The concentrations of polychlorinated dibenzo-p-dioxins and furans (PCDD/Fs), polychlorinated biphenyls (PCBs) and polychlorinated naphthalenes (PCNs) were determined in air samples collected at four sampling sites located in two zones of Barcelona (Spain): near a municipal solid waste incinerator (MSWI) and a combined cycle power plant (3 sites), and at a background/control site. Samples were collected using high-volume active samplers. Moreover, 4 PUF passive samplers were deployed at the same sampling points during three months. For PCDD/Fs, total WHO-TEQ values were 27.3 and 10.9 fg WHO-TEQm(-3) at the urban/industrial and the background sites, respectively. The sum of 7 PCB congeners and the Sigma PCN levels were also higher at the industrial site than at the background site. In order to compare active and passive sampling, the accumulated amounts of PCDD/Fs, PCBs and PCNs in the four passive air samplers, as well as the total toxic equivalents in each sampling site were also determined. To assess the use of PUF passive samplers as a complementary tool for PCDD/F, PCB and PCN monitoring, sampling rates were calculated in accordance with the theory of passive air samplers. PUF disks allowed establishing differences among zones for the POP levels, showing that they can be a suitable method to determine POP concentrations in air in areas with various potential emission sources. Although both particle and gas phase were sorbed by the PUFs, data of gas phase congeners are more reproducible.
在西班牙巴塞罗那两个区域的四个采样点采集的空气样本中，测定了多氯二苯并对二恶英和呋喃（PCDD/Fs）、多氯联苯（PCBs）和多氯萘（PCNs）的浓度：靠近一座城市固体废物焚烧炉（MSWI）和一座联合循环发电厂（3个采样点），以及一个背景/对照采样点。使用大容量主动采样器采集样本。此外，在三个月内于相同采样点部署了4个PUF被动采样器。对于PCDD/Fs，在城市/工业采样点和背景采样点，WHO总毒性当量值分别为27.3和10.9 fg WHO-TEQ m(-3)。工业采样点7种PCB同系物的总和以及PCN总量也高于背景采样点。为了比较主动采样和被动采样，还测定了4个被动空气采样器中PCDD/Fs、PCBs和PCNs的累积量，以及每个采样点的总毒性当量。为评估PUF被动采样器作为PCDD/F、PCB和PCN监测补充工具的用途，根据被动空气采样器理论计算了采样率。PUF圆盘能够确定不同区域间持久性有机污染物水平的差异，表明它们可能是测定具有各种潜在排放源区域空气中持久性有机污染物浓度的合适方法。尽管颗粒相和气态相都被PUF吸附，但气态相同系物的数据更具可重复性。
