“…Consequently, it has become virtually impossible to eliminate harmful substances before occupants move into their apartments [8]. As a result, the indoor air quality in these residential buildings is progressively deteriorating over time [9]. Furthermore, due to the emphasis on energy conservation, reinforced insulation and high levels of airtightness are being implemented, which limits the amount of indoor ventilation available to residents [10].…”

This study investigates the effectiveness of different ventilation methods in reducing indoor air pollutants in newly constructed residential buildings, focusing on indoor air quality (IAQ) in Dubai. The paper highlights the growing concern for IAQ in response to residents’ increasing awareness of their well-being and environmental sustainability. The study examines the concentrations of formaldehyde (HCHO), volatile organic compounds (VOCs), and total volatile organic compounds (TVOC) in bedrooms and living rooms before and after implementing various ventilation methods during the construction phase. The findings indicate that mechanical exhaust ventilation, mainly through bathroom and kitchen exhaust fans, was highly effective in reducing HCHO levels. Combining kitchen and bathroom exhaust fans demonstrated the most significant reduction in HCHO concentrations. Similarly, reductions in VOCs, such as ethylbenzene, toluene, and xylene, were observed with different ventilation methods. Natural ventilation also proved effective in reducing pollutant concentrations. The results emphasize the importance of implementing appropriate ventilation strategies to improve IAQ in residential buildings. However, the study acknowledges the limitations of a single-location measurement and recommends further research to validate the findings across different building types and locations. Additionally, long-term studies are necessary to assess the sustained effects of ventilation methods on IAQ. The study highlights the significance of addressing IAQ concerns in residential buildings and suggests potential research directions to explore other ventilation strategies and their energy efficiency implications. Ultimately, this research contributes to developing healthier and sustainable living environments by promoting effective ventilation strategies to mitigate indoor air pollutants.

“…Moreover, due to the harsh natural environment, SBS is increasing faster than in any other country (Araki et al, 2020). As the demands for a high living standard increase, various interior finishing materials have been developed and installed (Lee et al, 2013).…”

Furniture emits various VOCs (Volatile Organic Compounds) and formaldehyde (HCHO) into the indoor air. These indoor air pollutants can cause SBS (Sick Building Syndrome), such as sickness, headache, dizziness, nausea, drowsiness, and loss of concentration. This paper aims to provide essential data for improving indoor air quality by identifying the characteristics of the emission of VOCs and HCHO according to the characteristics of raw materials and finishing methods for furniture materials. As a methodology, a small chamber experiment was conducted with eight different test pieces with different base materials compositions and surface finishing methods. VOCs and HCHO were collected and analyzed by GC/MS (Gas Chromatography/Mass Spectrometry) and HPLC (High-Performance Liquid Chromatography). The result showed that the TVOC in the composite material differed according to the retention period of the raw material. HCHO preferentially affects the processing method and the storage period after molding rather than the retention period of raw materials. TVOC emission was lower when the surface finishing method was applied, like paint finish. HCHO emission was getting lower when the adhesive was used during molding. Furniture applied to new houses is installed indoors in the form of finished products (composite materials). It was confirmed that the emission amount from furniture was generally higher than that of the general interior finishing material. Not only using eco-friendly raw materials, securing a specific retention period for raw materials, selecting eco-friendly processing methods, securing a particular retention period after molding, and post-construction management (ventilation and bake-out) should be done through a comprehensive evaluation of furniture.

“…The VOCs considered as the leading causes of SBS are formaldehyde, acetaldehyde, benzene, ethylbenzene, limonene, p-dichlorobenzene, styrene toluene, xylene, and acetone. These are mainly generated from building materials, paint, ink for printing, or smoke from cooking [ 10 ]. Since it is difficult to be completely free from VOCs in our daily life and in industry, we aimed at the detection and adsorption of VOCs.…”

The detection and removal of volatile organic compounds (VOCs) are emerging as an important problem in modern society. In this study, we attempted to develop a new material capable of detecting or adsorbing VOCs by introducing a new functional group and immobilizing metal ions into a microfiber nonwoven fabric (MNWF) made through radiation-induced graft polymerization. The suitable metal complex was selected according to the data in “Cambridge Crystallographic Data Center (CCDC)”. 4-picolylamine (4-AMP), designated as a ligand through the metal complex data of CCDC, was introduced at an average mole conversion rate of 63%, and copper ions were immobilized at 0.51 mmol/g to the maximum. It was confirmed that degree of grafting (dg) 170% 4-AMP-Cu MNWF, where copper ions are immobilized, can adsorb up to 50% of acetone gas at about 50 ppm, 0.04 mmol/g- 4-AMP-Cu-MNWF, at room temperature and at a ratio of copper ion to adsorbed acetone of 1:10.
