Abstract

This study focused on the accumulations of Pb and Cu in different parts of Arachis hypogaea exposured to each metal separately under laboratory conditions. Three replications and a randomized complete block design were used in this study. About 3.5 kg of air-dried soil was placed into a 17 × 18 cm poly bag, using a soil mixture (loam soil : organic fertilizer : sand) in a 3:2:1 ratio for the different treatments. For the plants exposed to Cu and Pb, approximately 100 ml of solution was applied twice, during weeks 4 and 5 of the flowering stage. The plants were harvested 90 days after germination. Soil samples were also collected to determine the concentrations of Cu and Pb. The accumulation pattern observed was roots > seeds (with hulls) > stems > leaves for both Cu and Pb treated plants, and the control plants exhibited a similar distribution of metals across plant parts. These findings highlight the potential of A. hypogaea as a biomonitor in future research.
