More companies and recyclers are taking steps to ensure that old electronic devices such as TVs and computers aren’t sent to poor countries.

The Basel Action Network, a Seattle-based non-profit that largely exposed the overseas discarding (丢弃) of US electronic waste, on Thursday launched a programme to use third-party employees to certify (证实) recyclers who don’t export dangerous electronic waste.

The so-called e-Steward recyclers will also agree not to discard the waste in US landfills and agree to meet other criteria. The certification is intended to provide companies and consumers with some assurance that the waste, which can include toxins (毒素) such as lead and mercury, is disposed of safely.

The Government Accountability Office, in a 2008 report, declared that US electronic waste was often disposed of unsafely in such countries as India. There, workers recycle gold, silver and copper from the waste, often in open-air acid baths.

The Basel Network also says it won assurances from 13 organizations, including Samsung, Bank of America, Wells Far-go, that they’ll use e-Steward recyclers whenever possible. Wells Fargo had already been using recyclers who declared not to export. So far, Basel has certified three recyclers and seven sites.

Before e-stewards, even, companies that wanted to avoid export of electronic waste had to “hope for the best”, when, they handed their waste to recyclers, says Robert Houghton, president of Ohio-based recycler Redemtech. It is an e-Steward that counts major companies among its customers. “Now, they can get some proof,” Houghton says.

Basel’s standards compete with another set launched in January. It was made by industry and backed by the Environmental Protection Agency.

That standard, called R-2, doesn’t ban the export of dangerous electronic waste but requires that it be handled safely. Instead of a ban, the Institute of Scrap Recycling Industries says, efforts should be made to help poor countries develop safe recycling.

1.How were most electronic wastes dealt with before?

A. They were thrown into US landfills.

B. They were buried in the desert m die US.

C. They were exported to poor countries.

D. They were reused by families in poor countries.

2.E-Steward recyclers, main job is probably to ________.

A. prevent old devices from open-air acid baths

B. dispose of electronic waste safely

C. collect more electronic waste for profits

D. assure America’s leading rule in the electronic market

3.People in India import electronic waste to ________.

A. get rid of toxins　　 B. learn how to make devices

C. recycle valuable metals　　 D. make cheaper products

4.The passage is mainly about ________.

A. how to deal with old electronic products

B. the development of recycling in the world

C. how to fight against electronic pollution

D. safer treatment of electronic waste

For years, experts have been encouraging people to exercise, using steps as simple as taking the stairs instead of a lift and walking to work, where possible. A recent study bolsters this advice — it shows that frequent active exercise throughout the day can have great health benefits.

The study, published in the magazine Preventive Medicine, found that just 2 minutes of stair-climbing several times a day can lower total cholesterol(胆固醇), raise HDL (“good”) cholesterol and improve the heartbeat in young women who do not have much activity during the day.“such improvements may have important effects on the health of women, since, like cigarette smoking, poor fitness have been shown to be a high risk for heart disease and death in women,”said Dr.Colin Boreham with the University of Ulster in Belfast, Ireland and the fellow researchers of this study group. Furthermore, improvements in total cholesterol levels achieved in the study could cut the rate of heart disease in women by a third, they noted.

The team of researchers from Britain studied 12 women between 18-22 years old, before and after the exercise program. The women used a public staircase for about 2 minutes a day for 5 days a week. Compared with a group of 10 women who did not take part in the stair-climbing program, the women who climbed stairs showed marked improvements in health and fitness levels after 7 weeks. However, they did not show any signs of weight loss.“A short-term stair-climbing program can give great health benefits to young women. Stair-climbing may be a particularly suitable way of combining exercise with an individual’s daily lifestyle,”they pointed out.
