Assessment of the impact of sampler housing on indoor passive air sampler measurements of SVOCs

Popis výsledku v původním jazyce

Passive air sampling (PAS) using a polyurethane foam (PUF) sorbent is a widely used technique to characterize air concentrations of semi-volatile organic compounds (SVOCs) in indoor environments, however, there is little consensus on the type of housing used in sampler housings and how sampler masses are converted to air concentration. We systematically evaluate the three types of PUF-PAS sampler housings most commonly used indoors, and characterize uptake rates for > 50 SVOCs, covering legacy persistent organic pollutants, pesticides, combustion by-products, and flame retardants for all three housing types. There is a clear association between the amount of shielding of the PUF disk and equivalent air volumes for PUF-PAS, with median sampling rates for double-bowl housings of 0.72 m3/day (0.62-0.92 m3/day), 1.3 m3/day (1.0-1.7 m3/day) for single bowl, and 1.8 m3/day (1.4-2.2 m3/day) for PUFs without any housing. Combining these outcomes with a meta-analysis of existing data on PUF-PAS indoor uptake, we provide recommendations for the range of applicability and selection of sampling rates for PUF-PAS in indoor environments.
