Food chain contamination is one of the major routes for entry of metals into the animal system. Vegetables take up Hg, Pb, Cd, Zn, and Cu, and accumulate them in their edible and inedible parts at various concentrations. In order to study the phytotoxic effect of the major heavy metals (HM) found in compost, in the present work an exhaustive study of the HM composition of six composts from various sources was carried out and correlated with the data obtained from biological tests. The composts from vegetal sources showed the lowest quantities of HM, whereas composts from urban waste gave the highest. Significant negative correlations were found between biological tests carried out with Lepidium sativum L. (cress) and the concentrations of Zn and Cu, and between the tests carried out with Hordeum vulgare L. (barley) and the concentrations of Pb and Cr. |
