Popular houseplants, known for reducing volatile organic compounds, also release them into the air, U.S. horticulturalists say. Members of the American Society for Horticultural Science say it is already known plants remove VOCs -- gases or vapors emitted by solids and liquids that may have adverse short- and long-term health effects on humans and animals -- from indoor air. However, the findings about houseplants also emitting VOCs need further study to determine any environmental health...

Chemicals pumped into the air by fossil fuels create smog-forming chlorine atoms that boost ozone levels, researchers in California said. Under extreme circumstances, the chemicals could account for nearly half of California's state-set limits on outdoor air pollution, scientists at the University of California, Irvine, said Monday in a release. We should be monitoring it and incorporating it into atmospheric models, chemistry professor Barbara Finlayson-Pitts said. We still don't really...
