Abstract

Indoor furniture continuously emits various VOCs, such as aliphatic hydrocarbons, aromatic hydrocarbons, chlorinated hydrocarbons, aldehydes-ketones, and acids-esters, which affect indoor air quality and harm human health. Furniture made of different materials contains varying types and concentrations of VOCs. Dry materials (boards, leather, etc.) and wet materials (paints, adhesives, etc.) are the primary sources of VOCs in furniture. The emission of VOCs from furniture is influenced by multiple factors: the physical and chemical properties of the furniture itself (substrates, paint films and thickness, loading rate, etc.) are the decisive factors affecting VOCs emission, while environmental factors (temperature, relative humidity, air change rate, air flow velocity, etc.) also impact VOCs emission.
