We have reorganized the SM figures and the manuscript content. The modifications are as follows: “The frequency distribution histograms show few outliers, most being high values (Figure S3 (a) and Figure S4). Experimental factors such as measurement error, source error, and transit time misalignment, may lead to some of these outliers. Other outliers may be due to the behavior of certain children, such as pica behavior or spending unusually large amounts of time playing in grassland. The medians of the SIR values after removing the high values (see Figure S3(b) and Figure 1) were taken as the final SIR values for children living in the studied e‒waste dismantling site in South China.” Point 7.
