“…In the present study, the mean levels of BaP were 491.2 ng/m 3 , 445.9 ng/m 3 , and 423.4 ng/m 3 at El Giza, Ramsis, and Sphinx Square, respectively. However, there is no Egyptian standard for BaP or any other PAH compounds; BaP concentrations in the present study highly exceed the Italian guided levels for BaP (1.00 ng/m 3 ) [75] and the recommended level (0.25 ng/m 3 ) in Britain [76].…”

Airborne particulate samples were collected from three main squares (Ramsis, El Giza, and Sphinx) representing heavy traffic areas in Greater Cairo during the period of December 2015-February 2016, and analysed for polycyclic aromatic hydrocarbon (PAHs). The maximum concentrations of particle-bound PAHs were observed at El Giza, while the minimum levels were recorded at Sphinx. The levels of particle-bound PAHs in the square areas of Greater Cairo are higher than those found in many different locations in Egypt and around the world.The distribution of individual particle-bound PAHs as well as PAH categories, depending on the ring number in Ramsis, El Giza, and Sphinx, wasquite similar. This similarity implies similar emission sources of PAHs in the three square areas, with vehicle exhaust emissions being the dominant one. Benzo[b]fluoranthene (BbF), benzo[ghi]perylene (BGP), and indeno[1,2,3-cd]pyrene(IND) were the most abundant PAH compounds. Diagnostic concentration ratios of PAH compounds in the three square locations suggest that both petrogenic and pyrogenic sources emit these compounds. Moreover, they originate mainly from traffic emissions in the study areas. Based on the calculated benzo[a]pyrene equivalent (BaPeq) for the individual particle-bound PAH compounds, health risks associated with the inhalation of these compounds were assessed. Total carcinogenic activity (TCA) for all measured PAHs represented 20.03% (El Giza), 20.40% (Ramsis), and 20.60% (Sphinx) of the total PAH concentrations. Benzo[a]pyrene (BaP) and dibenz[a,h]anthracene (DBA) were the highest contributors to the total health risks; these accounted for 42.72% and 38.50% (El Giza), 41.79% and 39.17% (Ramsis), and 42.92% and 37.78% (Sphinx) of the TCA of all PAH compounds, respectively. These results indicate the importance of BaP and DBA as surrogate compounds for PAHs in the atmosphere of square areas of Greater Cairo.

“…Therefore, some researchers have suggested it is highly desirable to estimate ambient levels of carcinogenic PAHs using surrogate pollutants that are conventionally used to determine air quality parameters and are automatically measured at urban monitoring stations. CO, NO and NO x have been proposed (Menichini et al 1999). In this context, SO 2 could be considered to play the role as surrogate for carcinogenic PAHs in the atmosphere of Higashi Hiroshima.…”

“…Kotzias and Brussol (1999) and Gerasimov (2004) reported that nitration of PAHs was favored when the compounds were adsorbed onto particles rather than in the gas phase. Menichini et al (1999) simultaneously measured particle-bound carcinogenic PAHs, CO, and NO x at a street site. CO, NO, and NO x were parameters strongly correlated with PAH concentrations (R ¼ 0:92).…”

The focus of this research was on elucidation of the role of deciduous tree ecosystems in accumulation of fine-particle-associated polycyclic aromatic hydrocarbons (PAHs) and heavy metals on leaves of deciduous trees. The studied species were Tilia x euchlora (frequently infested by sooty mold fungi) and Pyrus calleryana (unaffected by sooty mold fungi). The selected species have similar leaf morphology and were exposed to identical environmental conditions. Intra-species comparison showed that moldy linden leaves accumulate significantly higher amounts of PAHs and metals than unaffected linden leaves. Inter-species comparison revealed that in the absence of sooty mold fungi, physico-chemical properties of epicuticular waxes, rather than the amounts of waxes, might play an important role in accumulation of particulate matter on leaves.The accumulation and/or degradation of a number of high-molecular-weight (HMW) PAHs on leaves was temperature dependent. The results show that the presence of sooty mold fungi on deciduous leaves alters either the accumulation modes and/or degradation pathways of PAHs on deciduous leaves. r
