One of the three major heavy metals which can be harmful to plants, animals, and humans is lead (Pb). Smoke from gasoline fueled motor vehicles become the sources of these pollutants. In plants, including Tabebuia aurea can be found in the roads that are often passed by vehicles, so lead exposure is unavoidable.The purpose of this research was 1) to analyze the lead levels in T. aurea leaves, 2) to analyze the chlorophyll levels in T. aurea leaves, 3) to analyze the growth (leaf area). The Pb level in plant leaves was calculated using AAS (Atomic Absorption Spectrophotometer), chlorophyll level using spectrophotometer, growth was measured with leaf meter. Data were analyzed by descriptive and Anova. Based on the research and analysis that have been carried out can be concluded that 1) Pb metal levels 0.09 – 0.187 mg/L, 2) leaf chlorophyll levels ranges from 2.719 – 7.594 mg/L, and 3) Leaf area ranges from 186.720 – 199.288 cm2.Analysis with Anova ahows that the sampling location affected the Pb and chlorophyll content in the leaves,while the location did not affect the surface area of T. aurea leaves. The results of this research indicate that T. aurea can be used as a plant to absorb Pb pollutants in the air.
Key words: Lead (Pb) / Tabebuia aurea / Air Polluted / Anova
