Special Issue Information

Dear Colleagues,

Biomass burning is the dominant source of carbonaceous aerosol, affecting regional air quality and global climate, and thus directly and indirectly impacting human health. Combustion of biomass takes place in one form or another in essentially every part of the globe, such as through open burning of agricultural residues, slash-and-burn practices, grassland and forest fires, as well as residential combustion of biofuels in stoves and fireplaces for cooking and heating. Thus, large amounts of aerosol particles and gaseous pollutants are emitted into the atmosphere, which can be transported thousands of kilometers away from the source areas, affecting even remote regions, while undergoing chemical and physical transformations. Consequently, physico-chemical and toxicological characteristics of biomass burning aerosols are complex and highly variable.

This Special Issue, therefore, aims to disseminate the latest research findings from either field or modeling studies, investigating the inherent properties of smoke emissions from different types of biomass burning, including wildfires, prescribed burning or domestic biofuel combustion. Authors are invited to submit manuscripts reporting results from ambient air measurements, controlled combustion experiments, as well as targeted health effects studies. Review papers are welcome as well. Ultimately, we hope to convey with this Special Issue a better understanding of the chemical, physical and toxicological properties of aerosol emissions from biomass burning processes to scientists across various disciplines.

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. Toxics 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 2600 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.

Glyoxal (CHOCHO) is a trace gas in the atmosphere, often used as an indicator of biogenic emissions. It is frequently compared to formaldehyde concentrations, which serve as indicators of anthropogenic emissions, to gain insights into the characteristics of the environmental source. This study employed broadband cavity-enhanced absorption spectroscopy to detect gaseous CHOCHO, methylglyoxal, and NO2. Two different detection methods are compared. Spectrograph and CCD Detection: This approach involves coupling the system to a spectrograph with a charge-coupled device (CCD) detector. It achieved a 1 min 1-σ detection limit of 2.5 × 108 molecules/cm3, or 10 parts per trillion (ppt). Methylglyoxal and NO2 achieved 1 min 1-σ detection limits of 34 ppt and 22 ppt, respectively. Interferometer and PMT Detection: In this method, an interferometer is used in conjunction with a photomultiplier tube (PMT) detector. It resulted in a 2 min 1-σ detection limit of 1.5 × 1010 molecules/cm3, or 600 ppt. The NO2 2 min 1-σ detection limit was determined to be 900 ppt. Concentrations of methylglyoxal were difficult to determine using this method, as they appeared to be below the detection limit of the instrument. This study discusses the advantages and limitations of each of these detection methods. Full article
