While the existence of higher CO 2 levels overs cities—CO 2 domes—has been known for more than a decade, their effects on local air pollution has up to now not been explored. As such, reducing locally emitted CO 2 may reduce local air pollution mortality even if CO 2 in adjacent regions is not controlled. Mark Jacobson.

Sulfur dioxide is an air pollutant that causes acid rain, haze and many health-related problems. Two maps compare total annual sulfur dioxide amounts for India and China during 2005 (left) and 2016 based on Ozone Monitoring Instrument measurements.

Using biodiesel in construction vehicles offers promising environmental benefits in terms of reduced tailpipe emissions as well as reductions in fuel cycle emissions of selected pollutants, according to a new study by researchers at North Carolina State University. ozone, PM) problems may be less pressing.

Up there, 10 to 50 kilometers above the Earth’s surface, ozone molecules absorb the sun’s ultraviolet light, protecting life far below. Even less is understood about the potential risks to people and the environment—could the particles deplete the ozone layer, for example, or significantly alter the weather? about 0.6 °C.

We see it as similar to the ozone hole problem, where we really needed a tight, science-based focus on the limits to human inputs to the system--and howthose inputs affected the ozone layer's ability to keep people safe. by spewing pollution into the air.

Denver represents an interesting case study for exploring potential PHEV impacts because it violates the federal air quality standard for ozone and because several large EGUs [electricity generating units] are located in or near the urbanized area. Ozone concentration increases were modeled for small areas near central Denver.

Isoprene, a five-carbon diene formed naturally in plants and animals and a precursor of ozone, contributes more than 40% of these emissions. The scientists pointed out that converting the epoxides to aerosol is likely to be higher in polluted environments, because the aerosols’ acidity is generally higher when human activity is present.
