Title Evaluation of methods for estimating formaldehyde released from resin-containing paper and wood product dusts
Bibliographic information Oct. 1992, Vol.53, No.10, p.632-638. Illus. 18 ref.
Abstract Epidemiology studies have suggested that exposures to formaldehyde in combination with dust particles in workplace atmospheres may be linked to increased risk of some cancers. The relationship between quantities of released formaldehyde and particle soaking conditions was assessed. The chromotropic acid, MBTH, and acetylacetone analysis procedures were examined for their appropriateness in measuring released formaldehyde. Use of the chromotropic acid procedure for this purpose indicated formaldehyde levels for wood product dusts that were approximately 10 to 14 times higher than those determined by the MBTH and acetylacetone methods. The findings indicated that soaking dust particles in deionised water at 35°C for 6h, filtering to remove the particles, and measuring the released formaldehyde in the water by a colorimetric procedure that used acetylacetone reagent would provide reliable estimates of releasable formaldehyde.
