Special Issue Information
Dear Colleagues,
An enormous number of various compounds—from the vapors of heavy metals and inorganic gases to the most complex organic and bioorganic compounds, including entire microorganisms—enters the Earth’s atmosphere and water reservoirs every day. The number of known priority pollutants and emerging contaminants of environmental concern currently exceeds several thousand (US EPA Part 423, US EPA Part 401). It grows every day as new pollutants enter the environment (NORMAN List of Emerging Substances). This expanding list can also include their metabolites and degradation products, as well as reaction products occurring due to numerous atmospheric and aquatic reactions. In some cases, these products may even be more toxic than their parent compounds. Therefore, it becomes more and more challenging to conduct comprehensive screening for known and emerging environmental contaminants. Today, various laboratories all over the world work on the identification and quantification of environmental pollutants and contaminants using more and more powerful approaches and analytical tools. In the majority of these studies, a targeted approach is used, when the investigators know, a priori, what they are trying to detect. An alternative, non-targeted approach involves attempts to identify all the chemical compounds in the samples. The latter represents a challenging task, although it allows the establishment of novel contaminants and the finding of peculiarities of the pollution in certain territories of the planet. On the basis of these studies, local lists of priority pollutants can be created, followed by the establishment of the sources of these pollutants and development of adequate policies to address those sources.
The proposed Special Issue of Molecules will cover the results of studies of environmental pollution with various compounds, from the Arctic to Antarctic, with modern analytical tools. Besides those of direct air samples, the results of analyses of snow, rain, fog, cloud water etc.—indirectly revealing atmospheric pollution—as well as studies on water and soil contamination are welcomed

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.
