Abstract Cholesterol and 5β‐cholestan‐3β‐ol have been detected by thin‐layer and gas‐chromatographic means in hexane extracts of domestic sewage. Cholesterol was detected in the clear effluent after activated sludge treatment of domestic sewage, but 5β‐cholestan‐3β‐ol was undetectable in treated sewage. Attempts to detect either sterol in hexane extracts of marine bay water have not been successful because of the interference of other lipid‐like material.
