CNN News: ?12歲女孩創(chuàng)意發(fā)明 檢測水中鉛含量

According to the World Health Organization, which is part of the United Nations, more than 2 billion people around the world don’t have clean drinking water in their homes. That’s about 28 percent of the entire world’s population.

世界衛(wèi)生組織隸屬于，據(jù)世界衛(wèi)生組織稱，全世界有超過20億人(約占全世界人口的28%)沒有干凈的飲用水。

And one threat that can hide in water is lead. It’s a toxic metal the U.S. government says no amount of it is safe, but there are some people working on ways to help others avoid it.

水中的一個潛在的威脅是鉛。這是一種有毒的金屬，美國政府說少量的鉛不會造成危險的，但是有一些人正在設(shè)法幫助其他人避免這種物質(zhì)。

GITANJALI RAO, INVENTOR: My name is Gitanjali Rao. I am 12 years old. I’m in seventh grade and I go to STEM School Highlands Ridge.

我的名字是Gitanjali Rao。今年12歲，上七年級，在STEM學(xué)校就讀。

So I developed a device to detect lead in water fashioned in current techniques out there today. It uses nanotube-based sensor in order to give you instantaneous results on your smart phone of safe, slightly contaminated or critical of the lead status in your water.

所以我發(fā)明了一種儀器，可以檢測出當(dāng)今技術(shù)中的鉛。它使用基于納米管的傳感器，以便在智能手機上立即獲得水是安全、輕微污染或鉛超標(biāo)的及時反饋。

I was originally introduced to the Flint water crisis through a STEM lab. And it was just appalling to see the number of people who were affected by lead in water.

我最初是通過一個STEM實驗室接觸到Flint水危機的，看到很多人受到水里鉛的影響，真是令人震驚。

I partnered with Denver Water and I am working on performing my tests and doing research there. So, at this point, I am working on redesigning the device structure, refining my sensors, adding various tables and charts for more accurate values.

我和Denver Water公司合作，我正在做我的測試并在那里做研究。因此，我正在重新設(shè)計設(shè)備結(jié)構(gòu)，改進傳感器，為更精確的值添加各種表格和圖表。

I want to see this in the market so that every -- it’s in everyone’s hands in the next year.

我想在市場上可以看到這個設(shè)備——這樣明年每個人就都可以擁有了。

According to the World Health Organization, which is part of the United Nations, more than 2 billion people around the world don’t have clean drinking water in their homes. That’s about 28 percent of the entire world’s population.
