Using energy dispersive X-ray fluorescence analysis with an X-ray tube filt
ered with Ti, it was possible to determine the concentration at ppm level o
f several elements (K, Ca, Ti, Mn, Fe, Cn, Zn, Ga, Br, Rb, Sr, Zr, Y and Pb
) in soil treated with organic compounds of urban garbage. It was possible
to observe a significant increase in the contents of K, Ca, Zn, Rb, Sr, Zr
and Pb in the soil treated in comparison with the soil control. (C) 2000 El
