Human hair is frequently used to monitor the exposure of humans to certain metals, as hair keeps record of past contact due to its sequential growth. Taking samples of hair is pain-free and non-invasive. JRC-IRMM has therefore released ERM-DB001, a new human hair material certified for the mass fraction of the total content of As, Cd, Cu, Fe, Hg, Pb, Se and Zn at the mg/kg range.
ERM-DB001 has been processed and certified in accordance to ISO Guides 34 and 35. It is primarily intended for method validation (e.g. trueness estimation) and performance control within laboratories involved in element determinations in human hair or similar matrices.
Details about material sampling, processing and certification are described in the certification report, available together with the certificate in our online catalogue.
