Limiting tracer method (LTM);
no correction for tracer
elements in foods or
medicines; soil intake was
estimated for three different
populations of children: one
expected to have high
intake, one expected to have
“typical” intake, and one
expected to have low or
background-level intake
To calculate mean and median values only those data that met the criteria specified by Van Holderbeke et al. ( 2008 ) were used, e.g. no values on Ti are
included and all data were corrected for background whenever background values are provided in the original paper
