“…These values are in good agreement with the ratios reported for soil and paved road dust. 47 It is also very similar to the values previously reported by Dallarosa et al 12 for two urban areas in Porto Alegre (Brazil) with heavy traffic.…”

“…5,9,11,23 Also, some results in PM 2.5 were reported. 6,12 Certainly, several studies report data for other places in the world. Nevertheless, it should be noted that concentrations of PAHs depend on several factors such as geographical and meteorological conditions, sampling, extraction and analysis procedures, sampling seasons and emission sources.…”

“…In 1996, Lopes and De Andrade 3 reviewed the sources, reactivity and analytical methods to determine PAHs and the main results obtained up to that date. Among the studies published in the last ten years, we may mention those conducted in the cities of São Paulo, [4][5][6] Rio de Janeiro, [7][8][9][10] Porto Alegre, 11,12 Campo Grande, 13,14 Niterói, [15][16][17][18][19][20] Campos dos Goytacares 21 and Salvador. 22 Most of these and other studies reported PAHs concentrations in total suspended particles (TSP).…”

. The same most abundant compounds were obtained in PM10 samples and a total mean mass of 8.99 ng m -3 was determined. Diagnostic ratios were calculated and vehicular emissions were determined as the potential sources for PAHs in particulate matter. The contribution of both light duty and diesel engines is significant, but the cluster and factorial analysis failed to classify clearly in gasoline or diesel emissions.

“…28 On the contrary, PAHs with high molecular weight (five to six rings; e.g., benzo(b)fluoranthene, benzo(a)pyrene, dibenzo(a,h)anthracene, benzo(g,h,i)perylene, and indeno(1,2,3-cd)pyrene) occurred in considerably higher concentrations at Tr, being primarily associated with PM. 33 Dibenzo(a,h)anthracene was the most abundant in traffic PM 10 and PM 2.5 , with concentrations representing approximately 30% of ⌺ PAHs in both fractions. This percentage was considerably higher than those of other PAHs, being followed by benzo(b)fluoranthene and indeno(1,2,3-cd) pyrene (ϳ10%), benzo(g,h,i)perylene (ϳ8%), and benzo(a) pyrene and chrysene (ϳ7%).…”

“…These levels were comparable with those from studies in Rome 32 or Brazil. 33 Nevertheless, in other European cities such as Copenhagen, much higher concentrations of benzo(a)pyrene (4.4 ng m Ϫ3 ) were reported. 34 Because the mean concentrations of benzo(a)pyrene at both sites were lower than the limits settled in EU legislation (1 ng m Ϫ3 ), assuming that these results could be extrapolated to the other parts of the year, it could be admitted that the limits of the EU directive will probably be fulfilled.…”

Because polycyclic aromatic hydrocarbons (PAHs) have been proven to be toxic, mutagenic, and/or carcinogenic, there is widespread interest in analyzing and evaluating exposure to PAHs in atmospheric environments influenced by different emission sources. Because traffic emissions are one of the biggest sources of fine particles, more information on carcinogenic PAHs associated with fine particles needs to be provided. Aiming to further understand the impact of traffic particulate matter (PM) on human health, this study evaluated the influence of traffic on PM 10 (PM with aerodynamic diameter Ͻ10 m) and PM 2.5 (PM with aerodynamic diameter Ͻ2.5 m), considering their concentrations and compositions in carcinogenic PAHs. Samples were collected at one site influenced by traffic emissions and at one reference site using lowvolume samplers. Analysis of PAHs was performed by microwave-assisted extraction combined with liquid chromatography (MAE-LC); 17 PAHs, including 9 carcinogenic ones, were quantified. At the site influenced by traffic emissions, PM 10 and PM 2.5 concentrations were, respectively, 380 and 390% higher than at the background site. When influenced by traffic emissions, the total concentration of nine carcinogenic compounds (naphthalene, chrysene, benzo(a)anthracene, benzo(b) fluoranthene, benzo(k)fluoranthene, benzo(a)pyrene, dibenzo(a,h)anthracene, indeno(1,2,3-cd)pyrene, and dibenzo(a,l)pyrene) was increased by 2400 and 3000% in PM 10 and PM 2.5 , respectively; these nine carcinogenic compounds represented 68 and 74% of total PAHs (⌺ PAHs ) for PM 10 and PM 2.5 , respectively. All PAHs, including the carcinogenic compounds, were mainly present in fine particles. Considering the strong influence of these fine particles on human health, these conclusions are relevant for the development of strategies to protect public health.
