Black carbon is part of a group of pollution sources known as Short-Lived Climate Forcers (SLCFs), including methane gas and ozone, which are produced on earth. Researchers tested air samples using a combination of real-time techniques, including aerosol mass spectrometry and photoacoustic spectroscopy. —Timothy Onasch.

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. Possible pathways by which ozone may cause adverse health effects.
