Special Issue Information

Dear Colleagues,

People spend more than 80% of their time in indoor environments, including homes, offices, schools, and other indoor public spaces. Indoor air quality has a crucial influence on human health, comfort, productivity, and wellbeing. Due to the increasing demand for more comfortable and convenient homes and workplaces, many synthetic materials and products that contain abundant chemicals have become ubiquitous indoors. Many of these chemicals (e.g., formaldehyde, benzene series, phthalates, flame retardants) that are potentially harmful to humans are gradually released to the indoor air, which subsequently result in the deterioration of indoor air quality. Additionally, some processes that occur indoors (e.g., combustion and smoking) and infiltration of outdoor air may also introduce air pollutants to indoor environments. The observation and control of indoor air pollution have raised great attention from the public. It is important and necessary to conduct research on the characteristics and control of indoor air pollution.

This Special Issue aims to collect high-quality research articles and reviews about the characteristics and control of indoor air pollution. Topics of interest include but are not limited to:

  • The fate and transport of pollutants in indoor environments (both experimental and numerical studies are welcome);
  • Composition, concentrations, spatial and temporal distribution of pollutants in various indoor media (e.g., air, suspended particles, settled dust, and indoor surfaces);
  • The control/mitigation of indoor air pollution in combination with novel and/or existing technologies;
  • Ventilation and interaction between indoor and outdoor air pollution;
  • Policies and strategies related to the control of indoor air pollution.

Semi-volatile organic compounds (SVOCs) are important pollutants in indoor environments. Quantification of gaseous SVOC concentrations is essential to assess the pollution levels. Solid-phase microextraction (SPME) is considered to be an attractive sampling technique with merits, including simplicity of use, rapid sampling, and solvent free. However, the applications of SPME for sampling gaseous SVOCs are often limited by the fluctuating velocity of indoor air (leading to an unstable sampling rate) and the uncertainties associated with the traditional calibration of SPME. Therefore, we established an SPME-based active sampler to ensure the stable sampling of SVOCs in fluctuating air and developed a two-step calibration method based on the sampling principle of SPME. The presented method and a traditional method (sorbent tubes packed with Tenax TA) were simultaneously used to measure SVOC concentrations in an airstream generated in experiments. Three typical indoor SVOCs, diisobutyl phthalate (DiBP), tris (1-chloro-2-propyl) phosphate (TCPP), and benzyl butyl phthalate (BBzP) were chosen as the analytes. Mean concentrations measured by SPME agreed well with the sorbent tubes (relative deviations <12%), supporting the feasibility of the presented method. Further studies are expected to facilitate the application of the presented method (especially the problem associated with the sampling-tube loss of low volatile SVOCs). Full article
