Résumé
In this study, olive oil samples of different irrigation system in Palestine were studied. The density, refractive index, acidity and viscosity of the samples were measured. The results indicate that acidity increase for samples with trees irrigated by waste water which can be classified as Lampante oil. The experimental results of viscosity showed that the viscosity increased for all samples were irrigated by waste water. The concentration of some metals in olive oil samples irrigated by waste water have high concentration compared with literature. These metals are : calcium, sodium, potassium, magnesium and zinc. The concentrations of iron, copper and lead for irrigated samples by waste water are greater than concentrations of established by standards of IOOC. The presence of these metals in olive oil may be due to the abundance of them in waste water. The concentration of cadmium and manganese found at high concentration for Hawara samples because it is industrial area.
