Indoor Pollution
Since the early eighties we have been only too aware of the devastating effects of large-scale environmental pollution. Such pollution is generally the result of poor government planning in many developing nations or the short-sighted, selfish policies of the already industrialized countries which encourage a minority of the worlds population to waste the majority of its natural resources.
While events such as the deforestation of the Amazon jungle or the nuclear disaster in Chernobyl continue to receive high media exposure, as do acts of environmental sabotage (阴谋破坏) , it must be remembered that not all pollution is on this grand scale. A large proportion of the worlds pollution has its source much closer to home. The recent spillage (溢出量) of crude oil from an oil tanker acci- dentally discharging its cargo straight into Sydney Harbor not only caused serious damage to the harbor foreshores but also created severely poisonous fumes which hung over the suburbs for days and left the angry residents wondering how such a disaster could have been allowed to happen.
Avoiding pollution can be a full-time job. Try not to breathe in traffic fumes ; keep away from chemical plants and building-sites; wear a mask when cycling. It is enough to make yon want to stay at home. But that, according to a growing body of scientific evidence, would also be a bad idea. Research shows that levels of pollutants such as hazardous gases, particulate matter and other chemical "nasties" are usually higher indoors than out, even in the most polluted cities. Since the average American spends 18 hours indoors for every hour outside, it looks as though many environmentalists may be attacking the wrong target.
The latest study, conducted by two environmental engineers, Richard Corsi and Cynthia Howard Reed, of the University of Texas in Austin, and published in Environmental Science and Technology, suggests that it is the process of keeping clean that may be making indoor pollution worse.
