Stoves Clean Most Polluted City in the World

Scientists at Lawrence Berkeley National Laboratory (Berkeley Lab) are known for designing high-efficiency cookstoves for Darfur and Ethiopia. Now they are applying their expertise to the windswept steppes of Mongolia, whose capital city, Ulaan Baatar, is among the most polluted cities in the world.

The scientists are working with the Millennium Challenge Corporation (MCC), a U.S. foreign aid agency, to improve air quality in the capital city by lowering emissions from outdated stoves and boilers. MCC has a five-year project in Mongolia to reduce poverty and promote sustainable economic growth. In 2010 the agency approached Berkeley Lab’s Ashok Gadgil, the driving force behind the Berkeley-Darfur stoves, to lend vision and technical expertise to solving Mongolia’s air quality problem.

Nanoparticle Coating Works with Sun to Clean Air

Researchers of the UPNA-Public Univ. of Navarre have developed a type of coating for construction materials. It is based on nanoparticles that interact with sunlight and trigger a chemical reaction that eliminates certain air pollutants. It is reckoned that the reduction in atmospheric pollution could be 90 percent of nitrogen oxides, 80 percent of hydrocarbons and 75 percent of carbon monoxides emitted. These coatings are the final result of the Ecofotomat project in which the L’Urederra R+D Centre and the construction company Obras y Servicios TEX S.L. have participated together with the university.

As the researcher Javier Goicoechea explains, the coatings, “Have special nanoparticles with a photocatalytic effect; the nanoparticles interact with the light, thus triggering a series of chemical reactions that clean the air and break down the dirt.”

Study Pinpoints Indoor Air Quality Risks

The rapid shift from nomadic life to modern-day culture in the United Arab Emirates has exposed residents to significant indoor air quality risks that can lead to respiratory illness, according to a new study from the Univ. of North Carolina at Chapel Hill.

With the swift modernization of the country, UAE governmental agencies have not performed the research required to pinpoint health risks, the study reported. The need to develop governmental research capacity makes collaborations with U.S. research teams vital, but the studies must be conducted in a culturally appropriate way.

Device Rids Buses of Dangerous Pathogens

The best place to enjoy a breath of fresh air may be a city bus, if Rice Univ. students have their way. A team of graduating seniors has created a system for public transit that would continually clear the air of pathogens that can lead to tuberculosis (TB), flu and pneumonia.

The CityBusters – Joseph Spinella, Jerry Lue, Sundeep Mandava, Grace Ching and Shidong Chen, all seniors – have installed a $500 device on a METRO bus in Houston that has proven effective at killing 99.8 percent of the pathogens that circulate through the air-filtering system. The device, called FluProof, incorporates high-powered ultraviolet lamps that sterilize the air on the fly.

Air Pollution Linked to Early Death in the U.K.In a study appearing this month in the journal Environmental Science and Technology, MIT researchers report that emissions from cars, trucks, planes and power plants cause 13,000 premature deaths in the United Kingdom each year.The researchers analyzed data from 2005, the most recent year for which information is available. They found that among the various sources of emissions in the country, car and truck exhaust was the single greatest contributor to premature death, affecting some 3,300 people per year. By comparison, the researchers note, fewer than 3,000 Britons died in road accidents in 2005.Read more: http://www.laboratoryequipment.com/news-Air-Pollution-Linked-to-Early-Death-in-the-UK-042312.aspx

North America’s Pollution Damages Europe’s CropsMan-made air pollution from North America causes Europe to lose 1.2 million tons of wheat a year, a new study has found. The research, led by the Univ. of Leeds and co-authored by the Univ. of York, shows for the first time the extent of the Northern Hemisphere’s intercontinental crop losses caused by ozone - a chemical partly produced by fossil fuels. The study also suggests that increasing levels of air pollution from one continent may partly offset efforts to cut carbon emissions in another.Read more: http://www.laboratoryequipment.com/news-US-Pollution-Damages-European-Crops-013112.aspx

Unit Improves Air, Energy Use in Animal Facilities

Researchers from North Carolina State Univ. and West Virginia Univ. have developed a new technology that can reduce air pollutant emissions from some chicken and swine barns, and also reduce their energy use by recovering and possibly generating heat. Specifically, the research team designed, built, and evaluated a proof-of-concept unit that incorporates a biofilter and a heat exchanger to reduce ammonia emissions from livestock barns, while also tempering—or heating up—the fresh air that is pumped into the barns.

The Search for Ultrafine Indoor Air Contaminants

Researchers at the National Institute of Standards and Technology (NIST) spent 75 days on the job carrying out some very important homework—measurements in a “typical dwelling” of the release, distribution and fate of particles almost as tiny as the diameter of a single DNA molecule. Particles ranging in size from 100 nanometers down to 2.5 nanometers that were emitted by gas and electric stoves, hair dryers, power tools and candles were tracked and analyzed.
