Formaldehyde Emissions from Combustion Sources and Solid Formaldehyde Resin Containing Products: Potential Impact on Indoor Formaldehyde Concentrations and Possible Corrective Measures

摘要

The formaldehyde (CH sub 2 O) emission rates of combustion sources and solid CH sub 2 O resin-containing products commonly found in domestic environments are surveyed. The potential contribution of these sources to indoor CH sub 2 O concentrations are estimated using simple steady-state, indoor pollutant concentration models. The strongest contributors to indoor CH sub 2 O are pressed-wood products and foam insulation containing urea formaldehyde resins. Combustion sources and phenon-formaldehyde resin-bonded products are generally weak emitters. Potential corrective measures to reduce indoor CH sub 2 O concentrations are reviewed. Ammonia fumigation, permeation barriers on non-decorative surfaces, and increased ventilation may be useful techniques to reduce the contribution of strong solid emission sources until the CH sub 2 O emissions are reduced to more acceptable levels through normal product aging. 38 references, 1 figure, 11 tables.
