Special Issue Information

Dear Colleagues,

Considering the current context of the COVID-19 pandemic, indoor air quality has become an increasingly important issue. Time spent indoors has increased due to lockdowns and remote working. In this new reality most of our exposure to particulate matter takes place indoors, where levels can far exceed those measured outdoors. Studies focusing on the detailed physicochemical characterization of particulate matter in indoor environments are of great interest due to their ability to trigger toxicological responses with impact on human health. The toxicological properties of the particulate matter to which we are exposed influence the cytotoxicity, genotoxicity, mutagenicity and potential to induce inflammation, constituting an issue of great concern in the scientific community.

Guest Editors invite you to consider submitting your research for publication in this Special Issue of Atmosphere focusing on “Chemical Composition and Toxicology of Indoor Particulate Matter”. The aim of this Special Issue is to communicate a selection of novel contributions in the form of critical reviews and research papers related to indoor air pollutants/quality and their toxicological effects. Potential authors are welcome to contact the Guest Editors with questions regarding their chosen topics for 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.

Standard Reference Material® (SRM®) 2585 can be considered as a model sample of settled indoor dust. At least 168 adsorbed chemicals were identified and quantified, generating a complex and potentially toxic mixture. Inhalable fractions PM10 and PM2.5 were isolated and compared to SRM® 2585 for their intrinsic properties and their respiratory toxicity using pertinent normal human bronchoepithelial (NHBE) cells. The intrinsic oxidative potential (OP) of SRM® 2585 and its subfractions was measured in acellular conditions, together with ROS generation and endotoxin content. For SRM® 2585 and PM10, cellular responses were evaluated on NHBE cells after 72 h exposure (1.1 to 110 µg/mL). The presence of endotoxins associated with an intrinsic prooxidant potential did not lead to the induction of an inflammatory response. Interestingly, cytokine production was decreased, strongly for IL-1β and to a lesser extent for IL-6. Only PM10 induced an acute toxicity. In parallel, mutagenicity was evaluated from organic extracts. Mutagenic profiles indicated the concomitant presence of nitro-PAHs in addition to the previously reported PAHs. This could be of concern for long-term health effects in a context of chronic exposure. Full article
