...This does not mean, however, that all cause for concern ceases. A common characteristic of the two plants, for example, is that they are both boiling water reactors. This type of reactor (pressurized water reactors are the alternative kind of reactors in current use) has a record of annually emitting hundreds of thousands of curies of radiation into the environment. Pressurized water reactors, on the other hand, emit hardly any radiation. Why was the more polluting kind of reactor chosen? What kind of hazard is posed by the emissions of the boiling water reactor? These are the kind of questions...
Texas Works has only two smokestacks, and these emit almost no smoke. The two giant 200-ton furnaces are fueled by a careful mixture of natural gas and air that is almost smokeless, and 25,000-h.p. fans blow the few exhaust fumes through a cooling water spray that removes all solid particles. The ultimate discharge from the stacks is made up of relatively equal parts of warm oxygen and carbon dioxide...
...AUTOS emit the bulk of carbon monoxide and hydrocarbons. Under the new rules, clean air means a maximum nine parts of CO per million parts of air during an eight-hour period. Hydrocarbons are limited to .24 p.p.m. for a maximum of three hours...
...INDUSTRY emits most sulfur oxides and particulates (soot, fly ash, heavy metals). Clean air now means a maximum 80 micrograms of sulfur oxides per cubic meter of air and 75 micrograms p.c.m. of particulates as an annual mean. Both sources emit about the same amounts of nitrogen oxides, which the rules now limit to .05 p.p.m. of air. Both also contribute to photochemical oxidants, which are formed by the action of sunlight on hydrocarbons and nitrogen oxidants. The new rules limit photochemical oxidants to .08 p.p.m. of air. All this could sharply reduce present levels of air pollution. CO levels...
...aerospace industry and some 30 labor unions. It has placed full-page ads in leading newspapers. One pictures a boy holding a model of the SST and asks: "Will SSTs really pollute his world?" The answer, claims the ad, is that one SST moving at 1,780 m.p.h. "will emit no more pollutants per mile than three compact automobiles traveling at 60 m.p.h." As for sonic boom, the craft will be banned over land. At sea, the ad contends, the boom effect on the ocean surface will be "comparable to the impact of a fisherman's spinning lure hitting...
