Gaseous emissions of combusted electronic scrap, PVC, carpet and wood were monitored for polycyclic aromatic hydrocarbons (PAHs) by simultaneous use of semipermeable membrane devices (SPMDs) and shoots of spruce needles (Picea abies). It was found that phenanthrene, acenaphthylene and fluorene were the dominating PAHs in all samples. SPMDs and needles mainly sequestered PAH associated with the vapor phase. Particle-bound PAHs were only detected in small amounts, at which the needles tended to uptake more of these compounds in comparison to the SPMDs. Nevertheless, the logarithm of the concentrations of PAHs analyzed in both passive samplers after the same sampling period exhibited a significant linear correlation with correlation coefficients larger than 0.8073. SPMDs and spruce needles can complement each other in passive air sampling for compounds with a preference to the gas phase rather than aerosols.
通过同时使用半透膜装置（SPMD）和云杉嫩枝（欧洲云杉），对燃烧后的电子垃圾、聚氯乙烯、地毯和木材的气体排放中的多环芳烃（PAH）进行了监测。结果发现，菲、苊烯和芴是所有样品中的主要多环芳烃。SPMD和嫩枝主要截留与气相相关的多环芳烃。仅检测到少量与颗粒结合的多环芳烃，与SPMD相比，嫩枝倾向于吸收更多此类化合物。然而，在相同采样期后，两个被动采样器中分析的多环芳烃浓度的对数呈现出显著的线性相关性，相关系数大于0.8073。对于偏好气相而非气溶胶的化合物，SPMD和云杉嫩枝在被动空气采样中可以相互补充。
