Special Issue Information

Dear Colleagues,

Soil and water are precious resources that support most animal and plant species globally. Trace elements in ecosystems come from mineral origins and anthropogenic sources. Moreover, the cycling of trace elements is through crucial processes controlling life on our planet, particularly for the transfer of these elements in soil and water. Factors controlling the ecological, geological, and chemical processes of trace elements in soil and water are becoming attractive to achieve the Sustainable Development Goals (SDGs). Thus, providing up-to-date knowledge on trace elements in different soils and water bodies worldwide is crucial for the planet’s security because these environments act as sources and sinks for nutrients and contaminants including trace elements.

The Special Issue will gather high-quality papers focusing on different aspects and findings of ecogeochemical processes of trace elements in soil and water-related to their uptake by animals and plants. However, topics dealing mainly with soil and water remediation techniques will not be considered for this Special Issue because this area has already been extensively explored.

Submitted contributions will go through a peer-review process performed by independent reviewers. Original case studies and review papers are invited for publication in this Special Issue.

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 2200 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.

Chromium (Cr)(VI) is carcinogenic; thus, the excessive presence of Cr(VI) in soils can pose potential risks to water quality, food safety, and human health. The kinetics of Cr(VI) reduction in soils are important for assessing the fate of Cr in the environment. The present study tested physio-chemical and microbial properties in twenty-eight agricultural soils collected in Taiwan to evaluate the relationship between the reduction rate of Cr(VI) and soil properties, using 49-day incubation at 25 °C. At the beginning of incubation, 100 mg Cr(VI) kg−1 was spiked into the soils. The reduction of Cr(VI) was described by first-order kinetics at a significant level (p < 0.05) for the tested soils. The rate constant (k) of Cr(VI) reduction ranged from 0.01 to 4.21 day−1. In addition, the k value significantly increased with organic carbon (OC) and cation exchange capacity, but significantly decreased with increasing pH and dithionite-citrate-bicarbonate extractable Mn (Mnd). However, a predictive model using stepwise regression analysis indicated that the k value of the kinetics was controlled by OC, dissolved organic carbon (DOC), and Mnd, thereby identifying the complex interactions between Cr(VI) reduction and soil factors in the humid tropics.
