Naphthenic acids and surrogate naphthenic acids in methanogenic microcosms

摘要

Naphthenic acids (Nas) are a complex mixture of naturally occurring acyclic and cyclic aliphatic carboxylic acids in petroleum In the Athabasca oil sands, Nas have been identified as the largest component of dissolved organic matter in the tailings waters from oils sands extraction processes. They are the major contributor to the acute toxicity of the fine tailings wastewaters at the oil sands extraction plants in northeastern Alberta, Canada.
