Special Issue Information

Dear Colleagues,

VOCs are an important group of chemicals that have attracted a great deal of attention in recent years. It 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 inform 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 under the action of nitrogen oxides and ultraviolet radiation. Some VOCs are also involved in the greenhouse effect. Therefore, VOCs should be given much attention and concern.

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 come not only from urban but also from suburban and rural areas.

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

  • Advanced sampling equipment and methods
  • Analytical methods
  • Sensors and detector
  • Suitability of absorbent materials
  • VOC and odor emissions
  • VOC exposure
  • Atmospheric environment
  • Indoor air quality
  • Health risks assessment
  • 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.

People today spend most of their time indoors; many use fragrances in closed restrooms and bathrooms at home and in public spaces for masking odors. However, volatile organic compounds (VOCs) that are emitted from indoor fragrances have been reported in recent years to pose a risk to health. In this work, microneedle trap samplers (NTSs) were fabricated, packed with sulfonated divinylbenzene (SDVB) adsorbents, and used in passive mode to extract the VOCs that were emitted by bamboo diffusers in fragrance bottles in bathrooms. Instrumental analysis revealed that the main VOCs that were emitted from chemically synthesized fragrances were ethanol (19.2–40.5 ppb), propylene glycol (273.4–527.9 ppb), and 3-ethylbenzaldehyde (3.8–12.4 ppb). Lower indoor air change rates were associated with significantly higher emitted concentrations of VOCs. 3-Ethylbenzaldehyde is a strong respiratory irritant, and outdoor pollutants such as toluene, which escapes from paints, have a negative impact on indoor air quality.
