Special Issue Information

Dear Colleagues,

VOCs are an important group of chemicals that have attracted a great deal of attention in recent years. This group mainly consists of alkanes, alkenes, aromatic compounds, esters, aldehydes and ketones, etc. They are commonly used as solvents, plasticizers, fuel additives, etc. Moreover, VOCs are responsible for the aroma of food, can cause metabolic changes in the body, can provide signaling molecules for plants and bacteria, and play an important role in the environment.

Some VOCs are directly or indirectly toxic to human health. In addition, they are involved in the formation of photochemical smog, producing ozone, other toxic organic pollutants or secondary organic aerosols via nitrogen oxides and ultraviolet radiation. Some VOCs are also involved in the greenhouse effect. Therefore, attention should be paid to VOCs.

Some VOCs can generate unpleasant odors, which can lead to many complaints and dissatisfaction, and in severe cases, even impair human health. The sources of these odorous substances are manifold, and they are derived not only from urban but also from suburban and rural areas.

This Special Issue will summarize the latest findings regarding VOCs and odors, detection and analysis methods and effective abatement initiatives. Articles in this Special Issue can cover numerous subjects, such as indoor air, water, biological fluids (breath, blood, urine, feces, saliva, etc.), bacterial cultures, plants, food, drinks, tobacco, materials and environmental samples. The Special Issue will be focused on, but not limited to, the following topics related to VOCs:

  • Advanced sampling equipment and methods;
  • Analytical methods;
  • Sensors and detectors;
  • Suitability of absorbent materials;
  • VOC and odor emissions;
  • VOC exposure;
  • Atmospheric environment;
  • Indoor air quality;
  • Health risk assessments;
  • Effective abatement initiatives (in air, water, etc.).

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).

Because the surface of MDF is not aesthetically pleasing, it usually needs to be veneered and then painted, but such a board releases harmful VOCs, among which Benzene Series is the most harmful. Benzene and its series are a group of carcinogenic compounds. With the diluents of nitrocellulose (NC)-lacquered MDF as the research objects, the release of the Benzene Series was studied to provide a scientific basis for pollution control and a reference for eco-friendly paint production. The attenuant of NC paint, anhydrous ethanol, ethyl acetate and solvents mixed with different alcohol ester ratios were used as diluents in NC lacquer. Two kinds of wood-veneered MDF with different thickness (18 mm and 8 mm) were coated with NC lacquer and analyzed in the experiment. The gas was collected using a small environmental chamber and the Benzene Series was analyzed using GC-MS. The concentration of Benzene Series released by MDF was 316.24 μg·m−3, and that of the NC-lacquered MDF with thicknesses of 18 mm and 8 mm were 284.44 μg·m−3 and 281.06 μg·m−3, respectively. The MDF released 14 kinds of Benzene Series, and the NC-lacquered MDF with two thicknesses released 18 kinds of it. The release concentration order of Benzene Series in NC-lacquered MDF with different diluents of the 18 mm thick panel was NC-M, NC-A, and NC-E from high to low. The lowest concentration of it occurred when the ratio of anhydrous ethanol to ethyl acetate was 1:3, and the lowest amount of components were at the ratio of 1:2. The concentration of Benzene Series released by MDF is higher than that released by the NC-lacquered MDF. Thickness has no effect on the type of release. The thicker MDF was, the higher the concentration was. The alcohol and ester thinner can control the release of Benzene Series from the source, and the optimal mixing ratio was 1:3. Full article

In China, traditional food is a significant element of culture that affects human behaviors. The point of interest (POI) of traditional food restaurants’ location and their volatile organic compounds (VOCs) emissions affect the urban ecology. Rather than examine potential urban development patch (PUDP) based on land use data, the perspective of this paper is to examine the PUDP, air quality, and food culture in urban ecology in Chengdu, China. Methods: First, the research identifies three types of PUDP models (open PUDP, landscape PUDP, and conflict PUDP) with the weighted overlay of land use data, then uses machine learning to examine the relationship between PUDP, POI of traditional food restaurant, and VOCs. Results: The study generates three types of PUDP which are open PUDP, landscape PUDP, and conflict PUDP. VOCs and POI of traditional restaurant have a strong correlation, and both have a significant negative correlation with open PUDP. However, the landscape PUDP and conflict PUDP do not show an obvious relationship with food POI and VOCs. Conclusion: The results indicate that the future urban ecology should consider restaurant location, VOCs from restaurants, and their relationship to urban land use data as they have a strong relationship.
