The Potential of Tabebuya as Phytoremediator of Lead (Pb) in Atmosphere

Abstract

Lead (Pb) is one of the heavy metals that causes pollution in ecosystems, heavy metal Pb can cause disturbances to humans, including plants and animals. In Indonesia, especially in Surabaya, Tabebuya grows on main roads as a shade tree as well as an ornamental plant; This plant can be exposed to Pb metal, among others, from motor vehicle exhaust. This study aimed to determine the levels of Pb in Tabebuya and to study chlorophyll in the leaves. Pb levels in plant leaves were measured using an atomic absorption spectrophotometer (AAS), and chlorophyll levels using a spectrophotometer. Data in the form of Pb and chlorophyll levels at various locations were analyzed by analysis of variance (Anova). The results showed that the location of plant species affected the content of Pb metal and there is no effect of chlorophyll content in the leaves. The results also showed that the absorption of lead (Pb) content by the tabebuia 0.25-0.44 ppm and content of chlorophyll 12.89-14, 94. Lead (Pb) content do not affect the amount of leave chlorophyll produced and the plant had capabilities in absorbing lead like pollutants (Pb).
