“…The maximum acceptable intake of Pb in human food is about 25 μg kg −1 of human body weight per week. In soil, Pb content may occur up to 10 ppm (34) but for humans, the maximum permissible range is 0.003 mg/l [7] and 0.005 mg/l by Rani et al [8]. To overcome these issues, remediation of the soil is needed and many approaches are available to reduce the contaminants from the soil but phytoremediation is one of the best remediation strategies.…”

Lead contamination in the agricultural soil by anthropogenic activities, industrialization and modernization poses a great concern to human health. A pot experiment was completed to evaluate the effect of Pb concentrations (0, 150, 500, 1000, 1700 mg kg-1) of lead nitrate on Bambusa balcooa plantlets grown in earthen pots placed in a fenced enclosure. For each concentration, three replicates were taken and to reduce the heterogeneity in the results, pots were placed in randomized manner. Thereafter, plantlets were transplanted in the pots and grown in the natural condition, only rainfall was controlled by covering the fenced enclosure with polythene sheet. The result showed that a higher concentration of Pb caused a minimum increase in the number of culm (0%), nodes (25%), leaves (58.53%), length of internode (19.04%), plant height (32.89%) and leaf area (62.91%). Biomass of the plant ranged from 5.33± 0.57 to 37.33±6.42g and moisture content was found maximum in Pb 500 mg kg-1 (38.78%) throughout the experiment. Findings of the study indicates that B. balcooa can tolerate the elevated level of Pb toxicity and can be used for remediation purpose.

“…The major component responsible for soil contamination is heavy metals [1]. Arsenic (As), cadmium (Cd), chromium (Cr), copper (Cu), mercury (Hg), nickel (Ni) and lead (Pb) are common heavy metals classified as pollutants [2]. Some of them are non-essential and act as pollutants even at low concentrations.…”

The accumulation of heavy metals in water streams and soil is considered a grave environmental threat that impacts plants and animals. Biochar has recently been widely used to overcome the effects of heavy metal contamination in plants and remediate the soil. A pot-trial study assessed the morphological traits of Bambusa balcooa under copper contamination. Each pot (twenty-four earthen pots) was filled with 7.0 kg of soil and spiked with copper sulfate of 0, 300, 600, and 1200 mg kg-1. Of the total, twelve pots were amended with 7% (w/w of soil) bamboo biochar. Plant samples were harvested after one year (365 days) of treatment for biomass estimation. Data was recorded for different growth and morphological traits such as the number of clums, nodes, leaves, internode length, plant height, leaf area, root length, and dry biomass of root, shoot, and leaf to evaluate the impact of copper with or without bamboo biochar on Bambusa balcooa. The results indicated that the higher concentration of copper suppressed growth parameters such as shoot length, internode length, number of leaves, and leaf area; therefore, growth increment was significantly reduced at ) mg Kg‑1 copper-added soil. Biochar diminishes the impact of Cu stress on plants to some extent as at higher concentrations (600 and 1200 mg kg-1) was enhanced root dry biomass (51 and 148%), shoot dry biomass (42 and 57%), and leaf dry biomass (38 and 48%). Thus, results confirm that biochar amendment under Bambusa balcooa reduces the impact of copper contamination on the plant and increases plant growth by improving soil health, suggesting that bamboo biochar application was effective in metal stabilization, thereby, reducing the bioavailability and phytotoxicity of Cu and can help to restore copper-contaminated soil.
