Structure

Source: Wood-based panels (particleboard, MDF, plywood)
Factor: Formaldehyde (CH₂O)
Study design: narrative review of production, emissions and regulation (class 5)
Effect: limit 0.025
Jurisdiction: China (ENF)
Flags: primary-missing
Caveat: the strictest Chinese class for wood-based panels; the standard itself is not in the library
