Total reflection x‐ray fluorescence (TXRF) spectrometry was applied after sequential leaching for the speciation of selected elements in particulate matter, in order to complete the knowledge of the mobility of the selected elements and to determine which components are harmful to works of art. Samples were collected on filters in two churches, one situated in a rural area and the other in an urban area. A five‐stage sequential leaching scheme for the speciation of K, Ca, Fe, Zn and Pb was applied, the fractions obtained being as follows: exchangeable elements; elements bound to carbonates; elements bound to Fe and Mn oxides; elements bound to organic matter; and the digested insoluble residue. It was found that, in the case of the church in the urban area, much of the K, Fe and Zn appeared as mobile elements, whereas for the church situated in the rural area, the amounts of Ca and Fe were most mobile.
