However, due to the tendency of metal accumulation, metal contents of leafy vegetables need not only to be determined but also estimated health risk for revealing possible health effects on humans.

Concentrations of the elements in octopus do not follow this pattern-Fe is present at a higher concentration than Zn. Sr is present at higher concentrations than Rb in all the species studied except meagre. K and Ca are present at the highest concentrations in all the samples studied, from 0.6–1.3% and from 0.04–0.08%, respectively, followed by Zn, Fe, Sr, Se, and Rb. The results obtained show a similar pattern for the trace elements. The latter technique was used because of its higher sensitivity, because these elements were not detected by EDXRF. We combined two different techniques for determination of the elements-energy-dispersive X-ray fluorescence (EDXRF) was used to quantify K, Ca, Fe, Zn, Se, Rb, and Sr and flame atomic-absorption spectrometry for analysis of Cr, Ni, Cu, Cd, Hg, and Pb. The aim of this work was to determine the concentrations of some essential and toxic elements in the muscle of ten species of commercial fish consumed in Portugal.
