The determination in olive oils of the legislated metals (As Cu Fe and Pb) by the International Olive Oil Council (IOC) has been carried out by inductively coupled plasma mass spectrometry (ICP-MS) following microwave digestion with nitric acid The method has been validated using an oil reference material and by recovery experiments obtaining in both cases satisfactory results The detection limits achieved are 09 15 30 and 40 ng g(-1) for Pb Cu As and Fe respectively These limits are much lower than the Maximum Residue Levels permitted The four trace metals have been determined in different categories of olive oil fit for consumption by IOC (extra virgin olive oil virgin olive oil olive oil and pomace-olive oil) observing a high content of Cu in pomace-olive o
