There is no question that the old style
of air pollution could kill people. In one week following the infamous
"peasouper" fog in December 1952, 4, 700 people died in London. Most of these
people were elderly and already had heart or lung diseases. A series of these
killer fogs eventually led to the British Parliament passing the Clean Air Act
which restricted the burning of coal. Fortunately the effect of smog on the lungs is not so dramatic. Scientists have now conducted a number of laboratory experiments in which volunteers are exposed to ozone inside a steel chamber for a few hours. Even at quite low concentrations there is a reversible fall in lung function, an increase in the irritability of the lungs and evidence of airway inflammation (发炎). Although irritable and inflamed lungs are particularly seen in people with asthma (哮喘) and other lung disea A. Low concentrations B. Fall in lung function C. Irritability of the lungs D. Air way inflammation [简答题] Air Pollution
When people think about air pollution, they usually think about smog, acid rain, CFC’’s, and other forms of outdoor air pollution. But did you know that air pollution also can exist inside homes and other buildings It can, and every year, the health of many people is affected by chemical substances present in the air within buildings.
A great deal of research on pollution is being conducted at laboratories and universities. The goals of the research are to find solutions and to educate the public about the problem. Two places where this type of work is being done are LBNL and the University of California, Berkeley. Let’’s take a closer look at the various types of air pollution, the effects that they have on people, and what is being (or not being) done to correct the problem.
