Scientists report that chemicals that are not controlled by a United Nations treaty designed to protect the Ozone Layer are contributing to ozone depletion.
Despite significant reduction in smog-producing toxins, the Greater Toronto Area still violates ozone standards
Despite a significant reduction in smog-producing toxins in past decade, GTA still violates Canada's ozone standards
A chemical used in dry cleaning and fire extinguishers may have been phased out in recent years but NASA said Wednesday that carbon tetrachloride (CCl4) is still being spewed into the atmosphere from an unknown source.
Sometimes even honey bees need help with "housekeeping," especially when it comes to cleaning their honeycombs once the honey's been removed. U.S. Department of Agriculture (USDA) research has shown that fumigating honeycombs ...
Scientists say warm upper air this September and October helped shrink the man-made ozone hole near the South Pole slightly.
Deciphering the molecular composition of organic aerosols, or OA, in the atmosphere is essential for understanding how these complex aerosols transform and impact the environment and climate forcing. The chemical composition ...
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.
(Phys.org) —A combination of extreme cold temperatures, man-made chemicals and a stagnant atmosphere were behind what became known as the Arctic ozone hole of 2011, a new NASA study finds.
People tend to think of ozone as something in the upper atmosphere that protects the earth's surface from UV radiation. At the ground level, however, ozone is a pollutant that damages crops, particularly soybean.
U.S. Department of Agriculture (USDA) scientists working with the University of Illinois at Urbana-Champaign found that future levels of ground-level ozone could reduce soybean yields by an average 23 percent.
