Selection criteria: elements that are included in the LAWA list of threshold values (LAWA GfS, “Geringfügigkeitsschwellenwert”, English “insignificance threshold”) from 2016 [42]; concentrations in the range of the LOQs (limits of quantification) are not included
^aData from sealants and coatings are mean values of two leaching tests
