This finding adds fertilizer to the growing list of substances though to be harmful to the ozone layer, including SST exhaust, freon and related compounds and the agricultural gumigant methylbromide...
McElroy said that "roughly half" of the freon now being released into the upper atmosphere comes from spray cans. Freon causes most of the reduction of the ozone layer, he said...
Last week the vulnerability of the ozone layer was emphasized by two startling reports on the long-range effects of the propellant gases used in aerosol sprays. Writing in Science, University of Michigan Physicist Ralph Cicerone notes that spray-can gases, mostly chlorine compounds such as Freon, are highly stable under ordinary circumstances. Thus they are building up in the lower atmosphere and gradually rising toward the ozone layer. At that altitude, ultraviolet radiation breaks down Freon and the other chlorine-based gases, causing the release of chlorine atoms. They in turn react with ozone, converting it into ordinary oxygen...

...team of Chicago doctors criticized the aerosol bronchial sprays that asthma sufferers, among others, increasingly use to help open constricted bronchial passages. After a detailed study, Drs. George Taylor and Willard Harris reported that some sprays produced abnormal heart rhythms in mice, rats and dogs. They also warned that Freon-the heavier-than-air gas used as a propellant in many of the bronchial nebulizers-is absorbed into the blood through the lungs and affects the heart. This may be responsible for the rising death rate among spray users during the past ten years. Published reports show more than...
