According to a new study led by a team at Duke University, airborne particulate matter and dust are cutting solar photovoltaic energy output by more than 25% in certain parts of the world, with roughly equal contributions from ambient PM and PM deposited on photovoltaic surfaces.

Based on their findings in a new study, researchers from the University of Washington and the University of Minnesota suggest that modifying urban form—as a means of affecting motor vehicle usage—may be a strategy to mitigate urban air pollution.

Although China and India remain the world’s largest consumers of coal, a new University of Maryland-led study found that China’s sulfur dioxide emissions fell by 75% since 2007, while India’s emissions increased by 50%. The results suggest that India is becoming, if it is not already, the world’s top sulfur dioxide emitter.

These were shown to be ozone-depleting, however, and were targeted for phasing out under the 1987 Montreal Protocol. However, HFC-134a, while having zero ozone-depletion potential, has a very high global warming potential—more than 1,500 times as much warming as an equivalent amount of CO 2.

The largest systematic study ever conducted of human volunteers exposed to ozone air pollution has found no evidence of effects on the heart in its healthy, older participants, but did find effects on the volunteers’ ability to breathe, even at low ambient levels.

Results from CHIE studies are used to inform the periodic review of National Ambient Air Quality Standards (NAAQS) for common pollutants, such as ozone and particulate matter (PM), and advise other policy decisions. The NAAQS process has broad health importance because it regulates the outdoor air concentrations of those pollutants.

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.
