We evaluated the potential utility of couch PUF as a passive sampler and as a reservoir for non-flame retardant semivolatile organic compounds (SVOCs).<h4>Methods</h4>We collected PUF samples from 13 California home couches, measured concentrations (C_PUF) of 64 SVOCs at three different depths (i.e., top, top-middle, and middle from couch surfaces facing outward), and examined concentration changes with depth. To calculate the PUF-air partition coefficient (K_PUF-air = C_PUF/C_air = C_PUF × K_dust-air/C_dust), we used the calculated dust-air paChemosphereEvaluating couch polyurethane foam for a potential passive sampler of semivolatile organic compounds.PMC7969436P30 ES023513P42 ES004699Young TMKim KWong LShin HMBennett DHfalseEvaluating couch polyurethane foam for a potential passive sampler of semivolatile organic compounds.<h4>Background/objective</h4>Polyurethane foam (PUF), a proven sampling medium for measuring air concentrations of organic compounds, is widely used in upholstered home furniture.
