Special Issue Information

The high level of ozone and fine particulate matter adversely impact human health in most urban areas. A number of organic and inorganic chemical species are involved in generating ozone and fine particulates in the atmosphere through chemical reactions, which are inherently non-linear and complex. Both theoretical and experimental studies are required to understand this complex chemical reaction system. Especially, much needed are detailed measurement and monitoring of chemical speciation of PM2.5 and VOCs. For the past twenty years, both intensive monitoring and long-term monitoring have been conducted to identify major chemical species contributing to the formation of ozone and fine particulate matters. Recent advances in instrumental methods have revolutionized speciation measurement in terms of accuracies, temporal, and spatial resolutions.

In this Special Issue, we encourage the publication of papers on three topical areas: development and application of real-time monitoring methodology, intensive speciation measurements, long-term speciation monitoring. The first topic deals with measurements of PM2.5 composition and VOC speciation using state-of-art real-time monitoring equipment including on-line GC, on-line IC, on-line XRF, aerosol mass spectrometer, PTR mass spectrometer, and chemical ionization mass spectrometer. The second topic deals with collaborative studies involving several research groups on intensive monitoring of the specific air pollution episode. Finally, the third topic deals with the analysis of long-term monitoring data from local or regional monitoring networks including PM speciation monitoring networks, VOC speciation monitoring network, acid deposition monitoring network, and hazardous air pollutant monitoring network.

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.

The indoor air quality of healthcare and care facilities is poorly studied. The aim of this study was to qualitatively and quantitatively describe the chemical pollution and the microbiological contaminations of the indoor environment of these facilities. Methods: A wide range of chemical compounds (39 volatile and 13 semi-volatile organic compounds, carbon dioxide, fine particulate matter) and microorganisms (fungi and bacteria) were studied. Sampling campaigns were conducted in two French cities in summer 2018 and winter 2019 in six private healthcare facilities (general practitioner’s offices, dental offices, pharmacies) and four care facilities (nursing homes). Results: The highest median concentrations of chemical compounds (μg/m3) were measured for alcohols (ethanol: 378.9 and isopropanol: 23.6), ketones (acetone: 18.8), aldehydes (formaldehyde: 11.4 and acetaldehyde: 6.5) and terpenes (limonene: 4.3). The median concentration of PM2.5 was 9.0 µg/m3. The main bacteria of these indoor environments were Staphylococcus, Micrococcus and Bacillus genera, with median bacterial concentrations in the indoor air of 14 cfu/m3. The two major fungal genera were Cladosporium and Penicillium, with median fungal concentrations of 7 cfu/m3. Conclusions: Indoor air in healthcare and care facilities contains a complex mixture of many pollutants found in higher concentrations compared to the indoor air in French hospitals in a previous study.
