章節(jié)摘錄

　　Most people are aware that outdoor air pollution can damage their health， but many donot know that indoor air pollution can also have significant health effects. Environmental Pro-tection Agency studies indicate that indoor levels of pollutants may be 2~5 times， and occa-sionally more than 100 times， higher than outdoor levels. These levels of indoor air pollutantsmaybe of particular concern because most people spend about 90 % of their time indoors.　　____These include buming sources such as oil， gas， coal， wood， and tobaccoproducts； building materials and furnishings； products for household cleaning， personalcare， or hobbies； central heating and cooling systems； and outdoor sources， and outdoorair pollution. Immediate effects may show up after a single exposure or repeated exposures.These include a sense of being annoyed， as in relation to the eyes， nose， and throat，headaches， tiredness and so on. ____Sometimes the treatment is simply doing away withthe person's exposure to the source of the pollution， if it can be identified. Symptoms（癥狀）of some diseases， including asthma， hypersensitivity， pneumonitis， and fever， mayalso show up soon after exposure to some indoor air pollutants. Certain immediate effectsare similar to those from colds or other viral（病毒的） diseases， so it is often difficult todetermine if the symptoms are a result of exposure to indoor air pollution.____If thesymptoms disappear when a person is away from the home and retum when the person re-turns， an effort should be made to identify indoor air sources that may be possible causes.Some effects may be made worse by a not-enough supply of outdoor air or from the heat-ing， cooling， or humidity conditions prevalent in the home. Other health effects may showup either years after exposure has occurred or only after long or repeated periods of expo-sure. These effects， which include some respiratory diseases， heart disease， and cancer，can be severely debilitating or fatal. It is prudent to try to improve the indoor air quality inyour home even if symptoms are not noticeable.　　While pollutants commonly found in indoor air are responsible for many harmful ef-fects， there is considerable uncertainty about what concentrations or periods of exposureare necessary to produce specific health problems____Therefore， further research isneeded to better understand the effects of indoor air pollution and to find efficient ways toprotect our health. 　　……?
