Abstract

The indices to determine the weathering of crude oil, which were developed by Blumer, Ehrhardt and Jones (Deep-Sea Research, 20, 239–259, 1973), were applied with success to the tar that is being deposited on Bermuda. Relative to the fresh, floating incoming tar, sunken tar shows pronounced microbiological degradation while tar adhering to the rocky shore shows evaporative loss with less microbial degradation. Surprisingly, normal alkanes with an even number of carbon appear to be more prone to microbial degradation than the ones with an odd carbon number.

百慕大焦油的风化作用
Blumer、Ehrhardt和Jones(Deep Sea Research,20239-2591973)开发的确定原油风化的指数成功地应用于百慕大沉积的焦油。相对于新鲜的、漂浮的进入焦油,下沉的焦油表现出明显的微生物降解,而附着在岩石海岸的焦油则表现出蒸发损失,微生物降解较少。令人惊讶的是,碳数为偶数的正烷烃似乎比碳数为奇数的烷烃更容易被微生物降解。
