Acetone and 2‐butanone creation associated with biological and chemical remediation of environmental contamination

Abstract

Remediating environmental contamination by either biological or chemical methods typically results in the generation of temporary chemical intermediates as part of the process. These intermediate compounds may be related to either contaminant degradation pathways or reactions generated from the amendment itself. This article summarizes previously researched pathways and representative case studies discussing the authors' experience in generating relatively high concentrations of acetone and 2-butanone (also referred to as methyl ethyl ketone [MEK]) during both biological and chemical treatments. Experience shows that even relatively high concentrations of acetone and MEK intermediates are quickly attenuated and prove not to be a hazard outside of the treatment area. O

“…First, acetone was increasingly detected within the MPE stream, eventually reaching just over 3 percent of the total petroleum mass being extracted. Acetone is a common metabolic intermediate of anaerobic redox reactions, especially BTEX constituents (Fowler et al., ). We also noted the presence of the halomethane product chloroform and the dechlorinated byproduct methylene chloride.…”
