“…The summer/winter ratios for total PAHs (APAH) and each individual congener are listed in the last column of Table 1. As can be seen, except for Flt and I(cd)P, they ranged from 1 to 2; the sole value below unity was that for anthracene, which is consistent with previous results of Escrivá et al, 1991 for Valencia and reflects a distinct behaviour in this PAH. As can also be seen, the W/S ratio for APAH was 1.37 and hence much lower than those found by Papageorgopoulou et al (1999) in the Greek cities of Moudania and Kilkis (12 and 12, respectively), but similar to that found in Edessa, a city that bore heavy vehicular traffic in the sampled zone during the summer.…”

Concentration levels, seasonal variation and winter/summer ratios of 11 polycyclic aromatic hydrocarbons (PAHs) in the TSP of Las Palmas de Gran Canaria city were determined. The study area is under the influence of heavy traffic (80000 vehicles/day). Pyr/BaA, Pyr/Flt, B(ghi)P/I(cd)P and B(b+k)F/B(ghi)P ratios were calculated; the values of these two last suggest a strong influence of diesel fuel burning. Levels of TSP and TSP-bound PAHs were also established. The hazard potential of PAHs in terms of carcinogenicity of BaP is acceptable. Potential risk on the basis of TEFs is also studied.

Size fractionated mainstream cigarette smoke (MCS) samples were collected with variable configuration cascade impactor (VCCI). Samples were extracted ultrasonically and analysis of sixteen priority polycyclic aromatic hydrocarbons (PAHs) was performed using high performance liquid chromatography (HPLC) coupled with UV-visible detector. Identification of PAHs were also carried out using gas chromatography coupled with mass spectrometry (GC-MS) technique. Data of size fractionate PAHs in MCS were used to calculate size dependent deposition in different compartment of human respiratory tract using multiple path particle dosimetry (MPPD) model. All brand cigarette smoke showed similar trends of particle mass and PAHs size distribution peaked at two sizes 0.3-0.1 µm and 0.75-1.13 µm aerodynamic diameter. All tested brands of MCS recorded around 48.75% of two and three-ring PAHs, 23 to 25% fourring PAHs and 26-27% five and higher rings PAHs of total analyzed PAHs. Benzo[a]pyrene equivalent (B[a]P eq ) PAHs emission in MCS was found to be 110 ± 12 (µ ± 1σ) ng per cigarette for tested brands. Total deposition fraction in respiratory tract was found to be 0.69 ± 0.26 for tested size ranges. Average 5 th and 95 th percentile values of incremental lifetime cancer risk (ILCR) for smoker due to PAHs exposure were found to be 1.3 × 10 -5 to 3.9 × 10 -5 respectively for tested cigarette brands.

Two-step laser mass spectrometry (LZMS) was applied to study the chemical nature of adsorbates on aerosol particles which were collected from different sites, e.g. in the countryside, in an industrial zone, by a downtown road, and in a tunnel. The method combines infrared laser desorption from the particle surfaces followed by ultraviolet laser post-ionization of the desorbed neutral molecules. Because of the high sensitivity and optical selectivity of LZMS, virtually no sample preparation is needed, and mass spectra can be recorded in a very short time. Qualitative and quantitative comparisons of plycyclic aromatic hydrocarbons in different sampling areas were carried out. By scanning the ionization laser wavelength, two-dimensional UV/MS spectra can be generated for better identification of the adsorbed species.
