| Abstract: |
In order to
employ PUF disk passive air sampler (140 mm
diameter, 12 mm thickness) as a quantitative
sampling device a set of calibration experiments
were carried out. Time integrated indoor air
concentrations of PCBs and PBDEs were obtained
from a low volume air sampler. The low volume
active sampler was run alongside the passive
samplers throughout the calibration period in an
office microenvironment. Sampling rates of
routinely employed passive sampler design were
determined for 51 PCB and 6 PBDE congeners
detected in all calibration samples. PUF disk
R-values varied from 0.63 to 1.54 m3 day-1 for
individual PCBs and from 1.1 to 1.9 m3 day-1 for
PBDE congeners. The theory of passive sampling
is also discussed and mass transfer coefficients
(kA) of PCB and PBDE congeners
provided. |
