Abstract
Soils of 2 different types (acid and alkaline) were enriched in Pb and Cd by rising doses of municipal waste compost.
On the acid soil also the pH increased gradually.
While the Pb-content of different vegetables grown on both soils rose with the compost addition, the Cd-content was governed by the soil pH. It increased with the compost dose on the alkaline soil and decreased on the acid one.
The effect of the soil type and of the plant species was much greater than that of the compost dosage.
Up to the highest dose the heavy metal contents of the plants remained below the WHO limits.
On the acid soil also the pH increased gradually.
