Correlations between the concentrations obtained using SRXRF (×10−6) (X) and ICP-MS or AAS (Y). The X-axis represents relative concentrations of metals by SRXRF (×10−6), while the Y-axis represents actual concentrations per gram of tooth enamel: a Y-axis is μg of Pb/g. b Y-axis is ng of Hg/g. c Y-axis is μg of Cu/g. d Y-axis is μg of Zn/g
