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

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 impact of these sources on indoor CH sub 2 O concentrations are estimated using simple steady-state, indoor pollutant concentration models. Source emission rates, product loadings for solid emission sources, duty cycles for combustion sources, and potential permeation barriers are considered in the model. The strongest contributors to indoor CH sub 2 O are pressed-wood products and foam insulation containing urea formaldehyde resins. Combustion sources and phenol-formaldehyde resin-bonded products are generally weak emitters. 26 references, 1 figure, 9 tables. (ERA citation 09:029200)
