Abstract

The development of analytical procedures for the determination of PAHs in air particulates is described. The optimized methodology consisted of the following: Samples were extracted by Soxhlet for 16. hours with cylclohexane, followed by concentration of the extract under reduced pressure in a rotary evaporator. Clean-up was done by passing the extract through a Seppak silica cartridge and eluting with chloroform. Analysis was performed by HPLC with fluorescence detection. The analytes determined were anthracene, fluoranthene, benzo(a)pyrene, dibenz(a,h)anthracene, and benzo(g,h,i)perylene. Detection limits were lowest for benzo(a)pyrene with maximum value of 1 pg/m3 and highest for dibenz(a,h) anthracene with maximum value of 1 ng/m3. Sixty one (61) samples from selected Metro Manila stations were analyzed. Total PAHs ranged from 1. 74 - 10.43 ng/m3.
