Abstract
Three plants species Helianthus annus, Zea myas and Lepidium sativum were used to study the effect of N, P and K fertilizers on zinc and lead concentration. Plants biomass and plants height and concenration of zinc and lead were determined for the three plants in response to Zn and Pb application. The results showed that the plants height was not negatively affected by the zinc and lead application as compared to the controls, and the increasing in plants’ height in presence of P is very clear. The growth of plants which is expressed as biomass dry weight was not found to be influenced by Zn and Pb application. Biomass yields in plants with the presence of P showed that the results were higher than other plants. The results of zinc and lead concentration showed that the K was the most effective fertilizer for enhancing Zn and Pb concentration by the three plants. In general, the presence of K enhanced Pb concentration in L. sativum very clearly and the presence of K was increased Zn concentration in Z. myas. On the other hand, P and N fertilizers were not influenced in a clear way on the plants concentration of Pb and Zn. Also the results showed that the L. sativum (Brassicaceae) was the most promising for phytoremediation of contaminated sites with Pb in the presence of K.
