210Pb-dated historical lake sediment metal concentrations from Norfolk, UK (mid-19th century to 2009)

Measurements of sediment properties (including organic and carbonate content), radionuclides (210Pb, 137Cs, 241Am) and elements (including mercury, nickel, copper, zinc, and lead) in lake sediment successions. Radionuclide dating provides a reliable chronology of sediment ages from the mid-19th century (sometimes only 20th century) to the present (2016). The dataset comprises a standardised matrix of multiple measured sediment variables (element values per mass) against stratigraphic depth for 8 lakes.

对湖泊沉积序列中沉积物性质（包括有机质和碳酸盐含量）、放射性同位素（210Pb、137Cs、241Am）以及元素（包括汞、镍、铜、锌和铅）的测量。放射性同位素年代测定技术为沉积物年龄的可靠年代序列提供了依据，时间跨度从19世纪中叶（有时仅为20世纪）直至2016年。该数据集包含了一个针对8个湖泊的标准化矩阵，其中包含了多个测量的沉积物变量（每质量单位的元素值）与地层深度的对应关系。
