...pesticide is long-lasting and requires only one application per year. That makes it more popular with farmers than shorter-lived, less potent pesticides that must be used more often and only at specific stages of the corn plants' growth. Dieldrin's impressive durability, says the EPA, is the very quality that makes it an increasingly serious threat...
...concede that the changeover to unleaded gas may create some minor problems. The environmental agency will require an additional 10,000 stations in sparsely populated areas to offer unleaded fuel, and predicts that most smaller outlets for major oil companies will take on the new gas voluntarily. Altogether, the EPA estimates that in only 41 of the nation's 3,000-odd counties will motorists have to drive more than a few miles to find unleaded gas. Agency officials also note that 300,000 small nozzles have already been produced and are in wide distribution. In a pinch...
...recall is doubly irritating for Chrysler because the part causing the trouble was modified on the assembly line at the insistence of the EPA in the first place. The part, designed by Chrysler engineers, is a sensor containing a ball of wax that softens when engine temperature rises to 60° F. The softening frees a valve that recirculates part of the car's exhaust gases through the engine and thereby eliminates some of the harmful nitrogen oxides that are emitted at high temperatures; when the temperature subsides, the wax ball hardens and closes the valve. At first, Chrysler...
...balls were not softening properly on cars that had been driven for more than 10,000 miles or so. Instead of melting at 60°, the wax often was not responding until the engine temperature neared its typical maximum of around 200°. The company reported its findings to EPA officials, who promptly ordered the recall...
...year. Says National Audubon Society President Elvis J. Stahr: "The figures ... are unreliable, unscientific and quite possibly self-serving. Poisons simply are not the answer to the coyote problem. If they were, the problem should no longer exist." Despite its preference for aerial shooting and trapping, however, the EPA agreed last month to permit the use of the M44 on private land. Since roughly 12 million sheep graze at least part of the time on federal land, wool growers soon may seek permission to use coyote poisons there. Before approving, the Government will want an accurate estimate of how many...
