| Abstract: | A sampling system and analytical procedure for determining PCDD/Fs, PCBs, HCB, and PAHs in ambient air was tested. The reproducibility of the concentrations and the gas/particle partitioning was ± 10% for most compounds. The removal of gaseous compounds on the XAD resin trap was greater than 99%. The adsorption of gaseous substances on the glass fiber filter was negligible for compounds primarily found in the gas phase, but could not be ruled out for compounds found mainly on particles. |
