'Chemical Equator' discovery will aid pollution mapping
Scientists at the University of York have discovered a 'Chemical Equator' that divides the polluted air of the Northern Hemisphere from the largely uncontaminated atmosphere of the Southern Hemisphere.   view more (2008-09-24)

Key component of debilitating lung disease identified
For the first time, researchers have demonstrated a close correlation between the decline in a key component of the lung's antioxidant defense system and the progression of chronic obstructive pulmonary disease (COPD) in humans.   view more (2008-09-12)

Air Quality Forecasts for China
With less than a month remaining before the Beijing Olympics, Chinese officials have introduced a series of measures to improve air quality for the Games. A new tool has been installed in the capital city to allow the Chinese to monitor the effectiveness of these efforts.   view more (2008-07-24)

MIT researchers unravel bacteria communication pathways
MIT researchers have figured out how bacteria ensure that they respond correctly to hundreds of incoming signals from their environment.   view more (2008-06-13)

Road pollution blamed for higher allergy risk in kids
New evidence blames traffic-related pollution for increasing the risk of allergy and atopic diseases among children by more than fifty percent. What's more, the closer children live to roads, the higher their risk.   view more (2008-06-13)

Even low levels of air pollution may pose stroke risk
Short-term exposure to low levels of particulate air pollution may increase the risk of stroke or mini-stroke, according to findings that suggest current exposure standards could be insufficient to protect the public.   view more (2008-06-02)

Mother's prenatal stress predisposes their babies to asthma and allergy
Women who are stressed during pregnancy may pass some of that frazzlement to their fetuses in the form of increased sensitivity to allergen exposure and possibly future asthma risk.   view more (2008-05-19)

Biomonitoring
In a forthcoming special issue of the Inderscience publication, the International Journal of Environment and Pollution (2008, Volume 32, Issue 4), researchers from various fields explain how living organisms can be used to track the dispersal of atmospheric pollutants, particulates, and trace... view more (2008-04-25)

Scientists show that streams are critical to preservation of oceanic coastal zones
The plight of the world's oceans is dire, according to recent studies, through insults from human-derived activities depopulating and damaging reefs, altering coastlines, and creating pollutants, such as nitrogen runoff from terrestrial watersheds.   view more (2008-03-13)

Scientists find mercury threatens next generation of loons
A long-term study by the Wildlife Conservation Society, the BioDiversity Research Institute, and other organizations has found and confirmed that environmental mercury-much of which comes from human-generated emissions-is impacting both the health and reproductive success of common loons in the... view more (2008-03-05)

Toxins in cigarette smoke prevent stem cells from becoming cartilage
A toxic pollutant spread by oil spills, forest fires and car exhaust is also present in cigarette smoke, and may represent a second way in which smoking delays bone healing, according to research presented today at the annual meeting of the Orthopaedic Research Society in San Francisco.   view more (2008-03-04)

Investigating causes of asthma attacks: New sensor system monitors environmental exposure
Researchers at the Georgia Tech Research Institute (GTRI) have developed a sensor system that continuously monitors the air around persons prone to asthma attacks. Worn in the pockets of a vest, the new system could help researchers understand the causes of asthma attacks.   view more (2008-01-23)

First-ever study to link increased mortality specifically to carbon dioxide emissions
A Stanford scientist has spelled out for the first time the direct links between increased levels of carbon dioxide in the atmosphere and increases in human mortality, using a state-of-the-art computer model of the atmosphere that incorporates scores of physical and chemical environmental processes.   view more (2008-01-04)

Diesel exhaust fumes affect people with asthma, finds study on London's Oxford Street
Diesel exhaust fumes on polluted streets have a measurable effect on people with asthma, according to the first study looking at exhausts and asthma in a real-life setting, published on 6 December in the New England Journal of Medicine.   view more (2007-12-06)

Iowa State engineer develops laser technologies to analyze combustion, biofuels
Let's say a fuel derived from biomass produces too much soot when it's burned in a combustion chamber designed for fossil fuels. How can an engineer find the source of the problem? It originates, after all, in the flame zone of a highly turbulent combustion chamber. That's not exactly an easy place... view more (2007-12-06)

MIT: Prenatal arsenic exposure detected in newborns
MIT researchers have found that the children of mothers whose water supplies were contaminated with arsenic during their pregnancies harbored gene expression changes that may lead to cancer and other diseases later in life.   view more (2007-11-26)

Time spent in car drives up air pollution exposure
The daily commute may be taking more of a toll than people realize. A new study by researchers at the University of Southern California (USC) and the California Air Resources Board found that up to half of Los Angeles residents' total exposure to harmful air pollutants occurs while people are... view more (2007-10-31)

Toxic releases down from North American industry leaders, increasing from other facilities
The latest Taking Stock report from the Commission for Environmental Cooperation (CEC) reveals that a continued decline in releases of toxic chemicals to the environment-15 percent for the United States and Canada from 1998 to 2004-is being driven by a group of industrial facilities that are the... view more (2007-10-18)

Stronger EPA leadership needed to improve water quality in Mississippi River
The U.S. Environmental Protection Agency must take a more aggressive leadership role in implementing the Clean Water Act if water quality in the Mississippi River and the northern Gulf of Mexico is to improve, says a new report from the National Research Council.   view more (2007-10-17)

Scientists ramp up ability of poplar plants to disarm toxic pollutants
Scientists since the early '90s have seen the potential for cleaning up contaminated sites by growing plants able to take up nasty groundwater pollutants through their roots. Then the plants break certain kinds of pollutants into harmless byproducts that the plants either incorporate into their... view more (2007-10-16)

Ozone shuts down early immune response in lungs and body
As policy makers debate what levels of ozone in the air are safe for humans to breathe, studies in mice are revealing that the inhaled pollutant impairs the body's first line of defense, making it more susceptible to subsequent foreign invaders, such as bacteria.   view more (2007-10-01)
