A new study conducted by Chinese scientists has shown that some chemical extracts from cigarette butts can be used to protect steel pipes from rusting.

After immersing cigarette butts in water, researchers found nine chemicals, including nicotine and applied the extracts to N80, steel used in oil pipes, Reuters reported.

According to the study published in the American Chemical Society's bi-weekly journal Industrial & Engineering Chemistry Research, the extracts protected the pipes from rusting.

"The metal surface can be protected and the iron atom's further dissolution can be prevented," the authors wrote.

Oil pipe corrosion costs millions of dollars every year and 4.5 trillion cigarette butts, containing enough toxins to kill fish, find their way into the environment each year.

"Recycling could solve those problems, but finding practical uses for cigarette butts has been difficult," the paper said.

With 300 million smokers, China is the world's largest smoking nation and consumes one-third of the world's cigarettes.

更新時間 2010年 5月 13日, 格林尼治標準時間12:06
中國科學家表示，他們發現從香煙過濾嘴裏提取的化學物質可用來防止鋼管生鏽。

這份發表在美國化學協會雜誌上的報告稱，過濾嘴浸泡在水中可產生9種不同化學物質，如果應用於的鋼材，可防止鋼管生鏽。
