Ozone layer vanishing ... or is it?
Bv DAVID HAUBER
The ozone layer of the stratosphere went unnoticed for centuries, filtering out the sun's harmful ultraviolet rays. Recently, however, it has become a subject of great concern to environmentalists and business men alike.
Charges of destruction of this important oasis have been made by engraving.
They say the causes of the layer's depletion range from Concorge disease and bacterial infections to interoperal
William T. Coleman, secretary of transportation, rulened last month that the Concorde supersonic transport would be allowed to land at Dulles Airport outside Washington, D.C., and Kennedy International Airport in New York City.
Environmentalists are challenging Coleman's ruling in court, contending that the Concordia, besides being noise, is a violation of public health law, should be allowed to land in the United States.
COLLEMAN CALLED scientific evidence of the jet's effect on the atmosphere unconvincing, which relieved the jets from a threat to the national economy and the American market for the Concordore's.
The controversy over the Concordate may seem far removed from most people's daily lives. The fact that lives is whether the refrigerator works, their home or car is cool, or their underarms are dry. Each of these concerns, though, are closely related to the ozone
Rowland is now chairman of the department of chemistry at the University of California.
A former University of Kansas professor, F. Sherwood Rowland, presented a theory here last spring that the substances used in aerosol cosols and refrigeration units, Freen 11 and 12, were potentially harmful to stratospheric ozone levels.
The possibilities of banning such elements from commercial use would cause radical changes in the refrigeration and aerosol industries.
THE AEROSOL INDUSTRY, which uses Frecon as a propellant in spray cans, has already adapted to public concern by providing an emergency kit in commercial products. Rowland said.
William Lamb, technical supervisor for the Du Pont company's plant in Tucson,淋水队总经理。Freon, Du Pont had noticed a decline in its Freeport production since Rowland had made it available.
"There are a fair amount of scare tactics going on, but it hasn't stopped people from attacking the NHS."
The Tre DPont plant in Tecumshen doesn't produce Freon, he said, corporate policy has been set.
Increased advertising of roll-on deodorants, he said, was because of anticipated consumer reaction to the possible ill effects of Fren use.
"IF YOU'RE GOING to create a real scare on the subject," Lamb said, "your deodorant companies are going to get out of aerosols."
Rowland's theory of Freon's effect on the ozone layer is that inert Freon rises into the stratosphere and reacts with ultraviolet light to produce chlorine atoms that in turn react with the ozone to reduce it to simple oxogen.
Rowland said that a reduction in the ozone layer caused an increase in skin cancer. He
Professor says spring weather could continue
Although most Kansans know better than to expect 60-degree temperatures to last indefinitely, more spring weather may be in store.
Joe Eagleman, professor of geography and meteorology, said Monday that Kansas had been experiencing almost summer temperatures because the jet stream that usually crosses Kansas in winter had cool air almost to the Canadian border.
THE WEATHER typically will change from day to day and week to week, he said, but it will tend to be drier and warmer than usual.
Eagleman said a former graduate student of his who has left KU had done research to determine the relationship between university warm years and years of low humidity, acidity.
A sunspot is a storm on the sun that affe-
cues the nature of the sun's radiation heat.
The student predicted in 1972 that this year would be an unusually dry, warm one, be
ABOUT EVERY 22 years there is a period of a few years when sunspot activity is less than normal, he said, and the student had observed that those years corresponded to dry years.
Eagleman说 meteorologists didn't know exactly how the difference in radiation waves during years of low sunspot activity affected the temperature. It's just a small difference, but it can occur farther north and milder winters when sunspot activity is low, he said.
said that for every one per cent reduction of ozone, two per cent more ultraviolet light rays would leak through and cause a two per cent increase in skin cancer.

Lamb said. "There's been no evidence that there is a problem other than that of the drug."
ROWLAND'S THEORY is based on a mathematical model, Lamb said, that is simplicial compared with the complex meteorological factors of the stratosphere. The model suggests that it adequately consider naturally existing chlorine molecules in the stratosphere, which would indicate that it may not be a Freon problem, that it didn't include the effects of natural removal of Freon and that it could account for the increase in the computer theory weren't verified.
A group of manufacturing chemists recalled how lowland's estimate of ozone depletion was estimated.
"The they may be tagging the wrong animal," Lamb said of those citing Freon for ozone depletion. "The problem is real. If it's identified as Freon, we'll get out of the business. We don't want to harm the world."
Lamb said there were various studies of the ozone layer being done by universities, manufacturing research groups and government.

Clark Bricker, professor of chemistry, said,"The (manufacturing chemicals) data doesn't seem to indicate that it is clean and clear-cut on either side. As far as I'm concerned, there is no conclusive evidence in this area right now."
HOWEVER, HE ADDED, "I Professor Rowland is correct, it could be quite so."
'The whole problem is that until very
Another source of concern, Lambsaid, was in the refrigeration industry. The impact of any law banning the use of Freen as a condom would have substantial consequences, he said.
recently nobody has had any good analysis of the atmosphere."
He said that billions of dollars would be involved in any refrigeration system change-over. Fron is used in supermarket, railroad and home refrigerators and in oil dispensers.
**BRICKY SAID**, 'Any substitutes for the new now used undoubtedly be more expensive than the old.'
"We're going to pay the price one way or another. They (Freens) are comparatively cheap and they're safe from the point of view of handling."
Local air conditioning servicemen also expressed concern about any moves to the city.
"Freron has become the modern safe refrigerator, said Emory Scott of Scott's Tennis Academy."
Without Freon, he said, the whole refrigeration industry would have to resort to more dangerous alternatives such as ammonia or sulfur dioxide.
Any change would also require a change in the industry's equipment, he said.
Scott said that efforts to get rid of Freen were being promoted by "a lot of do-goodens who have to have a project to up their eos."
Bricker said, "I don't believe that of Sherry Rowland. I think he is a good scientist and he is interested in science," without refrigeration, Scott said. "Would he like old countries, like in Greece where they have to shop without refrigeration.
An air conditioning service manager who asked not to be identified, said, "It's going to affect a heck of a lot of people in the air conditioning industry. That would mean the industry would be hard pressed to find another method."
"PEOPLE WANT convenience now and they're going to buy them (refrigerators) as long as they can afford them. This is part of the American system. Who would trade it?"

"Virtually every state has one or more laws in the hopper on the subject," he said. It will take three years for any research on Freon to be conclusive, he added.
LEGISLATION IN KANSAS regarding Freon was introduced in HB 2015 by State Rep. Sandiford Duncan, R-Wichita, who is a board member for study until the next legislative session.
State Rep. Richard Walker, R-Newton, chairman of the public health and welfare committee, said, "We haven't spent very much time on it."
