2006年VOA标准英语-Beach Bacteria Leaves Swimmers Stranded at Shor(在线收听) |
By Melinda Smith ------- The warning comes as millions of families worldwide are spending their summer vacations at the shore. In 2005, there were more than 20,000 U.S. cases of water contamination. Everything from household trash -- like toilet paper -- to sewage spills and runoff. Environmental specialist Brad Delashumutt monitors the water at Virginia Beach, Virginia. He says high bacteria levels can even be caused by bird droppings. "You can get a large flock of seagulls concentrated in an area of the beach that can raise the levels." Beach bacteria is believed to be a worldwide problem, particularly in countries with little or no standards about sewage runoff. But it is difficult to find records of beach closings because of water bacteria. No matter which country they live in, children and the elderly are especially susceptible to waterborne bacteria. It can cause serious intestinal problems. Gastro-enteritis, diarrhea, hepatitis and kidney infections are common results. As one environmentalist put it, 'A day at the beach should not mean a night spent in the bathroom. Or even worse, in the emergency room.' |
