| Popis | A field study was performed to derive uptake rates of airborne polybrominated diphenyl ethers (PBDEs) to polyurethane foam (PUF) disk passive air samplers (PAS) and to investigate the influence of deployment location and device design. Data are presented on the gas-particle partitioning of PBDEs, since atmospheric phase distribution was considered to be a variable which could affect sampler performance. Uptake rates for these compounds were similar to those derived previously for other classes of persistent organic pollutants (POPs). Whilst other compound classes (e.g. polychlorinated biphenyls) are predominantly present in the air in the gas phase, PBDEs have a significant association with particulates in the atmosphere at ambient temperatures. The PUF disk PAS is therefore sampling PBDEs present on fine aerosols with a similar sampling efficiency to gas phase compounds. A comparison of the most commonly used PUF deployment configurations, used by different research groups, indicated little difference in uptake rates. |
