In methanogenic sediments from a petroleum-contaminated aquifer, [14C]benzene was converted to 14CH4 and 14CO2 without an apparent lag. Phenol, acetate, and propionate were intermediates in benzene mineralization. These results suggest that alternative electron acceptors need not be available for there to be significant natural attenuation of benzene in some petroleum-contaminated aquifers.
在一个受石油污染的含水层的产甲烷沉积物中,[14C]苯被转化为14CH4和14CO2,且没有明显的滞后现象。苯酚、乙酸盐和丙酸盐是苯矿化过程中的中间产物。这些结果表明,在一些受石油污染的含水层中,对于苯的显著自然衰减而言,不一定需要有替代电子受体。
