“…In connection with global warming that is increasingly evident today, an increase in the earth's surface temperature can increase water evapotranspiration (54) and the earth's surface in the form of aerosols, which carry various physical, chemical and biological substances into the air (55,56). Considering the role of plants in removing pollutants (57,58), the aerosol pathway in the phytoremediation process is described as presented in Fig. 1.…”

Black carbon aerosol is able to absorb solar radiation and the earth's surface, which results in warming of the air. In addition, aerosols that are directly absorbed through inhalation can have a negative impact on human health. Meanwhile, the ability of air to reduce the level of pollution is the deconcentrating of pollutants through abiotic mechanisms in the form of distribution, dilution, precipitation and washing when it rains. To strengthen the abiotic approach, this study aims to develop a biotic strategy by preparing plants capable of deconcentrating black carbon. The research method is based on a literature review, which specifically addresses the issue of black carbon. Literature is collected from the Mendeley platform and enriched through resource searches in open access journals. The results obtained are cleaning priorities for the closest source of aerosol generation, plant placement in priority areas, selection of plant species, intensification of vegetation quality and management of land cover extensification. The contribution of biotic strategies and phytoremediation pathways enhances the aerosol cleaning process. Plant maintenance and regeneration determine the sustainability of aerosol phytoremediation.

“…Its placement in road medians and/or roadsides is effective for deconcentrating aerosols. Its strategic value is mainly to localize the horizontal distribution of aerosols (57,66,67), while the effect of upward scattering of aerosols can be accomplished by air dilution.…”

“…Miscanthus is not only able to replace the fossil fuels as a renewable and clean energy source but also it can play an important role in environmental remediation and ecological improvement (Zhang et al 2020;Wagner et al 2019). Firstly, Miscanthus has the ability to accumulate heavy metals and degrade organic pollutants in the polluted soil.…”

Miscanthus is a tall perennial rhizomatous grass with C4 photosynthesis. Because of its high biomass yield, high carbohydrate and low ash content, high calorific value, remarkable environmental adaptability, high water and land use efficiency, and low fertilizer and pesticide requirements, it has become one of the most promising energy crops. Apart from energy uses, it can also be used as raw material for paper-making and for production of a variety of chemicals. Moreover, Miscanthus can also play an important role in environmental remediation and ecological improvement. It has been used to remedy polluted soil, improve the soil quality, and increase the biodiversity by providing habitat for animals and insects. However, its commercialization is still facing great challenge. More study is needed to further decrease its cultivation, harvesting, and processing costs. This editorial discusses opportunities and challenges of Miscanthus as an energy crop and in other applications.

Heavy metals can represent a threat to the health of aquatic ecosystems. Unlike organic chemicals, heavy metals cannot be eliminated by natural processes such as their degradation into less toxic compounds, and this creates unique challenges for their remediation from soil, water, and air. Phytoremediation, defined as the use of plants for the removal of environmental contaminants, has many benefits compared to other pollution-reducing methods. Phytoremediation is simple, efficient, cost-effective, and environmentally friendly because it can be carried out at the polluted site, which simplifies logistics and minimizes exposure to humans and wildlife. Macrophytes represent a unique tool to remediate diverse environmental media since they can accumulate heavy metals from contaminated sediment via roots, from water via submerged leaves, and from air via emergent shoots. In this review, a synopsis is presented about how plants, especially macrophytes, respond to heavy metal stress and we propose potential roles that phytohormones can play in the alleviation of metal toxicity in the aquatic environment. We focus on the uptake, translocation, and accumulation mechanisms of heavy metals in organs of macrophytes and give examples of how phytohormones interact with plant defense systems under heavy metal exposure. We advocate for a more in-depth understanding of these processes to inform more effective metal remediation techniques from metal-polluted waterbodies.
