Preferred Abstract (Original): 

 The physical properties such as: density, refractive index, viscosity, and acidity of samples of olive oil from different geographical locations and heights in Palestine were measured. The measured physical properties are in agreement with the international and local assigned value. The concentration of Al, Cd, Cu, Fe, K, Mg, Mn, Na, Ni, Pb and Zn elements in olive oil samples are measured by inductively coupled plasma mass spectrometry ICP-MS. It was found that Magnesium (Mg) is the most concentrated metal detected (294.738-782.968 µg/g), followed by concentration of sodium (Na) (73.401-390.699 µg/g) and potassium (K) (18.473-168.883 µg/g). Concentrations of iron, copper and lead in Palestinian olive oil don’t agree with concentration of International Olive Council (IOC). The differences in concentration in metals of olive oil depend on several factors among the type of olive tree, storage age, height and geographical location. There is a positive relation between the concentration of metals in olive oil and physical properties as density, refractive index, viscosity, and acidity. The daily intake rate of these metals shows no risk to human health according to US Environmental Protection Agency (EPA).
