Many wooden flooring products
containing formaldehyde-based resins release formaldehyde vapors,
thus causing consumer’s dissatisfaction and health-related
complaints. Various symptoms such as the most common of which
is irritation of the eyes and the upper respiratory tract are attributed
to the emission of formaldehyde gases. Also, formaldehyde
has been found to produce nasal carcinomas in mice and rats after
a prolonged exposure at 14.1 and 5.6 mg/L level, respectively.
These findings have led to an intensified interest in the indoor
environment. Consumer products, especially construction materials,
are a major source of formaldehyde emissions in the indoor
environment (Kim et al., 2007a; Brown, 1999).
