Air Pollution in Chemical Industries

Dear Colleagues,

This Special Issue aims to present recent developments in air pollution from chemical plants.  Innovations should be related to the methodology used to estimate emissions, the fate and transport of these hazardous air pollutants, and multi-pathway human and ecological risk assessments.  The decarbonization of the economy has caused a massive reduction in emissions from power plants. Therefore, chemical industrial operations remain a major source of human health and ecological deterioration from air pollution.

Currently, there are several limitations to estimating impacts.  These are characterized by the collection of atmospheric pollutant concentrations on a very limited number of contaminants and at point locations without knowledge of the substances’ origins.  This is the case, for example, for chemical plants emitting over 1200 chemicals of concern. Ambient air monitoring stations measure at most 30 of these contaminants. Furthermore, studies include only the direct inhalation pathway, while ignoring the accumulation of air toxics in the food web.  Public and ecological receptors only have restricted ambient air quality standards, which are established by environmental regulatory agencies.  The only acceptable approach to assess the impacts are by the use of mathematical models for the exposure estimations, along with data on the transport and end-point toxicity.  Final health and ecological impacts must be assessed with terms of risks.

The focus of this Special Issue is, therefore, to collate original research on novel models to monitor and estimate emissions, evaluate fate and transport in multimedia to receptors (humans and ecological), and assess of toxic risks coming from chemical industries.

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 250 words) can be sent to the Editorial Office for assessment.

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.
