Special Issue "Bioindicators in Air Pollution Monitoring"

Dear Colleagues,

The use of cosmopolite organisms to assess pollution has developed notably over the last few decades. Bioindicators include biological processes, species, or communities and are used to assess the quality of the environment and how it changes over time. Changes in the environment are often attributed to anthropogenic disturbances (e.g., pollution and land-use changes) and natural stressors, although anthropogenic stressors form the primary focus of bioindicator research. Such organisms consume environmental contaminants and may be used as indicators of the bioavailability of a given contaminant over time, allowing, in certain cases, comparisons to be made between contamination levels in different areas. The advantage of this method is that it’s simple and low cost, which would be impossible with conventional analyses using automatic measuring devices. Plants are particularly useful as biological indicators to evaluate air pollution because of their wide distribution and low sampling cost. Mosses and lichens have also been recognized as the most appropriate biomonitors of atmospheric heavy metals. Additionally, trees are very efficient at trapping atmospheric particles, mostly on their foliage. The concentrations of metal and metalloids in plants depend on root uptake and dry and wet depositions on outer plant organs such as foliage or bark. Therefore, the elemental analysis of plant samples has, for many years, been an alternative, easy, and effective way of conducting ecological investigations in urban areas. The method of assessing air pollution by using bioindicators is not only in constant and widespread use, but it is also continuously being developed.

This Special Issue of the journal "Atmosphere" focuses on the current state of knowledge of air pollution in anthropized and natural areas, to determine the concentrations of the main pollutants, model their spatial distributions and identify their sources, measuring their concentrations through the use of bioindicators.

New research papers, reviews, case report, and conference papers are welcome to this Special Issue.

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. Atmosphere 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 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.
