Pollutant haze heats the Arctic
Arctic climate already is known to be particularly prone to global warming caused by industrial and automotive emissions of carbon dioxide and other greenhouse gases. Now, a University of Utah study finds a surprising new way society's pollutants warm the far north: the Arctic's well-known haze - made of particulate pollution from mid-latitude cities - mixes with thin clouds, making them better able to trap heat. (2006-05-10)

Tibet provides passage for chemicals to reach the stratosphere
In research that could improve climate prediction models, scientists at Georgia Tech and NASA have found that thunderstorms over Tibet provide a main pathway for water vapor and chemicals to travel into the stratosphere, home of the protective ozone layer. (2006-05-09)

In utero exposure to urban air pollutants can increase risk
Prenatal exposure to air pollutants in New York City can adversely affect child development, according to the results of a study released today by the Columbia Center for Children's Environmental Health (CCCEH) at the Mailman School of Public Health. Previous studies have shown that the same air pollutants can reduce fetal growth, but this study is the first to reveal that those pollutants can also affect cognitive development during childhood.

Researchers say environmental pollution is important piece of social justice debate
While environmental pollutants constantly swirl around children in all walks of life, past research has shown that children in poor, minority populations are disproportionately likely to be exposed to harmful toxins such as lead and agricultural pesticides. (2006-03-22)

Poor, ethnic children at greater risk for exposure to toxic pollutants
A study conducted at the University of Wisconsin found that African-American children living in poverty, and children of migrant farm workers have a higher risk of lead exposure compared to non-minority children living in non-agricultural settings. Although exposure to lead is associated with lower IQ levels in all children, this association is even more pronounced in African-American children. Such research has the potential to revise the socio-demographic variables associated with lead exposure. (2006-03-22)

'Reverse' tanning process could revolutionize leather industry
A new 'greener' and cleaner chemical process could revolutionize the leather-tanning industry, according to a report in the Feb. 15 issue of the American Chemical Society's journal Environmental Science and Technology. 'Reverse' leather tanning, which essentially works backward from the point where conventional tanning ends, saves time, money and energy while drastically slashing water use and pollution, researchers say. (2006-01-19)

Car make, age and fuel economy all affect how much vehicles pollute, study finds
When it comes to how much automobiles pollute, some makes are cleaner than others, according to new research. A study using data on nearly 4 million cars that underwent government-mandated emissions test in three states found that cars manufactured by German auto maker BMW were the least likely to fail these state pollution tests. Cars manufactured by Hyundai, Mitsubishi, Chrysler and GM were most likely to fail. (2006-01-09)

Risk/benefit analysis of farmed versus wild salmon
The benefits of eating wild Pacific salmon outweigh the risks because it has fewer cancer-causing contaminants than farmed salmon, but the risks of eating farmed Atlantic salmon outweigh the benefits for some people, say Barbara Knuth and Steven Schwager of Cornell University in a benefit-risk analysis in November's Journal of Nutrition.

Link between exposure to pollutants and type 2 diabetes
People exposed to high levels of persistent organochlorine pollutants (POPs), which are most likely to come from eating fatty fish such as salmon, might be at risk of developing diabetes. A study published today in the open access journal Environmental Health reveals that exposure to high levels of POPs, a family of toxic chemicals that includes polychlorinated biphenyls (PCBs) and the insecticide DDT, is associated with a high prevalence of type 2 diabetes mellitus.

Inexpensive oxidation catalyst could reduce diesel emissions
It's not a new material, but a new application of silver hollandite could make a big impact in diesel emissions control. Researchers at Pacific Northwest National Laboratory have developed an inexpensive method of synthesizing nano-sized silver hollandite and have found the material has unique catalytic properties that can completely oxidize nitrogens of oxide, carbon monoxide and hydrocarbons. These chemical reactions caused by the silver hollandite are key to reducing pollutants in diesel engine emissions. (2005-08-31)

Green catalyst destroys pesticides and munitions toxins, finds Carnegie Mellon University
A chemical catalyst developed at Carnegie Mellon University completely destroys dangerous nitrophenols in laboratory tests, report researchers at the 230th meeting of the American Chemical Society in Washington, D.C. Nitrophenols are man-made pollutants that mostly originate from wastewater discharges from the dye, pesticide and ammunition industries. Thousands of tons of these agents are produced yearly, and they are registered as priority pollutants by the EPA. Many of these compounds cannot be destroyed by existing means. (2005-08-28)

Grizzlies and salmon: Too much of a good thing?
Even grizzly bears should watch what they eat. It turns out that grizzlies that gorge themselves on salmon during the summer spawning season have much higher levels of contaminants in their bodies than their cousins who rely more on berries, plants and insects. The research by Canadian scientists is reported in the journal Environmental Science & Technology. (2005-08-08)

NCAR analysis shows widespread pollution from 2004 wildfires
Wildfires in Alaska and Canada in 2004 emitted as much carbon monoxide as did human-related activities in the continental United States during the same time period, according to new research by the National Center for Atmospheric Research (NCAR). The fires also increased ground-level ozone across much of the Northern Hemisphere. (2005-06-29)

Maryland's poor, African-American communities suffer disproportionate cancer risk from air pollution
New research from the Johns Hopkins Bloomberg School of Public Health found that Maryland communities that are poor and predominantly African-American incur a disproportionate cancer risk from ambient exposure to airborne toxins. Further, the researchers were able to identify the sources underlying the inequities. (2005-06-15)

Nature abounds with examples of bacteria that can thrive in extreme situations---surviving on toxic chemicals, for instance. In a paper published online in the Journal of the American Chemical Society (JACS) May 25, University of Michigan researchers show how some bugs manage to do that: by harnessing other potentially harmful chemicals known as free radicals to degrade the toxins they live on. (2005-06-02)
