“…Low molecular weight PAHs are found predominantly in the gas phase, while those with four or more rings are found mainly in the particle phase. Van Vaeck et al [10] have found that about 80 % of the atmospheric inventory of particulate PAHs is associated with particles below 1 µm. Miguel and Friedlander [11] have reported that around 75 % of benzo[a]pyrene (B[a]P) is associated with particles smaller than 0.26 µm, that may deposit into the alveoli causing lung diseases such as asthma or emphysema, even when low concentrations are present.…”

Sugar cane burning in Brazil causes remarkable amounts of organic compounds to be emitted amongst which the polycyclic aromatic hydrocarbons (PAHs) represent serious health hazards.Therefore, twenty-four hour aerosol samples (< 10 m aerodynamic diameter) were collected in Araraquara city (São Paulo state) during the harvest season using a Hi-Vol sampler. PAHs were recovered using an Accelerated Solvent Extractor and analyzed by low pressure-gas chromatography-ion trap mass spectrometry (LP-GC-ITMS). The fully automated extraction process was performed in less than 25 min with a solvent consumption of approximately 20 mL.The use of a deactivated 0.6 m x 0.10 mm ID restrictor coupled to a 10 m wide-bore analytical column allowed most of the 16 PAHs in EPA's priority list to be identified and quantified in only 13 min. Concentrations of PAHs in Araraquara aerosols ranged between 0.5 ng m -3 and 8.6 ng m -3 .

Polycyclic aromatic hydrocarbon (PAH) samples in the ambient air of rural, urban and trafficintersection sites have been collected by PS-1 samplers, NRI (Noll Rotary Impactor) and MOUDIs (Micro-orifice Uniform Deposit Impactors) from July, 1993 to January, 1995 in southern Taiwan. Twenty one individual PAHs were analyzed primarily by a gas chromatograph/mass spectrometer (GC/MS). The mean total-PAH concentrations (gas+particle phases) in the ambient air of trafficintersection was approximately 5.6 and 14.1 times higher than those mean values for the urban and rural atmosphere, respectively. It is reveals that the high density of vehicle exhaust raises the PAH concentrations in the urban ambient air. In the ambient air of the traffic-intersection, most of the G/R (ground/roof) ratios for individual PAHs concentration in gas phase were higher than 1.0, except BaA, BeP, PER and BghiP. This result shows that PAHs concentration in gas phase was related to the automobile exhaust. Upon entering the ambient air of the traffic-intersection, these PAHs was condensed, cooled and dispersed at higher elevation. In the traffic intersection, the PAHs are predominantly absorbed on particles with aerodynamic diameters less than 2.5 µm (the fine particles), a fact which strongly relates to the risk potential. The results also show that the total PAHs in the ambient air of a traffic intersection originated mainly from mobile exhaust and the phenomena of condensation process for the young aerosols. However, in the traffic-intersection, higher fraction of total-particle mass in the coarse particle mode is primarily the road dust which is due to traveling vehicles.
