Dear Colleagues,

The development of our civilization is directly associated with the production of various chemical compounds, which often constitute an indispensable part of our everyday life. Examples of such compounds include fuels, pharmaceuticals, polymers, pesticides, and many more. At every stage of their production and usage, there is the danger of their unintentional release into the environment. In addition, many of these xenobiotics are deliberately applied into water or soil to achieve specific effects. In consequence, the natural environment is subject to an increasing threat of anthropogenic pollution. The growing environmental awareness combined with the sustainable development policy dictate the necessity to clean up the contaminated sites. To date, numerous physicochemical methods have been used for this purpose; however, in view of the recent changes in legislation, there is a notable interest in the use of biological methods either as sole treatment processes or as additional support to non-biological remediation. Moreover, recent years have shown the superiority of biological methods, which are still the cheapest and, above all, the most environmentally friendly approaches to decontamination. The progress of biodegradation processes must be monitored using a number of analytical techniques that will enable the precise tracing of the fate of pollutants in the examined environment.

The purpose of this Special Edition is to present the latest work regarding the use of microbiological as well as analytical methods applied during the remediation of contaminated environments. Taking into account the complexity and interdisciplinary character of environmental issues, this Special Edition is also an excellent opportunity to integrate the international society—to share our experiences, provide valuable guidelines, and improve our understanding of the underlying mechanisms. May our joint efforts result in the recognition of future challenges and introduction of efficient solutions.

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.
