The behaviour of LAS in the environment

The behaviour of LAS in the environment During the last few years a considerable amount of information about the biodegradation of linear alkylbenzene sulfonates (LASs) in real environmental situations has been made available. This paper reviews the existing LAS concentrations found today in the environment, using specific analytical techniques for this surfactant, as well as its mineralization and fate in compartments such as sludge amended soils. LAS is totally decomposed into carbon dioxide, water and inorganic sulfate without formation of stable metabolites, and no accumulation has been detected in the compartments studied. The highest degree of biodegradation (>95%) takes place in the processes (sewers and sewage treatment plants) showing the shortest half lives (1–10 h). http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Journal of Chemical Technology & Biotechnology Wiley

Abstract

During the last few years a considerable amount of information about the biodegradation of linear alkylbenzene sulfonates (LASs) in real environmental situations has been made available. This paper reviews the existing LAS concentrations found today in the environment, using specific analytical techniques for this surfactant, as well as its mineralization and fate in compartments such as sludge amended soils. LAS is totally decomposed into carbon dioxide, water and inorganic sulfate without formation of stable metabolites, and no accumulation has been detected in the compartments studied. The highest degree of biodegradation (>95%) takes place in the processes (sewers and sewage treatment plants) showing the shortest half lives (1–10 h).
