Title: A brief review of control measures for indoor formaldehyde

Indoor environments contain a variety of consumer and construction products that emit formaldehyde (CH/sub 2/O) vapor. The strongest CH/sub 2/O emitters are typically particleboard underlayment and industrial particleboard, hardwood plywood paneling, urea-formaldehyde foam insulation, and medium density fiberboard, all of which contain urea-formaldehyde (UF) resins. The contribution of individual products to indoor CH/sub 2/O levels depends on several parameters, including the quantity and age of the product, building ventilation rate, presence of permeation barriers, temperature (T), relative humidity (RH), and CH/sub 2/O vapor concentration resulting from all of the CH/sub 2/O emitters (1,3-8). Combustion sources (e.g., kerosene heaters, gas stoves and cigarettes), carpet and carpet padding, resilient flooring (e.g., linoleum), gypsum board, non-apparel and apparel textiles, ceiling tiles, fibrous glass insulation and softwood plywood subflooring are generally weak emitters that do not contribute significantly to steady-state, indoor CH/sub 2/O levels. Control measures exist to reduce CH/sub 2/O emissions from consumer and construction products during their manufacturer and in post-installation applications. This note summarized the effectiveness of the following subset of post-installation control measures: product aging, installations of permeation barriers (i.e., flooring) and increased building ventilation. 14 refs.
