Historical trends of hexachlorobenzene (HCB) in sediment cores were simulated using the emission estimate and the dynamic multimedia environmental fate model. Emission sources considered were as follows: impurities in pesticides (pentachlorophenol (PCP), pentachloronitrobenzene (PCNB), dimethyl-tetrachloroterephthalate (TCTP) ), incineration of HCB containing waste from tetrachloroethylene production, and incineration of municipal solid waste. The simulation results were compared with the measured trends of HCB in sediment cores taken from Lake Biwa and Osaka Bay. Delayed arrival of HCB in the sediment partly explained the difference between the emission trend of HCB and the measured sediment core trend. The difference in the time trend between Lake Biwa and Osaka Bay seems to reflect their different sources and pathways of HCB emission.
