Abstract
This research aims to study the ability of fava beans (Vicia faba) and basil (Ocimum basilicum) plants to accumulate lead and cadmium elements in the soil of two random dumpsites (near the village of Tal Al-Nasr – near the village of Al-Nuwaiha) in Homs city. Soil samples were collected on (10-9-2018) and were placed in potted planted with the seeds of both fava beans and basil. Plant samples were collected (leaves – roots – seeds) and samples were prepared to determine the concentrations of (Pb, Cd) by means of the flame atomic absorption device brand (Shimadza AA 7000) and the results were expressed in ppm. The element accumulation was estimated by calculating the bioaccumulation factor (BF). The average lead content for two landfillers was (36.82 -15.30 ppm) respectively in different parts of the fava beans plant (grains, leaves, and roots) and the average value of the BF for two landfillers was (BF = 0.210 <1). The average lead content for two landfillers was (16.77-5.93 ppm) respectively in different parts of the basil plant (leaves – roots) and the average value of BF for two landfillers was (BF = 0.08 <1). The average cadmium content for two landfillers was respectively (0.93-0.27 ppm) in different parts of the faba bean plant and the BF for two landfillers was (BF = 0.73), the average cadmium content of landfillers was (1.76-0.28 ppm), respectively in the different parts of the basil plant and the average value of the BF for the two landfillers was (BF = 0.83), therefore we find that all of the fava bean and basil did not provide as a good accumulators of Pb in landfills, while they were good accumulators of cadmium.
Key words: Phytoextraction, Bioaccumulation factor, Fava beans, Basil, Cadmium, Lead.
