Understanding of variances in properties of lipids plays an important role in considering the restoration of littoral environment. Here, loss on ignition (LOI) of sediment is investigated in combination with element analysis, n-hexane extract, and fatty acid analysis in order to provide a better understanding of variances in the lipid properties of sediment. It was found that the sediment that had large amounts of unstable organic matter (UOM) contained large amounts of lipids, and the lipid amount linearly decreased along with the decreasing amount of UOM. This ensures that the decomposition of UOM can be understood based on variances in the lipid properties. Furthermore, it is evident from our results that the decreasing amount of organic matter in transport processes differed from that in decomposition processes of accumulated sediment.
