Almost 80 percent of air pollution involving soot that spreads from China over large areas of East Asia — impacting human health and fostering global warming — comes from city traffic and other forms of fossil-fuel combustion, such as home cooking with coal briquettes.
A team of Wayne State University researchers are working on a technology that could quickly and significantly reduce the emission of mercury and other toxic substances by power plants into the Great Lakes basin.
NASA has changed the day for a behind-the-scenes look at the agency's airborne campaign to study how storm systems combine with air pollution from wildfires and other sources to affect our climate. NASA now will host its pollution-climate science flights media day from 1-3 p.m. CDT on Thursday, Aug. 22, in Houston.
A multi-year NASA science mission soon will be airborne over Houston to help scientists measure and forecast air quality from space.
Three elements commonly found at elevated levels in an Appalachian river polluted by runoff from mountaintop coal mining have distinctive chemistries that can be traced back to their source, according to a Duke University-led study.
As demand climbs for more fuel-efficient vehicles, knowledge compiled over several years about diesel engines and a new strategy known as “low-temperature combustion” (LTC) might soon lead auto manufacturers and consumers to broader use of cleaner diesel engines in the United States.
More forms of mercury can be converted to deadly methylmercury than previously thought, according to a study published Sunday in Nature Geoscience. The discovery provides scientists with another piece of the mercury puzzle, bringing them one step closer to understanding the challenges associated with mercury cleanup.
For a behind-the-scenes look at NASA's upcoming airborne campaign to study how air pollution from wildfires and other sources affects our climate, NASA will host a media day from 8-11 a.m. CDT Wednesday, Aug. 21, in Houston.
Scientist Brett Singer is a vegetarian. So why has he been frying up hamburgers? Singer and his team of Lawrence Berkeley National Laboratory (Berkeley Lab) indoor air researchers have found hazardous levels of nitrogen dioxide and carbon monoxide in a surprisingly large portion of California home kitchens. What’s more, their studies have shown that the most common device for mitigating this indoor air problem—range hoods—vary widely in performance.
A family of molecules developed at Carnegie Mellon University to break down pollutants in water is one step closer to commercial use. Study results published online in the journal Green Chemistry show that the molecules, which are aimed at removing hazardous endocrine disruptors from water sources, aren't endocrine disruptors themselves as they proved to be non-toxic to developing zebrafish embryos.
