Loss on ignition of sediments at different burning temperatures (ignition behavior) was conducted, and was compared with the total organic carbon, the organic carbon of unstable form organic matter (UFOM), and the organic carbon of humic substances, in order to classify the type of organic matter existing in littoral sediments of Hiroshima Bay. The results ensured that the origin of sediments could be classified based on the ignition behavior of the sediments. Importantly, the humic substance content determined from the ignition behavior denoted the same tendency of the measured value, ensuring that the ignition behavior can be used to classify UFOM and humic substances. It was also found that the ratio of loss on ignition at 300°C to that of 300-600°C could be used to classify the characteristics of sediment, as well as the C/N ratio.
