Study of trace metal-bearing phases in sediments from runoff water infiltration basins Etude des phases porteuses des polluants métalliques dans des sédiments de bassins d'infiltration des eaux pluviales

The distribution of trace metals (Cd, Cr, Cu, Ni, Pb, Zn) in sediments of two infiltration basins in the area of Nantes (F) was determined using sequential and kinetic extractions associated with mineralogical analysis and SEM observations. The sequential extractions were conducted using the three-steps BCR protocol. The results showed quite similar distribution of trace metals in the two sediments, except for copper. Cadmium is mainly bound to the exchangeable fraction and Cr and Ni are mostly from the residual fraction. The major part of lead lies in the reducible fraction. zinc is concentrated in the exchangeable fractions and reducible. Cu is either mainly in the residual fraction for Boisbonne sediment, or equally distributed in exchangeable, oxidizable and reducible fractions. The comparison with the kinetic extractions let to associate the lability and non-extractability of trace metals to the fractions defined in sequential extractions. The observations by scanning electron microscope have confirmed the XRD analysis on the mineralogical composition of sediments and have highlighted the presence of bulky aggregates.
