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).

Highlights

Heavy metals (Pb, Cd, Zn, Fe) are the main pollutants released into the atmosphere [1]
Research [2] in Indonesia showed that potential to absorb lead (Pb) levels in PM-2,5 and PM-10 in several cities were still relatively high
Taking into account the importance of the role of Pb in polluting the air and the prediction that Tabebuya can reduce Pb levels in the air, it is necessary to investigate the potential of this plant, so the objectives of this study were 1) to analyze the Pb levels in Tabebuya leaves, 2) to analyze the chlorophyll content in Tabebuya leaves. it is not known that

Summary

Introduction

Heavy metals (Pb, Cd, Zn, Fe) are the main pollutants released into the atmosphere [1]. Plant organs and microbes present in the phyllosphere and rhizosphere interact with each other to overcome polluted air [5]. Pollutants contaminate soil and bacteria around plant roots (rhizosphere) This is the main role of plants in reducing air pollutants. This ability will affect the chlorophyll content and growth. Taking into account the importance of the role of Pb in polluting the air and the prediction that Tabebuya can reduce Pb levels in the air, it is necessary to investigate the potential of this plant, so the objectives of this study were 1) to analyze the Pb levels in Tabebuya leaves, 2) to analyze the chlorophyll content in Tabebuya leaves. Research related to this phytoremediator has not been widely disclosed
