 Abstract
The paper presents the results of preliminary test in lead, copper and zinc determination in contaminated soil samples using an X-ray fluorescence portable instrument. From this preliminary work is evident that portable instrument could be used for the determination of these heavy metals in contaminated soil samples, the correlation factors with laboratory analysis being : 0.82, 1.19 and 1,00, respectively. The analysis time (using XRF instrument) practically do not affect the determination of lead and zinc, but it influence copper determination, especially when small concentration of copper must be determined.

 Rezumat
Lucrarea prezinta rezultatele preliminare obtinute in masurarea concentratiei plumbului, cuprului si zincului din probe de sol poluat, folosind un instrument portabil bazat pe fluorescenta de raze X.
Lucrarile efectuate au evidentiat influenta timpului de masurare asupra marimii rezultatelor in cazul determinarii celor trei metale.
Au fost determinati factorii de corelare dintre rezultatele analizei de laborator si rezultatele XRF pentru plumb, cupru si zinc, valorile obtinute fiind de 0.82, 1.19 si 1.00, respectiv.
