“…Basil, known by the -king of the herbs‖ (Mishra and Chandra, 2022) can treat several diseases and disorders in man and animals (Dhama et al, 2021). This aromatic herbmaygrow and tolerate high levels of PTEs in soil (Mishra and Chandra, 2022), and is considered a good example of contaminant phytoextractors .…”

Elevated levels of potentially toxic elements (PTEs) in soil possess a potential threat to human health. Probably, the use of hyper-accumulator plants can be an eco-friendly and cheap approach to attain more desirable levels of these contaminants in soil. The current study is a trial to increase the efficiency of basil (hyperaccumulator) plants to phytoextract some PTEs, namely Cd, Pb and Co froma clay soil artificially contaminated with these PTEsby the aid of elevated doses of humic acids (HAs 0-50mg kg -1 ) derived from a mature compost. A greenhouse experiment was conducted in 2021to attain this aim and lasted for 60 days, following a complete randomized design. During this investigation, soil moisture was kept gravimetrically ataround 70% of water holding capacityto avoid the leach out of soluble metal ions or organic complexes from the soil. By the end of this experiment, plants were harvested and the results indicated significant reductions in root and shoot dry weights and their lengths owing to the application of humic acids at a rate of 20mg kg -1 versus the control (0 mg HAs kg -1 ). Increasing the dose of HAs application (up to 50mg kg -1 ) led to concurrent significant increases in the abovementioned growth parameters; yet, their values were still below the control plants. Likewise, significant increases were noticeable for PTEs contents within roots and shoots of plants treated with 20mg HAs kg -1 while increasing the dose of HAs application resulted in significant reductions in their contents versus the lower application dose of HAs. Root-to-shoot translocation factor was >1 for each of Cd and Co, while the corresponding values for Pb were less than one. Unfortunately, all BAF values were below one and this result indicates that basil plants cannot be considered hyperaccumulators for Cd and Co but can be used for successful facilitated phytoextraction of these two contaminants from soil. In conclusion, humic acids although enhanced phytoextraction of the PTEs under study by basil plants,yet they cannot beconsidered the optimum chelating agent that could facilitate the phytoextraction of soil contaminants under conditions of the soil under study.

“…Ex situ methods can be applied for contaminated areas, including extraction for treatment through physicochemical methods; however, all these technologies involve expenses, labor, and long-term operating costs. Otherwise, in situ tools are associated with the use of plants and microbiological mechanisms associated with the rhizosphere to degrade contaminants (Mishra and Chandra 2022;Susarla et al 2002).…”

The contamination of soils and groundwater has attracted worldwide attention, since many contaminants are poorly biodegradable and can accumulate in living organisms, causing implications for plants, animals, and human health. The high cost of conventional remediation processes stimulates research for the development of innovative and more sustainable techniques. Likewise, phytoremediation is a cheap technology that uses plants to absorb, transform, and detoxify contaminants through in situ (phytoextraction, phytotransformation, and phytovolatilization) and ex situ mechanisms (phytostabilization and phytostimulation). Recently, phytoremediation has been adopted as a more profitable technique than physicochemical processes. Otherwise, the existence of variables, such as interactions between climate, soil, and plants, requires analysis methods for its implementation, which ensure the reduction of time and cost and improve its efficiency. Research on the application of different phytoremediation techniques is still in progress, and therefore, this study evaluated the main advantages of phytoremediation through a literature overview, comparing the most adequate remediation models in terms of economic, social, and environmental aspects. Highlighted Conclusions1. Phytoremediation consists of the use of plants and their associated microbes for environmental cleanup and recovery of contaminate soil. 2. Phytoremediation promotes social-economics benefits comparing to the conventional techniques, and ensures sustainability in environmental rehabilitation.

“…Also, metals are present in environmental compartments in different sizes, from small particles to large masses [6]. Herbs are even considered a good choice for phytoremediation, as they are grown primarily for processing and also have the capacity to accumulate and eliminate heavy metals from environment, as well as to reduce risks on human health [19,20]. Angelova [21] used Lavandula angustifolia (lavender) in phytoremediation and the results showed that heavy metals accumulated by this species are not transferred in the essential oils.…”

Accelerating heavy metal pollution is a hot issue due to a continuous growth in consumerism and increased activities in various global industries. Soil contamination with heavy metals has resulted in their incorporation into the human food web via plant components. Accumulation and amplification of heavy metals in human tissues through the consumption of medicinal plants can have hazardous health outcomes. Therefore, in this critical review we aim to bring together published information on this subject, with a special highlight on the knowledge gaps related to heavy metal stress in medicinal plants, their responses, and human health related risks. In this respect, this review outlines the key contamination sources of heavy metals in plants, as well as the absorption, mobilization and translocation of metal ions in plant compartments, while considering their respective mechanisms of detoxification. In addition, this literature review attempts to highlight how stress and defensive strategies operate in plants, pointing out the main stressors, either biotic or abiotic (e.g., heavy metals), and the role of reactive oxygen species (ROS) in stress answers. Finally, in our research, we further aim to capture the risks caused by heavy metals in medicinal plants to human health through the assessment of both a hazard quotient (HQ) and hazard index (HI).
