 2012 in New York City with representatives of local governments from Puerto Rico to discuss environmental challenges facing municipal governments in Puerto Rico, and explore solutions.
New groundbreaking research by scientists at Trinity College Dublin has found that exposure to nanoparticles can have a serious impact on health, linking it to rheumatoid arthritis and the development of other serious autoimmune diseases.
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.
