2026-09-01 A Dataset of Zinc, Copper, and Lead Concentrations in Surface Water with Geographic Coordinates across China, November 2025 doi:10.57760/sciencedb.ecodb.0002d en The dataset comprises 881 records, each corresponding to one surface water monitoring site in China. In the data table, each row represents an individual monitoring site, identified by its geographic coordinates (longitude and latitude, in decimal degrees). The columns includethe average concentrations of three heavy metals—zinc (Zn), copper (Cu), and lead (Pb)—measured in November 2025. All heavy metal concentrations are expressed in milligrams per liter (mg/L). The data were sourced from the China National Environmental Monitoring Centre (CNEMC) for November 2025.
