Phytoremediation potential of Lantana camara and Polygonum glabrum for Arsenic and Nickel contaminated Soil

摘要

This study was carried out to investigate the potential of Lantana camara and Polygonum glabrum for the accumulation and distribution of arsenic (As) and nickel (Ni) in the different plant organs. The plants and soil samples used in this study were obtained from the places nearby Koradi Lake which is situated to the northern side of Nagpur and then analyzed for arsenic (As) and nickel (Ni) content. The metals accumulated were investigated using inductively coupled plasma atomic emission spectrometer (ICPAES). The arsenic content in soil was 2.29 ppm and that of nickel was 58.344 ppm. The ability of plants to absorb metal from the soil was calculated by bioconcentration factor (BCF) whereas their ability to translocate metal from root to aboveground plant part was calculated by translocation factor (TF). On the basis of bioconcentration factor (BCF) and translocation factor (TF) values, Lantana camara and Polygonum glabrum were identified as potential plants for phytoextraction of nickel and arsenic contaminated soil respectively.
