Database of leaf and topsoil mercury in China’s urban forests

Based on an investigation of urban forests across local transects from urban central areas to rural areas in Beijing and a regional transect from north to south in eastern China, we estabished a database on leaf and topsoil (0-10cm) Hg concentrations. The data are used for the study entitled "Geographical patterns of leaf and topsoil mercury in China’s urban forests" (Earth's Future).
