Abstract

bstract The assessment of heavy metal composition in medicinal plants is essential due to their potential health implications. This study evaluated the concentration of selected heavy metals in the root, bark, and leaves of Syzygium species using standard analytical techniques such as Atomic Absorption Spectrophotometry (AAS). The metals analyzed included lead (Pb), cadmium (Cd), chromium (Cr), copper (Cu), zinc (Zn), iron (Fe), and nickel (Ni). Results revealed that all plant parts contained detectable levels of both essential and toxic heavy metals, with significant variation among tissues. Leaves generally exhibited higher accumulation of certain metals such as lead and zinc, while bark and roots showed relatively higher concentrations of iron and copper. This variation may be attributed to differences in physiological roles and environmental exposure of plant parts. Similar studies indicate that plant tissues can differentially accumulate heavy metals depending on environmental conditions and plant metabolism.
