摘　　要：美国人蛋白质吃得太多,超过身体所需。摄入过量蛋白质对人体健康也许无害,却成为影响该国水道的问题。美国的废水中充斥着蛋白质消化后的残留物:含氮化合物——它们会为有害藻华提供营养,还会污染空气和饮用水。新的研究表明,这种氮污染堪比灌溉庄稼地时肥料流失造成的污染。In the U.S.,people eat more protein Lthan they need to.And though it might not be bad for human health,this excess does pose a problem for the country's waterways.The nation's wastewater is laden with the leftovers from protein digestion nitrogen compounds that can feed toxic algal blooms'and pollute the air and drinking water.This source of nitrogen pollution even rivals that from fertilizers washed off of fields growing food crops,new research suggests.
