...Another used bikini-clad girls to dispense 10,000 servings of ice cream to passersby. While the streets were enlivened by antiwar protesters, beggars and robed Buddhist monks, news cameramen recorded the scene from helicopters whirring about in the suddenly clear blue skies. At street level, concentrations of lethal carbon monoxide dropped from 10.5 parts per million...
...warm air kept heated air below from escaping. And what air! The city's brisk winds stopped dead; the sky darkened. Oxidants, caused by the reaction of nitrogen oxides and hydrocarbons to sunlight, became a major addition to the city's usual outpourings of sulfur dioxide, carbon monoxide and tiny particles of lead, asbestos and other suspended matter. Day after day the city's Department of Air Resources reported pollution levels ranging between "unhealthy" and "unsatisfactory." SO2 levels hit .23 parts per million parts of air at some points around the city, compared with the federal emissions...
...garbage that infest ghetto slums. Yet both DDT and rats directly degrade the quality of U.S. life. Nevertheless, some aspects of the environmental problem are clearly more pressing than others. For example, public-health and land-use planning should rank higher than campaigns against litter and noise. Curbing carbon monoxide in cities is more important than saving caribou in Alaska. For environmentalists, the new challenge is how to retain ecology's holistic view of man and nature while yet recognizing that the movement will soon fade unless it sets priorities that millions of Americans can understand and support...
...civil engineers at New York University, Alan H. Molof and Matthew M. Zuckerman, tested their method at a $69,962 pilot plant in New Rochelle, N.Y. They send sewage through an alkaline solution that breaks down large organic molecules. Then all the small molecules are adsorbed on activated carbon, a purifying material used in cigarette filters and gas masks. "Though the process needs to be perfected, it promises to be at least one-third cheaper than tertiary treatment," says Dr. Molof. "But its biggest advantage is that it produces absolutely clean water-not less-dirty water...
...molecules into various synthetic ring-shaped, larger molecules called "holders," which are in effect chemical vises. After many attempts, they hit upon a holder that gripped the ethyl alcohol and acetic acid so that they were properly oriented for combination; thus when the molecules met, their reacting oxygen and carbon atoms were always at the correct angle for electron snaring-and the reaction took place a million times faster. By "steering" the individual atoms, Koshland concluded, the holder molecule had apparently duplicated the exact role of an enzyme...
