Dear Colleagues,

Organic contaminants, whether from natural or anthropogenic sources, are constantly being released into the environment. Consequently, they can be found in all regions around the globe. These contaminants have the potential to impact ecosystems (terrestrial and aquatic) and human health. Given their widespread occurrence and deleterious impacts, they are a matter of global concern.

In order to understand the real extension of this problem and to propose new and effective measures to reduce their deleterious impacts, it is crucial to monitor the emissions, presence, and effects of these organic contaminants. In order to achieve this goal, the different classes of chemicals should be appraised, as well as their distributions in different regions around the globe (including less studied locations, e.g., Africa, Antarctica or the deep sea environment) and in distinct environments (e.g., indoors, occupational settings).

This comprehensive knowledge will allow us not only to provide a clearer picture of the environmental risk associated with these contaminants, but also to evaluate the efficacy of the legislation already adopted and the chemical control efforts under development. It will also provide data on the effectiveness of the different treatment processes to reduce and remove organic contaminants from the environment, with the ultimate goal of protecting the environment and human health.

This Special Issue aims to address all aspects associated with the monitoring of organic contaminants, including the description of their levels in different locations and in different matrices, including air, water, soil, and biota. Exposure assessment studies in humans and domestic and wild animals will also be considered, as well as the analytical aspects of the techniques used. Studies dealing with the development of new methods and the development of reference materials are also 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 papers will be 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. Processes 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 2000 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.
