Abstract


Fruit and oilseeds have a primarily role in the development of the human body by high contents of essential fatty polyunsaturated acids (linoleic and linolenic), and also trace elements and mineral elements. Contamination with heavy metals is carried from the soil and atmosphere. It was assess the level of microelements and heavy metals in oil fruits and nuts with tough shell (false): pistachios, almonds; nuts with hard-shell (real): nuts, peanuts, nuts from the ground and oilseeds: pumpkin seeds, sunflower seeds, using a device for X-ray fluorescence ARL Quant type X EDXRF analyzer.
This type of device has the advantage of being non-destructive, multi-element, quickly and efficiently. In addition, a detection limit fairly uniform in a large part of the periodic table and apply a wide range of concentrations, from 100% to a few parts per million (ppm). Its main disadvantage is that the tests are generally limited to elements heavier than fluorine.
