Special Issue Information
Dear Colleagues,
Humankind, particularly all natural sciences branches, is more than ever aware and concerned regarding the environment and health, with the scientific debate of this problem present in many literature publications focused on this topic. Therefore, the question arises whether the analytical laboratories are part of this adverse effect on the environment, or if analytical chemistry can even partially solve the negative impact of chemicals and reagents typically recommended for solving a certain analytical problem. The frequent use of organic solvents, for example, in different analytical procedures such as a part of the analysis known as sample preparation, introduces the discussion regarding their wasted amount and impact on the environment. A desired solution by analysts is to replace solvents having a toxic interaction with others, having a greener effect on the environment, or the development of analytical technologies that avoid common solvents, such as, for instance, the implementation of superheated water chromatography, which is considered to be a green technology compared to the others in use. Another option is to find strategies for a reduction in the consumption or dissipation in the environment of irreplaceable solvents and reagents in laboratories by means of optimization procedures and eliminating unnecessary experiments. Other than more or less harmful solvents, there are many other substances manipulated in analytical laboratories or being used as reagents and additives in different experimental procedures that could potentially increase the risk of adverse effects on the environment, with some implementation possibilities of “green chemistry” rules to analytical laboratories already having been reported by the literature, although this trend keeps accelerating and more interest is being dedicated to this sensible field of research. Additionally, in recent decades, the literature has recommended different green metric approaches that could be used to evaluate the environmental effects of analytical procedures. Therefore, it is the aim of this Special Issue of Molecules to provide some contributions to this topic, by discussing the actual problems and possible solutions in research papers or reviews by chemists and their collaborators involved in environmental aspects and related domains.

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. Molecules 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 2700 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.
