Normalized patterns for the potential toxic element contents in the soils. (a), upper continental crust (UCC) normalized data are from19; (b), background values of China soils (BVCS) normalized data are from20; QS and QD, the surface and deep soils developed in quaternary sediments; GS and GD, the surface and deep soils developed in granite plutons.
