Special Issue Information

Dear colleagues,

Exposure to environmental microorganisms and microbial contaminants, such as bacteria, viruses, fungi, and their toxic by-products, such as endotoxin, mycotoxins, and other metabolites may cause various infections, respiratory diseases, inflammations, allergic responses, and cancers. Human exposure to these microbial contaminants occurs through various exposure routes, such as inhalation, ingestion, or dermal uptake. Our understanding of the links between human and animal health and environmental microbes is still at the early stage. Recent metagenomic studies have shown that the environmental microbial diversity is far more complex than we previously thought. We need more information from multiple disciplines to advance our understanding of how microbial communities are influenced by our microenvironment, such as our buildings and workplaces as well as by the changing global climate. At the same time we need more research efforts to better understand how the environment and biodiversity determine and influence human health through environmental microbiota. To address all these research gaps, we need more sophisticated tools that can quantify microbial exposures more accurately, identify environmental microorganisms leading to information on microbial community composition, and yield quantitative data on microbial abundance in the community.

This Special Issue seeks research papers on various aspects of microbial exposure through air, water, and soil in buildings and various work environments and the links between microbial exposure levels, microbial diversity, human health, and the health of workers. We especially encourage the submission of interdisciplinary work and multi-country collaborative research. We also encourage the submission of manuscripts related to new tools, such as sensors and newly-designed air samplers for assessing human exposure to environmental microbial contaminants.

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. International Journal of Environmental Research and Public Health is an international peer-reviewed open access semimonthly 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 1800 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.

Filtering nonwovens that constitute the base material for filtering facepiece respirators (FFRs) used for the protection of the respiratory system against bioaerosols may, in favourable conditions, promote the development of harmful microorganisms. There are no studies looking at the impact that different types of filtering nonwovens have on microorganism survival, which is an important issue for FFR producers and users. Five commercial filtering nonwovens manufactured using diverse textile technologies (i.e., needle-punching, melt-blown, spun-bonding) with different structural parameters and raw material compositions were used within our research. The survival of microorganisms on filtering nonwovens was determined for E. coli, S. aureus, B. subtilis bacteria; C. albicans yeast and A. niger mould. Samples of nonwovens were collected immediately after inoculum application (at 0 h) and after 4, 8, 24, 48, 72, and 96 h of incubation. The tests were carried out in accordance with the AATCC 100-1998 method. Survival depended strongly on microorganism species. E. coli and S. aureus bacteria grew the most on all nonwovens tested. The structural parameters of the nonwovens tested (mass per unit area and thickness) and contact angle did not significantly affect microorganism survival. Full article

In recent years, the algae-bacteria symbiotic system has played a significant role in the sustainable development of wastewater treatment. With the continuous expansion of research outputs, publications related to wastewater treatment via algal-bacterial consortia appear to be on the rise. Based on SCI-EXPANDED database, this study investigated the research activities and tendencies of algae-bacteria symbiotic wastewater treatment technology by bibliometric method from 1998 to 2017. The results indicated that environmental sciences and ecology was the most productive subject categories, followed by engineering. Bioresource Technology was the most prominent journal in this field with considerable academic influence. China (146), USA (139) and Spain (76) had the largest amount of publications. Among them, USA was in a leading position in international cooperation, with the highest h-index (67) in 79 countries/territories. The cooperation between China and USA was the closest. The cooperative publishing rate of the Chinese Academy of Sciences was 83.33%, but most of them were in cooperation with domestic institutions, while international cooperation was relatively limited. Methane production, biofuel production, and extracellular polymeric substance were future focal frontiers of research, and this field had gradually become a multi-perspective and inter-disciplinary approach combining biological, environmental and energy technologies.
