Electronic trash, known as e-waste, is piling up faster than ever in American homes and businesses. People do not know what to do with old televisions or computers so they throw them in the trash.
National Solid Wastes Management Association state programs director Chaz Miller says the large amount of electronic waste Americans generate is not unexpected. " We have so many electronic products that we use," said Miller. " They are being far more widely distributed throughout the population of the country and they tend to have relatively short life spans. Cell phones that last two or three years, computers that last maybe two or three years before they get replaced. "
The U. S. Environmental Protection Agency (EPA) estimates more than 400 million consumer electronic items are dumped each year, and there is a push by more states to ban the waste from garbage dumps and create recycling programs.
For example, as quickly as old electronics arrive at a recycling facility in Baltimore, they are torn apart and sorted for useable parts. Plant manager Mike Fannon says e-waste here is resold to other companies that further break down the components that are valuable. "There are a lot of valuable metals that can be recovered and reused as opposed to just putting them in the garbage dump, and in certain components there are some materials that should not really be dumped in the garbage dump," Fannon explained. Nearly 20 percent of electronic waste is recycled nationwide. Going back 13 years, it was only about six percent. Recycling rates continue to rise as more communities have banned electronics from garbage dumps in an effort to keep e-waste toxins (毒素,毒质) , like lead and mercury, out of garbage dumps. Many places have set up free drop-off sites where people can bring old items for recycling. Fannon says some items like old electronic circuit boards will get shipped to Canada, while other parts will be shipped to countries in Asia. "These will go off actually to a copper smelter where workers will recover copper within the circuit board as well as precious metals that are on the board," added Fannon. " There is gold plating on a lot of the material. There is silver. So all those precious metals are recovered in addition to the copper. "
This year several states like Vermont imposed a ban on electronic waste in garbage dumps. More can be done to boost electronic waste recycling.
Waste management analysts say U. S. facilities can safely recycle items. Environmentalists maintain they can reduce the amount of electronic waste in garbage dumps now by raising consumer awareness about the best ways to recycle e-waste. [br] According to Fannon, what precious metal can people get from used circuit boards?
选项
A、Iron.
B、Mercury.
C、Gold.
D、Lead.
答案
C
解析
根据题干中的get from used circuit boards定位到原文第四段最后三句。细节辨认题。本题考查在范农看来,人们能从旧的电路板上获得什么贵重金属。第四段援引范农的话,介绍了电子垃圾中的一些金属是如何被回收利用的,其中包括电路板上的铜以及部件上的镀金和银,故答案为C)“金”。
