HSE: MDHS 91 Metals and metalloids in workplace air by X-ray fluorescence spectrometry
Note 1: This MDHS aims to guide those who wish to measure metals and metalloids in air using X-ray fluorescence spectrometry (XRFS) for the purpose of
monitoring workplace exposure. It incorporates, improves upon and replaces MDHS 7 'Lead and inorganic compounds of lead in air',1 MDHS 11 'Cadmium and
