Abstract
Furniture products are the main sources of indoor air pollution due to the emission of formaldehyde and volatile organic compounds (VOCs). It is great significant to establish a scientific certification and evaluation system to promote furniture manufacturers to reduce the harmful substances release in furniture products and protect human health in China. This paper describes an investigation on release of formaldehyde, soluble heavy metals, benzene, toluene, xylene and other substances from 28 furniture products by dryer method and environmental chamber method. Studies on current development status of certification and evaluation of harmful substance release from furniture products in China were carried out. Case study of certification and evaluation method suitable for furniture production industry was made, and the existing problems and suggestions were provided for improvement of certification and evaluation method system based on the characteristics of furniture industry.
Highlights

Establishing a scientific certification and evaluation system is significant to improve indoor air pollution, and to promote furniture manufacturing enterprises to reduce the release of harmful substances in furniture products and to protect human health
Voluntary product certification as a third-party evaluation method, used widely in China, promotes the furniture manufacturing enterprises to reduce the release of harmful substances in products to a certain extent
Summary
Furniture is the main source of indoor air pollution because it emits formaldehyde and volatile organic compounds (VOCs). Establishing a scientific certification and evaluation system is significant to improve indoor air pollution, and to promote furniture manufacturing enterprises to reduce the release of harmful substances in furniture products and to protect human health. Third-party organizations issue VOC release labels for furniture products that meet specific requirements to promote manufacturing enterprises to reduce VOC emission in furniture products, such as Blue Angel and GUT in Germany, Green Seal, CRI Green Label Plus, LEED in the United States, and NF Environment in France., CESAT, AFSSET, Good Environmental Choice, TCO in Sweden, Swan of Nordic Europe, Umweltzeichen of Austria, EU Flower, Milieukeur of the Netherlands and others have established a identification system for VOC emissions from furniture products. Voluntary product certification as a third-party evaluation method, used widely in China, promotes the furniture manufacturing enterprises to reduce the release of harmful substances in products to a certain extent
