...bigger steps toward a cleanup: a $5 billion, five-year effort, with costs split by the Government and business, to develop technology for burning coal more cleanly. The huge quantity of coal burned by the industrial and electrical plants of the Ohio Valley is a major source of airborne sulfur oxides that return to earth as acid compounds...
...notes, "appears to be treeless when, in many places, it is actually covered with trees--a thick matting of short, ancient willows and birches. You realize suddenly that you are wandering around on top of a forest." Icebergs the size of Cleveland drift through the dark waters, and sulfur butterflies mysteriously rise in the short, delirious summer. Mirages provide a weird history and geography: "A Swedish explorer had all but completed a written description in his notebook of a craggy headland with two unusually symmetrical valley glaciers, the whole of it a part of a large island, when he discovered...
Pioneer will continue to observe Halley's, measuring water loss and looking for oxygen, carbon, sulfur and other elements in the coma's gases, until March 6, when the sun will begin blocking the Venusian view of the comet. On that day, however, the first of an international flotilla of spacecraft will take over Halley's vigil. The Soviet probe Vega 1 will fly through the coma, passing within 6,000 miles of the nucleus. It will be followed by another Soviet craft, two Japanese probes, and the European Space Agency's Giotto, which will make the most daring pass...
...coma and brain damage, as well as death. Asthmatics appear to be at greatest risk. The FDA estimates that 450,000 asthma sufferers, or 5%, are sulfite sensitive. For many, suggests Immunologist Ronald Simon of the Scripps Clinic and Research Foundation in La Jolla, Calif., the problem stems from sulfur dioxide, which is released by the sulfite solution. The fumes cause spasms in the bronchial tubes, preventing oxygen from getting into the lungs and blood. Notes Dr. Simon: "Asthmatics are exquisitely sensitive to sulfur dioxide...
Soviet doctors stress the restorative virtues of spa vacations. At many resorts, visitors can immerse themselves in bubbling sulfur baths or inhale herbal steam. At Sochi, where the beach is covered with black pebbles instead of sand, white-uniformed nurses patrol seaside stretches with names like Medical Beach and Health Beach, enforcing a 55-minute limit on exposure to the sun's rays, even for the swarthiest guest. The preferred way for getting a quick tan is to stand facing the sun with arms held aloft. Because of a shortage of swimsuits and suntan oil, beaches are crowded with thousands...
