Sedimentation rate of the peat core was determined by 210Pb and 137Cs dating method. The sedimentation rate is 1.1 mm/yr, and the peat core with 40 cm length has a record of deposition for the past 350 years. The rate is consistent with reported values for the other peat cores in the island, and so is reliable. 14C ages of the peat samples were 1000-5000 years older than 210Pb and 137Cs ages, and this suggests that the 14C ages do not show actual depositional ages. Lead concentrations increased from 4 ppm in the lowest layer of the core to 60 ppm in the surface, and lead isotope ratios, 206Pb/207Pb and 208Pb/207Pb, decreased. This suggested that addition of anthropogenic lead increased to the present time. The lead in the lower layer is natural origin, and is a mixture of two components: lead derived from basaltic rocks in the Island and that in loess from the Eurasian continent. Since the late 19th century, anthropogenic lead has strongly affected to the peat. The lead isotopic trend suggests that contribution of the domestic anthropogenic lead emitted to the atmosphere has been small to the Rishiri Island, and that impact of anthropogenic lead mainly emitted from China and Russia to the Island has become strong.", "subitem_description_type": "Abstract"}]}, "item_9_description_5": {"attribute_name": "\u5185\u5bb9\u8a18\u8ff0",
