A simple and fast method was developed for the determination of traces of Fe, Mn, Cu, Cr, Ni, Zn and Mo in endive using wavelength‐dispersive x‐ray fluorescence spectrometry. Plants were grown in different sewage sludge compositions for 60 days in greenhouse conditions. Samples were compacted and analyzed after drying, milling and homogenization. The method was validated using certified standard reference materials. The results were compared with those obtained by atomic absorption spectrometry. Good agreement for all elements was obtained. The detection limits were found to be Fe 1, Mn 3, Cu 2, Cr 5, Ni 1, Zn and Mo 3 µg g −1 . These results permitted the evaluation of the potential use of sewage sludge as an agricultural amendment.
