Summary: Emission testing of VOCs is commonly based on emission test chamber measurements, and to ensure comparability, the measurement performance of different testing laboratories must be verified. BAM organizes an international proficiency test every two years to ensure the homogeneity, reproducibility, and stability of the test materials. The relative standard deviations of BAM round robin tests have decreased over the years, showing improved comparability in emission chamber testing with the mean RSD decreasing to 28% in 2018.

Summary: A study conducted in 8 urban residences in Beijing measured the indoor and outdoor concentrations of 43 VOCs, identifying 36 species with significant indoor sources. A model was developed to estimate the indoor emission strengths of these VOCs, ranking D-limonene, alpha-pinene, and styrene as the top contributors. Factors such as air exchange rate, indoor temperature, and humidity were found to have significant impacts on VOC emission strengths.

Summary: This study aimed to investigate the parameters of electrically powered radiant floor heating system connected to VOC emissions, proposing a new emission model and finding relatively inefficient ways to reduce VOC concentration in the air. New research directions were also mapped out based on the results, suggesting that not all VOC contaminants are ventilated easily and there may be a need to determine their weights based on various factors.

Summary: Understanding the coupling mechanism between multi-material pollution sources and sinks is crucial for predicting pollution load. Indoor fabric materials adsorb volatile organic compounds (VOCs) due to their high loading rates and large specific surface areas, which leads to secondary source effects and prolongs indoor air pollution. Current research on VOC mass-transfer properties of building materials cannot be directly applied to fabrics because of their multifaceted anisotropic fiber-interlaced structure. This study characterized the triple porous structure of fabrics, analyzed the mass-transfer network, and proposed a theoretical prediction model of the VOC diffusion coefficient using a multistage fractal-like tree network model. The experimental and theoretical results showed that the proposed model accurately predicts the diffusion coefficient of fabrics. This research provides insight into the dynamic source and sink characteristics of fabrics in indoor environments.

Summary: This study introduces a novel composite material mixing waterborne epoxy resin and superfine ordinary Portland cement-sulphoaluminate cement for long-term waterproofing and plugging of existing underground structures. The experimental results demonstrate that the polymer-modified composite material shows better impermeability and tensile strength, with an increase in performance when an appropriate amount of waterborne epoxy resin is mixed.

Summary: This study compared the removal performance of four volatile organic compounds (VOCs) with different hydrophobicity and molecular structure in different bioreactor configurations, and found that different reactor configurations had an impact on the removal efficiency and stability of different VOCs. Microbial community analysis showed that VOCs as the sole carbon and energy source did not promote the growth of dominant bacterial members, and the populations evolved independently in each reactor configuration and operation mode.

Summary: Indoor air pollution caused by incense products can have severe health effects, especially due to the emissions of volatile organic compounds. Cone type incense products were found to be more pollutant than stick type, with some specific VOCs exceeding WHO guideline values. While there are no established limit values for indoor air for all compounds studied, acetaldehyde, acrolein, furfural, and furan are identified as compounds that deserve attention.

Summary: This study investigates the fate of volatile organic compounds in indoor environments, with a focus on the behavior of terpenes. By studying the absorption characteristics of limonene on different surfaces, it was found that limonene exhibits varying affinities to indoor materials, providing important insights into the loss of terpenes indoors.

Summary: The ISO 16000-6 standard provides guidelines for adapting the analysis of volatile organic compounds (VOCs) to very volatile organic compounds (VVOCs) in indoor and test chamber air. The same techniques of sorbent-based active sampling, thermal desorption, and gas chromatography coupled with mass spectrometry (TD-GC/MS) should be used. This study addresses the need for gaseous standards, an adapted GC column, and reliable sampling adsorbents by successfully generating a stable standard gas mixture containing VVOCs and VOCs, and determining the suitability of different chromatography columns and adsorbent combinations for VVOC analysis.

Summary: Surfactant-extracted porous silica nano particles with wrinkled structures were modified with three different organosilanes, which significantly enhanced their adsorption performance for hazardous indoor air chemicals. The dispersion forces between the adsorbates and the adsorbents played a crucial role in determining the absorption capacity of the surface-modified silica nanoparticles.

Summary: The study found that noncombustible air fresheners may cause indoor air pollution and associated health risks, mainly influenced by volatile organic compounds, carbonyls, and fine particles. In worst-case usage scenarios, chronic exposure may exceed health reference standards. Reduction in emissions from high-emissivity products is necessary to decrease exposure levels.

Summary: The study analyzed changes in red blood cells infected with P. falciparum using Raman and EPR spectroscopy, revealing alterations caused by parasite invasion including heme degradation and breakdown products of hemoglobin. Complex changes in erythrocyte membrane as a result of P. falciparum activity were also observed, along with the presence of characteristic phospholipids and amino acids indicating a protein family unique to P. falciparum. Iron ions, copper ions, and peroxyl radicals were identified in the process of iron transfer in the blood.
