Abstract

     Heavy metal contamination has been a problem for decades because of agricultural and industrial activities. Among heavy metals, lead (Pb) is a potential pollutant that is accumulated in the soil. Many phytoremediation studies have been made to find the most efficient method in the extraction of this metal. For this purpose, this study investigated the accumulation capacity of yard long beans to 3000 ppm lead. After six weeks of germination, the plants were harvested, air-dried, and prepared using the Acid Digestion Method. The samples were tested for lead absorption using the Atomic Absorption Spectrophotometer (AAS) and were statistically analyzed using one-way ANOVA. Results showed that the application of 3000 ppm lead reduces the plants’ height by 5.26%. The plant can also accumulate an average of 0.50ppm lead nitrate. In conclusion, the plant’s size is not significantly affected by lead concentration. This character inhibited by yard long beans suggested their potential as a phytoremediating agent to lead.
