Abstract

In this study, the Tukey boxplot approach was adopted to develop geochemical baselines for 42 analyses in the East River basin, South China. Data subset analyses, change ratios and factor analyses were used to explore the anthropogenic effects and the influence of land use and geology on the spatial distribution of the geochemical baselines. The results revealed that whilst base cations were depleted, background levels of As, Pb, W and some rare earth elements were elevated relative to the crustal values. Subset analysis and factor analysis indicated that As, Pb and W were associated with anthropogenic activities, whereas rare earth elements were affiliated with the igneous geology in the study basin
