- Abstract
The sequential extraction procedure of Zinc and lead performed in a Brazilian soil showed that it presents high pollution potential once over 90% of total lead is present in fractions where the metals can be easily mobilized. The fraction contents are as follow: F1 = 174 and 15 mg kg-1; F2 = 3155 and 9.7 mg kg-1 F3 = 99 and 1.6 mg kg-1; Residual fraction = 38 and 5.5 mg kg-1 for lead and zinc, respectively. The comparison with non contaminated soil only Pb2+ concentration is above its intervention reference concentration, 900 mg kg-1.
