| Abstract: | Linear alkyl benzenes (LABs), which have been proposed as markers of the hydrocarbon component of domestic wastes, were measured in sediments from three areas of Port Phillip Bay (Australia). The concentrations found (0–19 μg g−1) were generally lower than those reported for other coastal sediments from the USA and Japan. This is thought to reflect the small quantity of domestic wastes entering Port Phillip Bay.Compositional profiles showed that both physical and biological processes had acted to remove LABs during deposition.At one site, unusual alkyl benzene compounds, but no conventional LABs, were detected. These compounds were probably synthesised terrestrially by the bacteria of a nearby sewage farm. |
