Evaluation of some chelating agents on phytoremediation efficiency of Amaranthus caudatus L. and Tagetes patula L. in soils contaminated with lead

ConclusionsAlthough the results obtained showed thatT. patula would have a better phytoextraction potential thanA. caudatus, it should be noted that due to the Pb behavior in the soil and/or leaching of Pb from the soil columns during the irrigation period the low amounts of Pb absorption by the root and aerial parts of the plants compared to the added doses of Pb(NO3)2 solution to the soil samples, imply the studied plants haven ’t the adequate potential for phytoextraction of Pb from contaminated soils.
