Special Issue Information

Dear Colleagues,

We are organizing a Special Issue of Sustainability on “Analytical Technologies and Processes for Environmental Protection and Food Safety”. The venue is a peer-reviewed open-access journal that publishes articles and communications in the interdisciplinary area of sustainability. For detailed information on the journal, we refer you to https://www.mdpi.com/journal/sustainability.

This Special Issue (SI) focuses on current research on the risks posed by emerging contaminants’ occurrence in substantial compartments of the environment as well as dietary paths. Studies involving processes for the risk characterization and the relevant protection technologies are also encouraged for publishing. This SI focuses on promising and up-to-date studies that contribute directly to the aquatic ecosystem’s or the consumer’s health preservation. Consequently, complete physical, mental, and social well-being is sustained.

In recent years, the development of the urban environment and industry has led to growing pollution in the aquatic environment, ecosystems, wildlife, and food products, which ultimately leads to humans as final recipients. Nowadays, research interest is focusing on several emerging organic pollutants along with their transformation products (TPs) that may be present in the aquatic environmental ecosystems, ground and drinking water, wastewater treatment plants, aquaculture surrounding the environment, and several food commodities such as dairy, agricultural, and aquaculture products. Emerging contaminants mainly include pesticides, pharmaceuticals/antibiotics/psychiatric drugs, endocrine disruptors, personal care products, organic dyes, microplastics, disinfection by-products, and persistent organic chemicals. Monitoring studies on these pollutants are increasingly crucial, and among the detection techniques used, high-resolution mass spectrometry (HRMS), based on “at-the-edge” technology, is in great prominence. Furthermore, a better understanding of contaminants’ fate can introduce the development of sustainable processes and strategies in order to ensure environmental protection.

Our purpose by editing this SI is to collect and disseminate scientific knowledge on advanced environmental and food production issues of great concern. Therefore, we welcome submissions of research articles covering the aforementioned topics or other relevant issues. The listed keywords propose just a part of the many relevant aspects of this broad topic.

We are looking forward to your contributions to this Special Issue of Sustainability.

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. Sustainability 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 2400 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.

Traditionally, antibiotics have been used to treat human and animal diseases caused by pathogenic bacteria. The aquaculture industry, which is massively expanding currently, also makes use of several antibiotic classes, resulting in potential antibiotic residues in the surrounding aquatic environment, as well as the cultured products raising bacterial resistance. The aim of this study was the optimization, validation, and application of a solid-phase extraction (SPE) method in combination with liquid chromatography (LC)-LTQ/Orbitrap mass spectrometry in order to determine the most commonly used antibiotics in waters sampled from fish farms, both saltwater and freshwater, located in Greece. Under optimum conditions, the method was validated, achieving recoveries in the range of 57.7% (for sulfamethoxazole in river water) to 95.8% (for florfenicol in river water). The method quantification limits were within the range of 0.25 and 10 ng·L−1 in all cases, with relative standard deviations (RSDs) < 15.9%. The application of the proposed methodology revealed the presence of oxytetracycline and trimethoprim traces. Finally, an assessment of the environmental risk posed by the detected antibiotics was performed, calculating either the risk quotient (RQ) for three trophic levels (8.013 × 10−6 < RQ < 0.496) or the mixture RQ (0.005 < RQ < 0.682), proving that in all cases, the risk was medium to low.

The aim of this study was the optimization of the clean–up step in the widely applied QuEChERS method for the determination of 39 representative multiclass pesticides in olive oil with Ultra-High-Performance Chromatography–Orbitrap Mass Spectrometry (UHPLC-Orbitrap-MS). The analytical methodology combines the original version of QuEChERS extraction with two different clean-up-step approaches, using firstly a combination of Z-Sep+, PSA and MgSO4 and secondly EMR-lipid. The methods were compared for their efficiency in the removal of fats and co-extractives and their effect on the analytical performance characteristics. Both methods were evaluated in terms of linearity, matrix effects (ME), recovery, precision, limits of detection (LOD) and quantification (LOQ) and expanded uncertainty in three spiking levels of 30, 100 and 300 μg/kg. The recoveries ranged between 70–113% for 95% of analytes (RSDr < 14%) when EMR-lipid was used as a sorbent, while in the case of Z-Sep+/PSA/MgSO4 recoveries ranged between 72–107% for 92% of analytes (RSDr < 18%). ME showed low signal suppression for 77% of analytes in the case of Z-Sep+/PSA/MgSO4 and for 85% of analytes in the case of EMR-lipid. According to the results, both methodologies provided good analytical performances fulfilling validation criteria; however, the EMR-lipid sorbent showed better clean-up capacity (i.e., less matrix effects and lower variability in extraction recoveries) and validation parameter values for more analytes. The validated method was successfully applied to 30 olive oil samples from different regions of Greece. No residues have been identified in the analyzed samples. Full article
