...unheralded killer. It does not occur in dramatic epidemics. Its victims in the U.S. are mostly blacks, and they generally receive less medical attention than whites. The malady affects the red blood cells, which normally are spherical. When the anemia victim is under any stress that reduces the oxygen supply in his blood, his red cells elongate into firm gel-like crescents ("sickles") that block narrow capillaries and deprive tissues of vital oxygen...
...have joined ecologists in stressing that phosphates can cause grave environmental damage. Pouring in a sudsy torrent from washing machines, detergents now account for about half of the growing amount of phosphates in U.S. waters. By overfertilizing algae and other plant life, phosphates start a process that depletes the oxygen supply in the water and eventually results in the eutrophication, or "death," of lakes and ponds. To counter that expanding threat to the nation's waters, four states and several counties and cities have either banned or begun phasing out the use of phosphate-bearing detergents. Manufacturers, under Government...
...water and white chalk bottom once moved poets to lyricism, is becoming clouded and dull. Industrial, agricultural and household chemicals-not to mention raw human wastes-drain uninterruptedly into the lake, where they fertilize enormous "blooms" of rust-colored algae. When these plants die, they sink and decompose, depleting oxygen supplies to such an extent that prized deep-swimming fish suffocate. "There are still transparent waters in mountain lakes, but these are too cold for anybody to jump in," mourns the Swiss magazine Eau-Air-Sante (Water-Air-Health). "We are liable to witness the departure of those tourists...
...first general agreement to pool space age hardware and know-how came in Moscow last October. Since then, the two nations have agreed to adopt lighting systems and color codes used by the Americans, and have chosen the nitrogen-oxygen cabin atmosphere preferred by the Soviet Union. In addition, both sides have decided upon new docking hardware different from the kind now used by either...
...inhabitants live in cities, and most of those cities and their industries are situated along the coast. Their effluents are fouling the water. Untreated sewage and industrial wastes discharged into portions of the Penobscot River in Maine have created sludge beds in the river and bay, and the oxygen levels of the water have been drastically reduced. This, in turn, is believed to be responsible for decreasing shellfish harvests in the Penobscot region...
