文摘
- •
Excellent detectability and repeatability at short exposure time in a low concentration environment.
- •
Very sensitive analytical protocol based on TD-GC-MS.
- •
Sampling rates for OPAHs and PAHs of 0.046 ± 0.03 and 0.12 ± 0.07 m3/day, respectively.
- •
No apparent difference in sampling rates for particle-associated and gaseous compounds.
- •
Gravitational settling is the dominant uptake mechanism for particles carrying PAHs and OPAHs.
