New estimates obtained from ice core samples collected from the Siple Dome, West Antarctica, suggest that human activities have contributed approximately 25 percent of the modern carbonyl sulfide in the atmosphere. The results of the study, based on the first such measurements taken from ice, by Murat Aydin and colleagues at the University of California at Irvine, are published this month in the journal, Geophysical Research Letters, published by the American Geophysical Union.
WASHINGTON - The most abundant sulfur gas in the lowest layer of the Earth's atmosphere is carbonyl sulfide. While carbonyl sulfide is formed naturally, it is also produced through a chemical reaction in the atmosphere involving carbon disulfide, a chemical produced by a variety of industrial processes.
