When two lignites and a sub-bituminous coal were subjected to hydrothermal treatment (HTT), the leaching of organic matters from coal was evaluated by total organic carbon (TOC). The degree of TOC in the HTT eluent was greatly increased as the HTT temperature was raised. The HTT eluents from these low-rank coals were assessed in terms of Ames Salmonella mutagenicity assay and acute toxicity test for D. magna and O. latipes. The eluents from the HTT eluent did not show any notable mutagenicity. However, an appreciable degree of mutagenicity after chlorination was observed for the HTT eluents. The eluents from HTT indicated a considerable acute toxicity for D. magna and O. latipes.
