Abstract
When used indoors, wood-based panels release volatile organic compounds (VOCs) such as olefins, aromatics, and esters, posing risks to human health. VOCs are key pollutants affecting indoor air quality and are closely linked to human health and quality of life. VOC emissions from wood-based panels primarily originate from adhesives, chemical formulations, and wood components, and their release characteristics are influenced by material properties and processing conditions. Gas chromatography-mass spectrometry is commonly used to determine total volatile organic compound (TVOC) content. Effective control strategies include the degradation and mineralization of wood extracts, the use of water-based additives and adhesives, and the modification or substitution of coatings and adhesive systems. This paper systematically reviews the sources and volatilization characteristics of VOCs in wood-based panels, as well as current technologies for reducing VOC emissions. The aim is to identify suitable testing methods and emission control approaches to improve indoor air quality and provide a safer and healthier indoor environment for users.
