Special Issue Information

Dear Colleagues,

The raising of environmental awareness and the willingness to rely on Nature-Based Solutions enhance the importance of phytoremediation. Phytoremediation, or in other words, the use of higher plants to clean up and revegetate contaminated sites such as water, soil, sediments, and the air is an important part of the new field of green engineering. Phytoremediation leads to the mitigation of the advancing climate changes, and their use in urbanized areas improves the ecosystem functions. Individual remediation processes may indicate the effectiveness and tolerance of the plant to specific pollutants (eg. hyperaccumulators of heavy metals or rare earth elements) or cause stress-related response features results with species wilt. Recently, special attention has been focused on the processes taking place in the rhizosphere and the introduction of additives to increase the efficiency of the phytoremediation process. Nevertheless, there is still a need to expand knowledge on the processes, pathways, and capabilities of species specific to a given climatic condition, phytoremediation technologies planning, as well as analysis of the possibilities of using biomass after the performed treatments.

Potential topics of this Special Issue include, but are not limited to:

  • Phytoremediation of soils, sediments, surface waters, and wastewaters
  • Potentially toxic elements uptake and metabolism in plants
  • Phytoremediation of emergent contaminants
  • Recovery of nutrients and useful elements by plants
  • Influencing of stress factors on phytoremediation process
  • Chelators, biochar, and microbes use for phytoremediation efficiency enhance
  • Value-added products produced with plants
  • Management and planning of phytoremediation processes
  • Ecological engineering methods and systems such as constructed wetlands, floating treatment islands, green walls, etc.

Original scientific contributions (case studies, experiments) and state-of-the-art reviews that describe recent advances concerning these topics and closely related areas are welcome.

This Special Issue focuses on diverse aspects related to phytoremediation at all, therefore the published research papers will bridge the gaps and shine new light on processes as well as the application of unrecognized plant species and emerging contaminants in the aspects of environmental protection.

Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Sustainability is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2400 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Soil Arsenic Toxicity Impact on the Growth and C-Assimilation of Eucalyptus nitens

The selection of adequate plants that can cope with species that can live in contaminated/degraded and abandoned mining areas is of utmost importance, especially for environmental management and policymakers. In this framework, the use of a fast-growing forestry species, such as Eucalyptus nitens, in the recovery of arsenic (As) from artificially contaminated soils during a long-term experiment was studied. Roots can accumulate to levels ranging between 69.8 and 133 μg g−1 for plants treated with 100 and 200 µg As mL−1, respectively, while leaves between 9.48 μg g−1 (200 As) and 15.9 μg g−1 (100 As) without apparent morphological damage and toxicity symptoms. The C-assimilation machinery performance revealed a gradual impact, as evaluated through some gas exchange parameters such as the net photosynthetic rate (Pn), stomatal conductance to H2O (gs), and transpiration rate (E), usually with the greater impacts at the highest As concentration (200 As), although without significantly impacting the PSII performance. The As effects on the uptake and translocation of Ca, Fe, K, and Zn revealed two contrasting interferences. The first one was associated with Zn, where a moderate antagonism was detected, whereas the second one was related to Fe, where a particular enrichment in leaves was noted under both As treatments. Thus, it seems to exist a synergistic action with an impact on the levels of the photosynthetic pigments in As-treated plant leaves, compared with control plants. E. nitens must be considered as an alternative when phytoremediation processes are put into practice in our country, particularly in areas with cool climatic conditions. Full article

Industrial revolution has intensified water pollution due to the indiscriminate discharge of untreated industrial effluents into water bodies, posing a serious threat to the whole ecosystem. Recently, the floating treatment wetlands system (FTWs) technique has been used as one of the most innovative, cost-effective and environment-friendly option for wastewater treatment. The present study is aimed at investigating the Malachite green (MG) dye decolorizing potential of Eichhornia crassipes (water hyacinth) through the development of a bacterial augmented FTWs. To an artificial FTWs, vegetated with E. crassipes and bioaugmented with Pseudomonas putida and Pseudomonas sp., synthetically prepared MG dye enriched wastewater was added. Among all the treatments developed, floating wetlands treatment T2 (consisting of dye, E. crassipes and Pseudomonas putida) performed the best in decolorizing the dye and in reducing values of electrical conductivity (EC), pH and total dissolved solids (TDS) of the treated water. Bacterial inoculation proved fruitful in assisting the increased MG dye decolorization in partnership with E. crassipes and also helped in aquatic plant growth promotion. MG dye toxicity effects were studied through phytotoxicity assay using FTWs treated water on Pisum sativum seeds, and satisfactory results were obtained. From experimental results, it can be seen that Eichhornia crassipes with bacterial inoculation have a strong ability to degrade and decolorize MG dye in textile effluents. We conclude that the plant-microbial assisted FTWs technique can be a unique approach to remediate the textile dye effluents before their release into water bodies. Full article
