Show Atmospheric Pollution Study on Area Received Pollution in the atmosphere along the Green River was the subject of a highly technical tech-nical report received last week by William Taylor of the National Park Service. The report was based on a scientific expedition thru the Green River canyon which took place in June. The purpose of the expedition expedit-ion was to determine the amount of air pollution along al-ong a strip of the Green River Ri-ver that is known to be further fur-ther removed from automobile automo-bile activity thnn any other lonl'on in the United States. Mr. Taylor, chief natural- ist of Canyonlands National Park, received a copy of th? report on the findings of atmospheric at-mospheric contamination along al-ong the Green River. It was prepared by Thomas J. Henderson, Hen-derson, president of Atmospherics Atmo-spherics Incorporated of Fresno, Calif. The expedition into the isolated iso-lated section of the Green River was proposed a short time ago by Dr. Vincent J. Schaefer, director of the Atmospheric At-mospheric Sciences Research Center of the State University Univer-sity of New York. Dr. Schaefer Schae-fer made the discovery some three or four years ago that lead iodide ice nuclei can be formed from free iodine in the presnce of lead in automobile auto-mobile exhaust vapor. Ho proposed to take samples of the air in isolated sections of the United States and compare com-pare it with samples in more thickly populated areas. The expedition got underway under-way this past June with Dr. Frank C. Craighead in charge of the project. Dr. Craighead, president of Environmental En-vironmental Research Institute Insti-tute of Washington, D.C., received re-ceived national coverage a short time ago in connection with his experiments in tracking track-ing grizzly bears rigged with radio transmitters. the expedition participants put in at Ouray, Utah float-' ing in large rubber rafts by which they also carried their scientific measuring equipment. equip-ment. The team spent eglit days floating from Ouray to the mouth of Mineral Canyon Can-yon taking samples of the atmosphere along the way. Their findings, according to the report just received m Moab. indicated certain sections sec-tions along the Green River could be used as important bench marks for future atmospheric at-mospheric comparisons for purposes of ascertaining if the general continental air .mass" is being contaminated. Atmospherics Incorporated'? report also stated that it might be worthwhile to sample sam-ple the canyon top levels between be-tween Vernal and Mineral Canyon. An interesting result significant sig-nificant to the experiment was recorded in the reporr.
