| Abstract: | An experiment was carried out in a greenhouse to evaluate the effect of contaminated soil by zinc industry wastes in heavy metal levels and in root and shoot nutritional status of young willow plants. One year old plantlets were transferred and cultivated for thirty days in 6 L pots containing 0, 15 e 30 % (v/v) of contaminated soil with (mg kg-1 soil) 18600 of Zn, 140 of Cd, 450 of Cu and 410 of Pb. Plants grown in this contaminated soil showed high levels of metals in leaves, ranging from (mg kg-1 DW): Zn = 362 to 878 and Cd = 19 to 35, and exhibited Zn and Cd phytotoxicity symptoms. Except for Mn, Fe and S; nutrient (P, K, Ca, Mg and N) levels in plants were not affected by the contaminated soil, showing a low heavy metal influence on their nutritional status. |
