However, amounts of Cd, Cr, Mn, Ni, and Zn exceeded EU standards, although concentrations of Cu and Pb were still within allowable bounds. Maize plants had moderate amounts of Cd, Cr, Cu, Mn, Ni, Pb, and Zn, with Cd concentrations above the EU limit. However, in comparison with compost from waste sites and cultivated soil, other metal concentrations were often lower. Comparable amounts of Cd, Cr, Cu, Mn, Ni, Pb, and Zn to maize plants were also observed in spinach vegetable samples, with Cd concentrations surpassing the EU limit. In average, spinach has greater metal concentrations than maize plants, but lower than compost from trash sites.
