Title

DEVELOPMENT OF A THERMAL DESORPTION METHOD FOR THE ANALYSIS OF PARTICLE ASSOCIATED POLYCYCLIC AROMATIC HYDROCARBONS IN AMBIENT AIR

Pages

  165-170

Abstract

 An investigation for the analysis of POLYCYCLIC AROMATIC HYDROCARBONS in airborne particulates using THERMAL DESORPTION and GAS CHROMATOGRAPHY-mass spectrometry is described. Samples are obtained from AMBIENT AIR using fibreglass filters and the volatile material from the filter is thermally desorbed to gas chromatograph. A 30 meter capillary column is used to separate the hydrocarbons and eight polyaromatic hydrocarbons are used to test the method and recovery is >95%. The eight POLYCYCLIC AROMATIC HYDROCARBONS anthracene, phenanthrene, fluoranthrene, pyrene, benzo (a) anthracene, chrysene, benzo (a) pyrene and benzo (e) pyrene were the most abundant PAHs found in the samples of AMBIENT AIR with current method at Uxbridge-London. Application of the measurement of POLYCYCLIC AROMATIC HYDROCARBONS in AMBIENT AIR samples shows that the hydrocarbons trapped in the particle phase to a lesser degree at higher ambient temperature. In conclusion a method has been developed to transfer the PAHs in particle phase from a filter to GC-MS by THERMAL DESORPTION. A standard mixture of PAHs, when absorbed onto the filter, did lead to strong analyte absorbent interactions by the high percent recovery of the sample.
