Special Issue Information

Dear Colleagues,

Chemical speciation and fractionation of metals occurring in different phases of the marine environment are among the fundamental principles explaining their marine biogeochemical variability and cycles. Although metals’ bioavailability is principally related to their ‘free’ (hydrated) forms, their interactions with the active sites of natural organic chelators effectively control their speciation, hence affecting their mobility, bioavailability, and toxicity.

In an attempt to identify and assess the complex parameters which could provide information on metal species’ levels, several analytical methods and techniques are applied in the different phases of the marine environment. Investigating the speciation/fractionation of metals still remains challenging, under the perspective of giving the best estimate of their bioavailable fractions. Thermodynamic modeling together with specialized sensitive analytical techniques have been applied for the study of metal complexation with chelators, present at low concentrations in seawater. Metals’ fractionation in sediments, which may occasionally act as a source and/or sink of metals, is studied through the application of several schemes targeted at the evaluation of metals’ mobilization and fluxes.

Original, unpublished research papers are invited in this Special Issue, providing innovative insights into advances, novel approaches, and recent findings on the wide aspect of speciation/fractionation of metals in the different phases of the marine environment (dissolved and particulate phases of seawater and sediments). Emphasis is on metal speciation and bioavailability, as well as on current tools applied in their study.

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 papers will be 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. Environments 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 1000 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.
