美国埃克森石油公司的专家发现,含氮丰富的化肥可成为清除石油污染极好清洁剂。 1989年,该公司一艘油轮把1000万加仑原油泄漏在阿拉斯加附近海域。专家在1989～1992年的3年中,先后把大约11万磅氮肥和1万吨磷肥撒在被石油泄漏严重污染的海滩上以分解原油,收效良好,海滩石油污染基本得到清除。 Experts from Exxon Petroleum in the United States have found that nitrogen-rich fertilizers can be an excellent detergent for removing oil pollution. In 1989, an oil tanker of the company leaked 10 million gallons of crude oil in the waters near Alaska. During the three years from 1989 to 1992, the experts had scattered about 110,000 pounds of nitrogenous fertilizer and 10,000 tons of phosphate fertilizer on the beaches that were heavily polluted by oil spills to decompose the crude oil. The results were good and the oil pollution on the beach was basically eliminated.
