[Abstract] The historical trend of the lead pollution in the Kinki district was elucidated by analysis of aquatic sediment core. The chemical species of the lead in sediment was estimated by chemical leaching technique because the changes of the aquatic environment can be assumed by the chemical species of heavy metal in the sediment. In this study, the chemical species of lead in sediment core was determined by a continuous extraction method with four fractions using by some solvents. The fractions of carbonate, hydroxide, sulfide (organic), and silicate of lead were dissolved with 10％-HOAc, 10％-HOAc＋0.2M-NH_2OH • HCl, 0.015M-HNO_3＋H_20_2, and Conc.-HNO_3＋HF, respectively. The lead species in the sediment core of Osaka Bay and moat of Osaka Castle has revealed by the chemical leaching technique. The concentration of lead increases after the Meiji restoration in each core, the peak is shown in 1960's, and it has decreased until the present age. It agreed well with the trends of the human and the industrial activities of Japan. The carbonate and hydroxide of lead in the sediments were predominant species, however sulfide was relatively little. It is indicated that anthropogenic polluted lead were precipitated as carbonate and hydroxide into sediment. It is thermodynamically anticipated that the lead exists as a carbonate in the environmental conditions of the sediment. The results of analyses agreed well with theoretical presumption. |
