报道了在模拟池塘的小生境中~(147)Pm在水体、土壤及水生生物之间的转移和积累情况,并对其进行了动力学模型分析。结果表明,~(147)Pm在小生境中的转移与积累均符合一级反应动力学模式;水生植物对~(147)Pm的浓集能力最强,可作为环境监测的指示生物和用于净化水体;鲤鱼对~(147)Pm的吸收极少,且大部分积累于骨骼中;~(147)Pm在土壤中的渗透力较弱,80％积聚于表层1cm内。 The migration and accumulation of ~ (147) Pm in water, soil and aquatic organisms in a simulated pond were reported and their kinetic models were analyzed. The results showed that the migration and accumulation of ~ (147) Pm in the niche were consistent with the first order kinetic model. The aquatic plant had the strongest ability to collect ~ (147) Pm and could be used as indicator organ for environmental monitoring Purified water body; carp had little absorption of ~ (147) Pm, and most of it accumulated in the bones; ~ (147) Pm penetrated weakly in the soil and 80% accumulated in the surface within 1cm.
