• Description:
  A method for estimating formaldehyde (50000) dose from inhalable airborne dust/fibers was described. Applicability of the method to actual field conditions was noted. The method incorporated an inhalable sampler for collection of the dust/fibers. Filters containing sampled dust/fibers were placed in distilled water and incubated at 37 degrees-C for 4 hours to free the formaldehyde. Detection limits were 0.44 and 0.08 micrograms per filter sample for the chromotropic-acid and the 2,4-DNP procedures, respectively. Inhalable and closed face samplers were compared to cassette samplers at a garment factory and a waterbed accessory operation. At the garment factory, the inhalable samplers collected more dust/fibers; at the accessory facility, sampler efficiencies were comparable. The authors suggest that, although the hydrolysis procedure employed to liberate formaldehyde from dust/fibers may differ from that in the nasal and oropharyngeal passages, collection levels approximated localized inhaled dose.
