“…. These values were comparable with those determined in a secondary school located in the centre of Wroclaw, Poland [23], but higher than those measured inside schools at Tehran [24]. Several studies have reported that the presence of Fe and Al in PM is due mainly to road dust resuspension and also to industrial sources [25,26].…”

“…The concentrations of Pb determined in this study were comparable to those measured in Spain [27] and lower than those found in Poland and Tehran [23,24]. Although Pb has been found to be usually emitted from sources such as fuel and motor oil combustion, in the developed world the use of leaded gasoline decreased since 1990s due to national regulations, determining a drastic reduction of Pb levels in atmosphere.…”

This study aims to investigate the air quality in primary school placed in district of Taranto (south of Italy), an area of high environmental risk because of closeness between large industrial complex and urban settlement. The chemical characterization of PM2.5 was performed to identify origin of pollutants detected inside school and the comparison between indoor and outdoor levels of PAHs and metals allowed evaluating intrusion of outdoor pollutants or the existence of specific indoor sources. The results showed that the indoor and outdoor levels of PM2.5, BaP, Cd, Ni, As, and Pb never exceeded the target values issued by World Health Organization (WHO). Nevertheless, high metals and PAHs concentrations were detected especially when school were downwind to the steel plant. The / ratio showed the impact of outdoor pollutants, especially of industrial markers as Fe, Mn, Zn, and Pb, on indoor air quality. This result was confirmed by values of diagnostic ratio as B(a)P/B(g)P, IP/(IP + BgP), BaP/Chry, and BaP/(BaP + Chry), which showed range characteristics of coke and coal combustion. However, Ni and As showed / ratio of 2.5 and 1.4, respectively, suggesting the presence of indoor sources.

“…LMW PAHs accounted for 21%-49% of ∑PAHs; MMW PAHs accounted for 29%-39% of the total PAHs, whereas HMW species were dominant at each sampling site and accounted for 36%-49% of the total PAHs. This may be due to the fact that HMW PAHs have a relatively large surface area and are more likely to be adsorbed on the surface of the particles (Kong et al, 2010;Hassanvand et al, 2015). Moreover, HMW PAHs are less volatile than LMW PAHs, which mainly exist in the gas phase (Possanzini et al, 2004).…”

The relationships between polycyclic aromatic hydrocarbons (PAHs) in PM 2.5 in outdoor and indoor environments of hotels were examined in Jinan, China from January 6, 2016 to January 29, 2016. The mean concentrations of ∑PAHs for all sampling sites showed the following ascending order: suburban indoor (SUI, 39.58 and SUI were all less than 1, indicating that the PAHs were mainly infiltrated from the outdoor environment. At URI 2 , 2-ring and some 3-and 4-ring PAHs were mainly produced indoors due to cooking, whereas the 5-7-ring PAHs were mainly infiltrated from the outdoor environment. The diagnostic ratios and principal component analysis indicated that emissions from combustion of coal, biomass, diesel fuel and gasoline were the main sources of PAHs in the study area. The impacts of health risk assessment of PAHs suggested that the health risks in the outdoor environment were more severe than those in the indoor environment and the health risks in urban area were significantly higher than those in the suburban area in Jinan.

A high-performance liquid chromatographic method with a modified QuEChERS extraction for the determination of polycyclic aromatic hydrocarbons (PAHs) in blood serum was developed to investigate the internal exposure level and the carcinogentic toxicity contribution rate of PAHs for pregnant women in Nantong, China. Venous blood (n = 48) was collected in the local hospital and the internal exposure level of 16 PAHs and the contribution rate of carcinogenicity to pregnant women were analyzed. Among all of the detected PAHs, the detection rate of pyrene (77.08%) was the highest, followed by naphthalene (64.58%) and benzo[a]anthracene (BaA, 45.83%). The carcinogenicity contribution rate of BaA (37.37%) was the highest, followed by fluorene (32.96%) and acenaphthylene (22.01%). The results showed that many kinds of carcinogenic PAHs can be detected in the serum of pregnant women in Nantong city, among which BaA should be paid most attention because of its high internal exposure level and carcinogenic risk. Meanwhile, the origins of general PAHs in serum samples were analyzed using the characteristic ratio analysis method. The PAH pollution level of air samples (n = 42) during the collection time of blood samples was also analyzed to compare the possible correlations between the two different results.
