Includes bibliographical references. "This paper examines the stability of sediment-bound coprostanol in laboratory bench-top tests over 50 days of exposure to a vigorous bacterial flora. The experiments were carried out in triplicate at room-temperature and under aerobic conditions. For comparative purposes, the microbial degradation of other organic additives was monitored. They were: n-C20 alkene, n-C21 alkane, Benzo (a) anthracene, erucic acid, tricosanoic acid, n-C26 alcohol, and another steroid stigmasterol. Extraction solvent was methanol / dichloromethane and analysis was by GC-MS with FID detector. The results show that coprostanol was resistant to degradation over the 50-day period"--Abstract. gccst Waste water Bourbonniere, Richard A., author. Coakley, J. P. author.
