Special Issue Information

Dear Colleagues,

Emerging contaminants (ECs) are harmful chemicals that may cause ecological or human health impacts, and typically are not regulated under current environmental laws. They occur in the environment on a global scale and encompass a huge number of lifestyle compounds, ranging from organic and inorganic compounds to nanoparticles. There are four major categories of ECs that are widely of concern worldwide: persistent organic pollutants, endocrine disruptors, antibiotics, and microplastics. These substances have been documented regarding their biotoxicity, environmental persistence, bioaccumulation, and widespread detection in aquatic systems, raising concerns about the possible adverse effects on human health. Thus, the surveillance of ECs and the assessment of the risk they pose to ecosystems is pivotally important. This Special Issue aims to better understand the exposure to ECs, the risks such contaminants may pose to human health, and how that information can inform policy and regulation. Areas of interest for this Special Issue include but are not limited to:

  • Occurrence, transport, and fate of ECs in the aquatic environment.
  • Toxicity of ECs to aquatic organisms.
  • Exposure and effect assessment of ECs for human health.
  • Studies assessing health effects of real-world exposure to ECs.
  • Combined toxicity of ECs.
  • Quantitative structure–activity relationships (QSARs) of ECs.

Original research articles and reviews are welcomed. I look forward to receiving your contributions.

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. Toxics 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.

Abstract
The levels of essential (Cu, Cr, Co, Mn, Se, Zn) and non-essential (As, Be, Bi, Cd, Cs, Ga, Ni, Pb, Sr, Tl, U, V) trace elements were studied in razor clams (Solen marginatus) collected from the Tyrrhenian coast of Southern Italy [...] Read more.
The levels of essential (Cu, Cr, Co, Mn, Se, Zn) and non-essential (As, Be, Bi, Cd, Cs, Ga, Ni, Pb, Sr, Tl, U, V) trace elements were studied in razor clams (Solen marginatus) collected from the Tyrrhenian coast of Southern Italy at five selected sites along the Domitio littoral in the Campania region. The main objectives of this study were to assess the contamination status of these bivalve mollusks and to evaluate the risks to the environment and consumers due to metal contamination. The concentrations of 18 trace elements were determined after microwave-assisted mineralization and by inductively coupled plasma mass spectrometry (ICP-MS). Concentrations of the toxic elements Pb and Cd were below the maximum levels established by Commission Regulation (EC) 1881/2006, while higher average concentrations of arsenic were found at each of the five sites studied. Regarding the other trace elements, contamination levels followed the order: Zn > Sr > Mn > Cu > Se > Cr > V > Ni > Co > Ga > Cs > Be > U > Bi > Tl. No significant differences among the sites were found with regard to any of the trace elements analyzed, and element levels in razor clams did not reflect sediment contamination. The results demonstrated the substantial food safety of the razor clams in this area with respect to heavy metals but revealed a potential health risk due to arsenic contamination in all the areas sampled.
