Special Issue Information

Dear Colleagues,

We are pleased to invite you to submit your papers to the Special Issue “Advances in Research on Phytoremediation of Contaminated Soil and Water”.

Human activities and industrial processes release various pollutants into the environment. As a cheap and eco-friendly technology, phytoremediation has gained more and more interest.

This Special Issue aims to publish manuscripts about research related to using phytoremediation technology to clean contaminated soil and water, including basic laboratory experiments, bench-scale research, pilot studies, and/or full-field applications.

In this Special Issue, original research articles and reviews are welcome. Research areas may include (but are not limited to) the following:

  • Using traditional phytoextraction, phytostabilization, and/or phytodegradation processes for pollutant uptake, sequestration, and removal.
  • Chelator or microorganism-enhanced phytoremediation.
  • Applying plant-based biosorbents for pollutant removal.
  • Any field applications of phytoremediation techniques, such as constructed wetland systems for pollutant control.
  • Regulatory, economic, and social topics related to phytoremediation.
  • Methods to recycle or reuse phytoremediation biomass.

We look forward to receiving your contributions.

Dr. Lin Guo
Guest Editor

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. 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. Water 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 2600 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.

Benefits of Publishing in a Special Issue

  • Ease of navigation: Grouping papers by topic helps scholars navigate broad scope journals more efficiently.
  • Greater discoverability: Special Issues support the reach and impact of scientific research. Articles in Special Issues are more discoverable and cited more frequently.
  • Expansion of research network: Special Issues facilitate connections among authors, fostering scientific collaborations.
  • External promotion: Articles in Special Issues are often promoted through the journal's social media, increasing their visibility.
  • e-Book format: Special Issues with more than 10 articles can be published as dedicated e-books, ensuring wide and rapid dissemination.

Potentially toxic metals contaminate the environment and threaten human health. This study investigated the effect of chelator citric acid (CA) on enhancing metals (Cu, Ni and/or Pb) accumulation in duckweed (Lemna minor). Lemna minor were cultured in solutions with single or mixed metals (Ni 50 ppm, Cu 50 ppm and/or Pb 10 ppm) added with different levels of CA (0 ppm, 10 ppm, 50 ppm or 100 ppm CA) for 4 weeks, then harvested, dried and digested. For single-metal solutions, duckweed treated with higher levels of CA (50 ppm or 100 ppm CA) accumulated more Ni or Cu; 100 ppm CA increased Cu and Ni accumulation in plants by 96% and 120%. Meanwhile, 10 ppm CA, 50 ppm or 100 pm CA had similar effects on improving Pb accumulation in duckweed, which enhanced Pb accumulation in duckweed by 100%. For duckweed cultured in mixed-metals solutions, 50 ppm and 100 ppm CA still significantly increased the amounts of Cu and Ni in duckweed by 50% and 100%, while Pb sequestration was not enhanced. The role of CA in increasing metal accumulation in duckweed depended on the levels of CA, the concentrations and types of metals. Future studies are needed to further investigate the potential of CA to assist phytoremediation of different metals contaminated environment. Full article
