This dataset contains heavy metal measurement data for lakes across China. The sampling and analysis period ranges from 2014 to 2018, with its spatial coverage encompassing 14 provinces in eastern, northern, and western China. The data is stored in Excel spreadsheet files, which include three worksheets corresponding to the three regions respectively. Each worksheet holds the heavy metal measurement data of its corresponding region, and the columns in each worksheet are: lake name, lake code, sampling time, core sampling point number, sample number, layered depth, mercury (Hg), arsenic (As), cadmium (Cd), lead (Pb), copper (Cu), zinc (Zn), chromium (Cr), sampling organization, sampler, analysis organization, analyst, and person in charge. There are 9451 data records in total, with a total file size of 1.2 MB.
