“…It is important to note that light alkanes, alkenes, and d-limonene remained in the same order of magnitude as the other campaigns. To conclude, these results provide additional evidence that heavy alkanes can serve as the major aircraft signature emissions in air measurement affected by aggregate airport emissions-as found in our previous work as well as in the literature [17,[34][35][36]-which elevated dramatically when more outdoor emissions were allowed to enter indoors. Despite these different conditions, it is remarkable to observe very similar TVOC indoor concentrations and the occurrence of the same VOCs.…”

“…This implied that more outdoor pollutants (rich with aircraft exhaust and other airport-related emissions) were injected into the arrivals hall and got confined inside. The most prominent result was the enormous increase of the concentration of heavy alkanes up to 407 µg m -3 , around 40 times that of the other two campaigns, contributing by 66% of the TVOCs measured (Figure 2 and Tables S5 and S6) and remarkably mimicking the speciation observed in aircraft signature measurements presented in our previous work [34,35]. The other VOCs family affected by this irregular ventilation was the monoaromatics, reaching a concentration of 135 µg m -3 .…”

In Beirut–Rafic Hariri International Airport (RHIA), airport employees stay at least 12 h inside the airport’s buildings and suffer from respiratory symptoms. Additionally, direct openings exist between the apron and the arrivals hall providing a pathway for contaminated air to enter the buildings. Hence, we study the impact of Beirut–RHIA’s activities on the indoor air of the arrivals hall (impact on employees and passengers) during June, November, and October 2014. Due to their impacts on air quality and human health, assessing of the concentrations of nitrogen dioxide (NO2) and Volatile Organic Compounds (VOCs) was the target of our study by using gas chromatographic techniques (GC-MS and GC-FID) for VOCs and calorimetric methods for NO2 concentrations. NO2 levels indicated a probable hazard to the health of passengers and employees, while measured VOC levels did not present any risks except for acrolein. This is the first study to assess the speciation of a large number of VOCs (46 VOCs) for airport indoor air while revealing a very interesting correlation between aircraft number and the concentrations of VOC groups (namely heavy alkanes, aldehydes and ketones, and monoaromatics). Moreover, this is the first study in Lebanon to assess the speciation of a large number of VOCs in indoor air.

“…VOC compositions in jet exhaust varied with combustion power, and it was shown that light VOC emissions decrease as the engine power increases. Auxiliary power unit (APU) emissions were identified to be of the same order of magnitude as main engine emissions [ 93 ].…”

“…Levels of exposure reported in these studies are summarized in Table 1 . One study reported that personnel monitors measured higher levels compared to stationary equipment [ 87 ], and it was shown that ground support equipment, such as diesel-powered electrical generators and heaters [ 83 ] and auxiliary power units [ 93 ] contribute significantly to emissions.…”

A review of health effects associated with exposure to jet engine emissions in and around airports

Background Airport personnel are at risk of occupational exposure to jet engine emissions, which similarly to diesel exhaust emissions include volatile organic compounds and particulate matter consisting of an inorganic carbon core with associated polycyclic aromatic hydrocarbons, and metals. Diesel exhaust is classified as carcinogenic and the particulate fraction has in itself been linked to several adverse health effects including cancer. Method In this review, we summarize the available scientific literature covering human health effects of exposure to airport emissions, both in occupational settings and for residents living close to airports. We also report the findings from the limited scientific mechanistic studies of jet engine emissions in animal and cell models. Results Jet engine emissions contain large amounts of nano-sized particles, which are particularly prone to reach the lower airways upon inhalation. Size of particles and emission levels depend on type of aircraft, engine conditions, and fuel type, as well as on operation modes. Exposure to jet engine emissions is reported to be associated with biomarkers of exposure as well as biomarkers of effect among airport personnel, especially in ground-support functions. Proximity to running jet engines or to the airport as such for residential areas is associated with increased exposure and with increased risk of disease, increased hospital admissions and self-reported lung symptoms. Conclusion We conclude that though the literature is scarce and with low consistency in methods and measured biomarkers, there is evidence that jet engine emissions have physicochemical properties similar to diesel exhaust particles, and that exposure to jet engine emissions is associated with similar adverse health effects as exposure to diesel exhaust particles and other traffic emissions.

“…Indeed, properly tuning the size of the pores allows selective adsorption, thus diminishing the interferences due to the presence of other atmospheric organic pollutants during the analysis. The latter became necessary in high-polluted environments, as is the case of airports, where the concentration of VOCs can reach high concentrations [14,15]. Hence, to ensure a wider application of the GC prototype, a zeolite with pore size close to the BTEX cross-sectional areas [16] is highly desired.…”

The environmental impact of air pollution along with the registered detrimental effects on human health due to BTEX exposure have forced most countries to set limit values in public spaces and buildings, requiring the development of in situ devices able to quantify in (near)-real time the pollutants concentration, even at ppb levels. In 2 this work, several ZSM-5 zeolites with 79 < Si / Al < 316 have been synthesized and used as part of a pre-concentration unit connected to a miniaturized GC prototype, needed to drop the detection limit according to current legislation. The most important parameters influencing the multicomponent gas-phase adsorption of BTEX over ZSM-5 zeolites have been found to be the number of available acid sites (Al content), the zeolite pore size and its hydrophobicity. The experimental results demonstrate that a compromise between the hydrophobic character and the number of Al atoms should be found in order to properly design an adsorbent for near-real time BTEX detection.
