In the manuscript, the data is with outlier. However, we used the data without outlier to construct the figure. The median (minimum and maximum) of SIR values were ‒124.3 (‒278.0 to 228.2), ‒210.2 (‒490.1 to 273.8), 27.1 (0.4 to 106.0), ‒22532.8 (‒29443.8 to ‒6215.9), 23.9 (‒45.3 to 268.0), 175.3 (‒56.4 to 1040.7), 39.2 (‒36.4 to 284.0), and ‒263.2 (‒491.4 to 132.3) mg/d for Al, Ba, Ce, Mn, Sc, Ti, Y, and V.” Point 5. At present, the related content in manuscript has been replaced to: “The SIR values based on the measured tracer element concentrations of food, feces, urine, soil and dust are presented in Table 1 and Figure 1.
Title- ‘in’ should be used for larger areas, can you add the study locations?
