Many studies have documented the decline in ozone pollution and its precursors in the Los Angeles air basin over the past several decades.
Carbon footprints are a familiar way to assess how green your lifestyle is, but now you can also measure your nitrogen footprint using a new tool, the N-Calculator.
Air pollution from wildland fires and urban and agricultural areas in California is diminishing air quality at Devils Postpile National Monument, according to a recent study published in the journal Atmospheric Environment.
A research team from Birkbeck, University of London, Royal Holloway University and Uppsala University in Sweden, have helped explain how ozone causes severe respiratory problems and thousands of cases of premature death each ...
(Phys.org) —A Purdue University-led team of researchers discovered sunlit snow to be the major source of atmospheric bromine in the Arctic, the key to unique chemical reactions that purge pollutants and destroy ozone.
(Phys.org) —Increases in ground-level ozone, especially in rural areas, may interfere not only with predator insects finding host plants, but also with pollinators finding flowers, according to researchers from Penn State ...
