“…While each method has its own set of advantages and disadvantages, the lack of sufficient literature on various MPs removal procedures makes it impossible to recommend a single method as the best available option. Moreover, it is possible to further investigate the various microorganisms and methods that have been well-established for the removal of other contaminants from the environmental media, which can be used in conjunction with one another [82,83].…”

Microplastics (MPs) are ubiquitous and constitute a global hazard to the environment because of their robustness, resilience, and long-term presence in the ecosystem. For now, the majority of research has primarily focused on marine and freshwater ecosystems, with just a small amount of attention towards the terrestrial ecosystems. Although terrestrial ecosystems are recognized as the origins and routes for MPs to reach the sea, there is a paucity of knowledge about these ecological compartments, which is necessary for conducting effective ecological risk assessments. Moreover, because of their high persistence and widespread usage in agriculture, agribusiness, and allied sectors, the presence of MPs in arable soils is undoubtedly an undeniable and severe concern. Consequently, in the recent decade, the potential risk of MPs in food production, as well as their impact on plant growth and development, has received a great deal of interest. Thus, a thorough understanding of the fate and risks MPs, as well as prospective removal procedures for safe and viable agricultural operations in real-world circumstances, are urgently needed. Therefore, the current review is proposed to highlight the potential sources and interactions of MPs with agroecosystems and plants, along with their remediation strategies.

“…HMM pollution in the soil is one of the most serious dangers to water and soil resources, and therefore to human health. Concentrations as high as 1000 ppm (0.1%) are toxic to plants and microalgae [26]. Water-soluble HMMs can be found in significant quantities in plants and microalgae due to their ability to be absorbed [27].…”

Microalgae are continually exposed to heavy metals and metalloids (HMMs), which stifles their development and reproduction due to the resulting physiological and metabolic abnormalities, leading to lower crop productivity. They must thus change their way of adapting to survive in such a hostile environment without sacrificing their healthy growth, development, reproductive capacity, or survival. The mode of adaptation involves a complex relationship of signalling cascades that govern gene expression at the transcriptional and post-transcriptional levels, which consequently produces altered but adapted biochemical and physiochemical parameters. Algae have been reported to have altered their physicochemical and molecular perspectives as a result of exposure to a variety of HMMs. Hence, in this review, we focused on how microalgae alter their physicochemical and molecular characteristics as a tolerance mechanism in response to HMM-induced stress. Furthermore, physiological and biotechnological methods can be used to enhance extracellular absorption and clean up. The introduction of foreign DNA into microalgae cells and the genetic alteration of genes can boost the bio-accumulation and remediation capabilities of microalgae. In this regard, microalgae represent an excellent model organism and could be used for HMM removal in the near future.

In this study, we analyzed and compared the concentrations of selected metals/metalloids and the antioxidant response of Salix alba L. (white willow) bark in the highly polluted area around the Kosovo A and B thermal power plants. The antioxidant capacity of Salix alba bark was evaluated in terms of the total phenolics, flavonoids, chlorophylls, and carotenoids, while the metal content in the soil and willow bark was analyzed by ICP-OES (inductively coupled plasma optical emission spectroscopy). For total antioxidant level assessment, FRAP, DPPH, and CUPRAC assays were conducted. The mean concentrations of selected elements in soil and willow dry mass range from 15,698.4 mg kg−1 dry mass (soil) to 371.1 mg kg−1 (willow bark) for Al; 37.676 mg kg−1 (soil) to <2 ppb (willow bark) for As; 14.8 mg kg−1 (soil) to 0.62 mg kg−1 (willow bark) for Cd; 24.2 mg kg−1 (soil) to 1.2 mg kg−1 (willow bark) for Cr; 58.8 mg kg−1 (soil) to 9.1 mg kg−1 (willow bark) for Cu; 16,975.68 mg kg−1 (soil) to 385.4 mg kg−1 (willow bark) for Fe; 95.0 mg kg−1 (soil) to 7.9 mg kg−1 (willow bark) for Ni; 185.2 mg kg−1 (soil) to <1 ppb (willow bark) for Pb; and 226.7 mg kg−1 (soil) to 87.7 mg kg−1 (willow bark) for Zn. Additionally, the Salix alba bark samples presented mean values of 12,191.6 mg kg−1 for Ca, 1306.0 mg kg−1 for Mg, and 123.1363 mg kg−1 for Mn. The mean phenolic content was 39.292 mg GAE g−1 DW, being 28.222 mg CE g−1 DW for flavonoids, 38.099 mg g−1 FW for CHLa, 49.240 mg g−1 FW for CHLb, and 94.976 mg g−1 FW for CAR. The results of this study indicate that the bark of Salix alba contains significant amounts of phenolic compounds, and strong positive and moderate negative correlations are revealed between total phenolic compounds and iron, and total phenolics and nickel and manganese, respectively.
