| 内容記述 | Half a century after the serious mercury spill from a chemical factory, an updated situation report on the distribution of mercury deposits in the sediment and benthos of the intertidal zone of Minamata Bay was undertaken in 1997. On two stations inside and two more outside the Bay, mercury distributions in the surface sediment and benthos of the boulder intertidal shore were quantified and compared with those in control regions. The results indicated that relatively higher than the natural level of mercury deposits remained at one station inside the Bay, with lower levels at three other stations. The control regions, however, showed even lower levels than at those three stations. Nevertheless, the two stations outside the Bay were nearer to the control levels. Methylmercury distribution at the station with the highest value indicated a low correlation with that of total mercury. That is unlike the situation in a metallic mercury polluted area such as is involved in gold mining. The mercury distribution in the benthos indicated the same gradient of concentration as that of sediment throughout western Japan. | |||||
