The results of a 12-month study of more than 100 solvent extractable organic compounds (SEOC) in particulate matter (PM) less than or equal to 2.5 μm (PM 2.5 ) collected at three air monitoring stations located at roadside, urban, and rural sites in Hong Kong are reported. The total yield of SEOC that accounts for ∼8-18% of organic carbon (OC) determined by a thermal optical transmittance method was 125-2060 ng/m 3 , which included 14.6-128 ng/m 3 resolved aliphatic hydrocarbons, 39.4-1380 ng/m 3 unresolved complex mixtures, 0.6-17.2 ng/m 3 polycyclic aromatic hydrocarbons, 41.6-520 ng/m 3 fatty acids, and
