Special Issue Information

Dear Colleagues,

Soils all around the world have suffered from years of diffuse and point-source contamination with a wide range of contaminants. Potentially toxic elements (PTEs) represent a major group of contaminants affecting agricultural soils, and the pressure to increase agricultural production has intensified the use of fertilizers, pesticides, and waste-derived amendments which contribute to the introduction of PTEs into agricultural soils. Solutions are urgently needed to prevent further soil pollution, but also to find how to produce healthy food from low-quality agricultural soils, while avoiding the risk of PTEs entering the food chain. Understanding the behavior of PTEs in the soil–plant system and how to control their bioavailability is crucial to find appropriate/successful coping strategies.

This Special Issue aims to cover new studies and approaches concerning agricultural soil contamination with PTEs, including concentrations, emerging PTEs, legal limits, soil–plant system behaviors, effects on soil biota, risk evaluation, practices to prevent soil contamination and mitigating the risk, strategies to control bioavailability, and agricultural soil remediation.

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. Agronomy is an international peer-reviewed open access monthly 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.

Rare earth elements (REEs) and 18 other elements in the vegetables (carrot, parsley, cabbage, potato, onion) and soils from two villages near tailings management facilities in the Baia Mare area, NW Romania, were measured. The soil-to-plant transfer and the health risks posed by the consumption of these vegetables were also assessed. The pseudo-total concentrations of elements varied widely in the soil and vegetables, with the lowest concentrations being found for Ta (2.1 µg/kg) and the highest for Fe (9219 mg/kg). The concentration of total light REEs (LREEs) was considerably higher than that of heavy REEs (HREEs). The percentages of available elements were <20% of the pseudo-total concentration, except for Zn, Cd, and Pb, where the available fractions were much higher. Generally, the soil-to-plant transfer factors decreased in the following order: parsley > onion > cabbage > carrot > potato, and varied from element to element. The LREEs were less absorbed than the HREEs in all investigated vegetable species. Pearson correlations revealed strong positive correlations between the lanthanides, except for Eu, in the soil and vegetables. No important health risks following the consumption of vegetables were found for REEs, the estimated daily intake of REEs through vegetable consumption being much lower than the acceptable daily intake.
