为了开展近岸海域污染历史的研究,需要建立可靠的测定现代海洋沉积物沉积速率的方法。早期的测年方法都不能获得百年内的沉积物可靠的沉积速率值。1972年Koide等开始用Pb~(210)测定现代海洋沉积物的沉积速率,取得了良好的结果。此后本法的研究报道很多,应用范围也日益广泛。我们在1981年建立了本法并应用于锦州湾污染历史的研 In order to carry out research on the pollution history of coastal waters, a reliable method for determining the sedimentation rate of modern marine sediments needs to be established. Early dating methods failed to achieve reliable sedimentation rate values ​​over the past 100 years. In 1972, Koide et al. Started to determine the deposition rate of modern marine sediments with Pb ~ (210) and achieved good results. Since then, many studies have been published in this law, and the scope of application is also increasingly widespread. We established this law in 1981 and applied it to the research on the pollution history of Jinzhou Bay
