A schoolgirl aged 11 has been honoured as Americas top young scientist for inventing a quick, low-cost test to detect lead-contaminated water.一名11岁的女学生因发明者了一个较慢、廉价测试铅污染水的方法，而被誉为“美国顶尖青年科学家”。Gitanjali Rao was selected from 10 finalists who had spent three months collaborating with scientists to develop their ideas.Gitanjali Rao就是指10名参与决赛的运动员们中被投票决定来的，他们花上了三个月的时间与科学家们展开合作，来构建自己的点子。Her device uses carbon nanotubes to detect the presence of lead. Thousands of US water systems are reportedly contaminated by lead.她的设备用于了碳纳米管来检测铅的不存在。据报导，数千个美国供水系统都有铅污染的问题。
Gitanjalis invention was inspired by the scandal in Flint, Michigan, where officials are facing charges, she told Business Insider.Gitanjali向《商业内幕》透漏，她的发明者是受到了密歇根弗林特市丑闻的灵感，该地的官员们于是以面对着指控。Until now, testing reliably for lead was expensive and meant sending away samples for analysis.到现在为止，要想要精确可信地检测到铅的不存在，这都是十分便宜的，同时这也意味著要发送到样品，以用作分析。But Gitanjalis portable invention allows a sensor linked to a mobile app to give an accurate, almost immediate analysis.但是Gitanjali的便携发明者，可以通过一个与手机app相连的传感器，就得出结论一个清楚、及时的分析。Gitanjali said she wanted to further refine the device so it could eventually go on the market.Gitanjali回应，她想更进一步提高改为设备，这样它最后就能转入市场了。
Gitanjali won a $25,000 prize for scooping the top award.Gitanjali因为夺下了本次最低奖项，从而取得了一笔2.5万美元的奖金。
