摘要

Concentrations of cobalt, nickel, cooper, zinc and lead in the top-soils (0-10 cm) from a former Havana solid waste open dump were estimated by X-ray fluorescence analysis. The mean metal contents in the dump topsoil samples (in mg kg(-1): 8.4 +/- A 2.7 for cobalt, 50 +/- A 27 for nickel, 252 +/- A 80 for copper, 489 +/- A 230 for zinc and 276 +/- A 140 for lead) were compared with mean concentrations from Havana urban soils and from other solid waste disposals around the world. The comparison with Dutch soil quality guidelines showed a serious cooper contamination and a slight contamination with the rest of determined metals. The values of the integrated pollution index (mean index = 3.5) indicated that dump soils are highly contaminated by metals, and the enrichment index values shows that metal concentrations on the studied locations are above the permissible levels for urban agriculture.
