Abstract

A field study was carried out to evaluate long-term heavy metal accumulation in the top 20 cm of a Tunisian clayey loam soil amended for four consecutive years with municipal solid waste COMPOST at three levels (0, 40 and 80 t/ha/y). HEAVY METALS uptake and translocation within WHEAT PLANTS grown on these soils were also investigated. Compared to untreated soils, COMPOST-amended soils showed significant increases in the content of all measured metals: cadmium, chromium, copper, nickel, lead and zinc in the last three years, especially for plots amended with municipal solid waste COMPOST at 80 t/ha/y. WHEAT PLANTS grown on COMPOST-amended soils showed a general increase in METAL UPTAKE and translocation, especially for chromium and nickel. This heavy METAL UPTAKE was about three folds greater in plots amended at 80 t/ha/y as compared to plots amended at 40 t/ha/y. At the end of the experimental period, the diluting effect resulting from enhanced growth rates of WHEAT PLANTS due to successive COMPOST applications resulted in lower concentrations in the plants (grain part) grown on treated plots. On the other hand, chromium and nickel were less mobile in the aerial part of WHEAT PLANTS and were accumulated essentially in root tissues. Plant/soil transfer coefficients for COMPOST-amended treatments were higher than threshold range reported in the literature, indicating that there was an important load/transfer of metal ions from soils to WHEAT PLANTS.
