“…Ni stress reduced the dry biomass and yield of chickpea (legume) whereas Ni at 150 μg g −1 of soil reduced the plant height and leaf morphology in bean plants (Khan and Khan 2010;Al-Qurainy 2009). Moreover, CA application at 5 mmol kg −1 substantially improved the morphological attributes of Phyllostachys pubescens L. (Zhang et al 2018). The photosynthetic pigment and SPAD values were substantially decreased by Ni stress; however, CA application improved the photosynthetic pigments in M. piperita (Figs.…”

Phytoremediation is considered one of the well-established and sustainable techniques for the removal of heavy metals and metalloids from contaminated sites. The metal extraction ability of the plants can be enhanced by using suitable organic materials in combination with metal-tolerant plants. This experiment was carried out to investigate the phytoextraction potential of Mentha piperita L. for nickel (Ni) with and without citric acid (CA) amendment in hydroponic experiment. The experiment was performed in controlled glass containers with continuous aeration in complete randomized design (CRD). Juvenile M. piperita plants were treated with different concentrations of Ni (100, 250, and 500 μM) alone and/or combined with CA (5 mM). After harvesting the plants, the morpho-physiological and biochemical attributes as well as Ni concentrations in different tissues of M. piperita plants were measured. Results revealed that Ni stress significantly decreased the plant agronomic traits, photosynthesis in comparison to control. Nickel stress enhanced the antioxidant enzymes activities and caused the production of reactive oxygen species (ROS) in M. piperita. The CA treatment under Ni stress significantly improved the plant morpho-physiological and biochemical characteristics when compared with Ni treatments alone. The results demonstrated that CA enhanced the Ni concentrations in roots, stems, and leaves up to 138.2%, 54.2%, and 38%, respectively, compared to Ni-only-treated plants. The improvement in plant growth with CA under Ni stress indicated that CA is beneficial for Ni phytoextraction by using tolerant plant species. Keywords Accumulation . Antioxidant enzymes . Citric acid . Mentha piperita . Nickel . Phytoremediation Significance of research work Reported results provided hopeful outcomes and sustainable fate of Ni phytoextraction. The present study confirmed the ecotoxicity of Ni in M. piperita and the efficacy of CA amendment to enhance the Ni bioavailability in culture media and to alleviate Ni-induced ecotoxicity. M. piperita significantly accumulate Ni under CA amendment as confirmed from the results.

“…Bamboo forests cover an area of 14 million acres in China, and in Sichuan Province alone, they cover 2.8 million acres, ranking it the top in the country [15]. As an important part of the forest ecosystem, bamboo forests have the ecological function of protecting the environment by conserving soil and water [16,17]. In addition, bamboo forests are commonly used for urban landscape greening because of the supply-side structural reform of forestry of China [18].…”

This study illustrated the physiological and psychological effects of watching videos of different durations showing bamboo forests with varied structures. Physiological indicators, including EEG (electroencephalogram), blood pressure, skin conductance, and pulse, were monitored in 180 Chinese university students (mean age: 20.72 ± 2.56 years) while they were watching bamboo videos. Before and after watching the videos, their psychological indicators, including positive and negative moods, were measured using the Profile of Mood States questionnaire. After watching the bamboo videos of different durations, all of the physiological indicators responded to the stimulation after only 1 min. The indicators showed different trends at 1, 3 and 5 min. EEG decreased and then was maintained at a stable level after 1 min, and the high β, low β, and α waves had no significant differences between 1, 3 and 5 min. Blood pressure dropped to a stable state after 3 min, and the decline was significantly different greater after 3 min than after 1 min. Skin conductance increased for 1 to 5 min, and it did not stabilize after a long time (5 min). Pulse decreased after 1 min but increased after 5 min. After watching the videos with bamboo of varying structures, the physiological and psychological indicators showed significantly different changes. Skin conductance significantly increased (mean value: 6.78%), and the amount of sweat was more effectively reduced, thereby reducing tension, when the students viewed videos of sympodial bamboo forests compared with monopodial bamboo forests. Bamboo forests with a higher canopy density (0.83–0.85) could significantly decrease α waves (mean value: 1.50 Hz), relaxing the human body. High β and low β waves showed greater decreases, with tension reduced more effectively, when bamboo forests with a low tilt ratio (< 1.5%) were viewed. Bamboo forests with neat undergrowth could have more beneficial physiological and psychological effects on the human body.

“…If the soil pH is above the pKA value of citric acid, all protons can be released. However, if the soil pH is below pKA, less H+ is released, it means that COO-cannot form ligands with Pb2+ [21]. The conclusion from the analysis, that the higher the concentration of citric acid, the higher the decrease in pH (Figure 27).…”

Phytoremediation of Lead Contaminated Land Using Vetiver zizanoides and Citric Acid as Chelating Agent

2022

Environmental pollution due to hazardous waste in Karangdawa, Margasari, Tegal has an impact on soil and groundwater quality. Lead found in the soil exceeds the permissible standards. It is necessary to recover soil from Lead because it can enter food crops and accumulate in the human body. Phytoremediation is commonly used in land remediation because it’s economical and doesn’t cause secondary environmental problems. One of the ways to optimize Phytoremediation is by using chelating agents. The purpose of the study was to analyze the ability of Vetiver zizanoides and analyze the most optimum dose variation of Citric acid to uptake Lead to the plant. The ability of Vetiver zizanoides and Citric acid as metal chelators in Pb uptake was investigated for 28 days with Citric acid doses of 0.5 g/kg, 1 g/kg, and 2 g/kg. Analysis of Lead concentration in roots, stems, and soil using AAS. From the results of the study, Vetiver zizanoides was able to survive from Lead exposure up to 4979.8 ppm. Application 1 g/kg of Citric acid in the soil, increased the bioconcentration, and bioaccumulation compared to control plants. The results indicated that the addition of Citric acid as a chelating agent could increase the function of Vetiver zizanoides as a phytoremediation agent.
