The world’s leading indoor air quality guidelines provide for the identification of certain parameters with a specific limit value based on the latest empirical measurements, however, most of them do not have legal coverage and are voluntary. This leads to unequal assessment of indoor air quality, because there is an identifiable difference between the limit values set out in the various guidelines. And these values would be related to the results obtained during the experimental activities of the application of the specific parameters and the interpretation of their effects on human health. The aim of this IAQ guideline and IAQ certification review was to develop IAQ label for Nordic countries and to find gaps the legislation established by the Latvian government. The development of indoor air quality labels provides an opportunity to maintain and promote the optimal functionality of human physiological processes and the sustainability of the building.

Comparison of the Adsorption–Desorption Kinetics of Limonene and Carvone on TiO₂ and SiO₂ Surfaces under Different Relative Humidity Conditions

Adsorption and desorption of volatile organic compounds (VOCs) on indoor material surfaces can impact VOC concentrations in indoor air. In this study, we investigate the adsorption and desorption kinetics of limonene and one of its oxidation products, carvone, at 297 ± 1 K using in situ Fourier transform infrared (FTIR) spectroscopy. In particular, the adsorption and desorption kinetics of limonene and carvone on two model indoor-relevant surfaces, TiO2 (a component of paint and self-cleaning surfaces) and SiO2 (a model for window glass), are compared at low relative humidity as well as at higher relative humidity. Carvone readily partitions to both surfaces with slower desorption kinetics compared to limonene. Under dry conditions, the desorption kinetics of limonene is about 40 times faster than that of carvone from TiO2, and the desorption kinetics of limonene and carvone from TiO2 are about two and four times slower than on SiO2, respectively. Under high relative humidity conditions, the presence of adsorbed water on both TiO2 and SiO2 surfaces generally increases the desorption kinetics of limonene yet has no effect on the desorption kinetics of carvone. The K2-SURF kinetics model has been previously applied to limonene adsorption/desorption on SiO2, and here, it is used to obtain a detailed mechanism for limonene interactions on TiO2 as a function of relative humidity to explain the observed kinetics. Importantly, the combined experimental results with kinetic modeling and classical and ab initio molecular dynamics simulations provide mechanistic insights into the heterogeneous interactions of volatile organic compounds on indoor-relevant surfaces and implications for indoor air quality.

“…Volatile organic compounds (VOCs) are organic chemicals that are emitted from natural and artificial products such as cleaning detergents, cosmetics, paints, adhesives, and cigarette smoke. , Although the concentration of VOCs is strictly regulated to a low level by global consensuses and national laws, the residual amount of VOCs in the atmosphere causes health problems. For instance, toluene vapor is emitted from paints, adhesives, and printers with an average concentration of 31.5 μg m –3 . , Acetone is found in wallpaper and furniture polish, and its typical concentration in indoor air is around 60 μg m –3 . , These VOCs are known to cause headaches, nausea, and even more severe diseases like cancers. − …”

Polymer Optical Microcavity Sensor for Volatile Organic Compounds with Distinct Selectivity toward Aromatic Hydrocarbons

et al. 2021

View full text Add to dashboard Cite

A whispering-gallery mode (WGM) optical resonance sensor for volatile organic compounds (VOCs) is developed from polystyrene (PS) microspheres doped with fluorescent βcyano-appended oligo(p-phenylenevinylene) (β-COPV). The β-COPV-doped PS microspheres (MS COPV ) are formed by the miniemulsion method in a binary solvent. MS COPV expand upon permeation of VOCs into the PS matrix and exhibit a spectral shift of the WGM resonance peak. The permeation efficiency is highly dependent on the chemical affinity between the analyte and the polymer matrix, with exceptionally high selectivity toward aromatic hydrocarbons such as benzene, toluene, and xylenes (BTXs). The high selectivity and sensitivity of MS COPV are in clear contrast to those of conventional WGM sensors that just detect VOCs nonpreferentially through adsorption onto the surface.

Comparative analysis of formaldehyde and toluene sorption on indoor floorings and consequence on Indoor Air Quality

Abstract: Indoor surfaces may be adsorptive sinks with the potential to change Indoor Air Quality. To estimate this effect, the sorption parameters of formaldehyde and toluene were assessed on five floorings by an experimental method using solid-phase microextraction in an airtight emission cell.
