“…Several studies have identified civil and military aircraft activity as a potential source of particulate matter emission near airport zones [1][2][3][4][5][6][7]. In particular, it was highlighted that aircraft activity could contribute to increasing the levels of fine and ultrafine particles (UFPs) in the surrounding environment, with potential effects on the health of the population in the vicinity of the emission source [8][9][10][11].…”

The occupational exposure to airborne fine and ultrafine particles (UFPs) and noise in aircraft personnel employed in airport taxiway was investigated. Stationary samplings and multiple personal sampling sites and job tasks were considered. Size distribution, particle number concentrations, lung dose surface area were measured by personal particle counters and by means of an electric low pressure impactor (ELPI+TM). Morphological and chemical characterization of UFPs were performed by transmission and scanning electron microscopy, the latter together with energy dispersive X-Ray spectroscopy based spatially resolved compositional mapping. A-weighted noise exposure level A-weighted noise exposure level normalized to an 8 h working day and Peak Sound C-weighted Pressure Level was calculated for single worker and for homogeneous exposure groups. Our study provides evidence on the impact of aviation-related emissions on occupational exposure to ultrafine particles and noise exposure of workers operating in an airport taxiway. Main exposure peaks are related to pre-flight operations of engine aircrafts. Although exposure to ultrafine particles and noise appears to not be critical if compared with other occupational scenarios, the coincidence in time of high peaks of exposure to ultrafine particles and noise suggest that further investigations are warranted in order to assess possible subclinical and clinical adverse health effects in exposed workers, especially for cardiovascular apparatus.

“…Some previous studies showed that the airport/airliner is also one of the main UFP sources in cities. However, its affecting area may be limited to rural-urban/near airport areas (Ren et al, 2016). PSD of particles emitted from diesel vehicle engines fall mainly in the range of 20-130 nm, while for petrol these are in the 40-80 nm range (Morawska et al, 2008;Ristovski et al, 2006).…”

Measurements of particle size distribution was made in one location of an urban area in the period January-September/2015 in order to understand the sources and mechanisms influencing ultrafine particle (UFP) number concentrations (PNC 2.5-250) using a Scanning Mobility Particle Sizer Spectrometer (SMPS). kmeans cluster analysis was applied to interpret the sources, temporal and spatial trends of UFP. Eight clusters were obtained. Main PSD patterns of each cluster, mean concentration of other air pollutants tracing specific sources and processes, and that of meteorological variables, as well as the hourly and seasonal frequencies of occurrence were used to support the interpretation of their origin. Thus, clusters were attributed to traffic rush hours, midday summer new particle formation, diurnal new particle formation and growth, growth of nucleated and other urban particles, urban background, regional and urban background and regional and urban background on cold nights. Many PSDs of the clusters were dominated by nucleation mode particles: midday nucleated fresh particles, photochemically induced (NPF); diurnal nucleation episodes (NPF2); growth of nucleated particles in nocturnal aging (GNPF). Origins of the clusters were related to local/regional sources (mostly traffic and biomass burning), atmospheric processes (photochemical formation and growth) and urban/regional background. Results clearly shows that traffic is a major UFP source in nucleation mode and occurred in higher concentrations in winter (08:00 to 12:00 h) during traffic rush hours, and at night. Photochemical nucleation occurred with a relatively low frequency but yielding very high PNC.

“…Generally, studies performed within or close to airports have reported increases in particles ranging from 4 to 100 nm in diameter and mostly distributed in the nucleation range (< 30 nm). For example, Mazaheri et al (2009) showed a main nucleation mode and an accumulation mode (40-100 nm) more evident during take-offs; Keuken et al (2015) reported PNSD dominated by 10-20 nm particles in an area affected by emissions from Schiphol airport (the Netherlands); Hudda and Fruin (2016) found strong increases in particles smaller than 40 nm downwind of Los Angeles International Airport; Ren et al (2016) showed that particles peaking at 16 nm dominate the PNSD at various distances from the runway of Tianjin International Airport, China; Masiol et al (2016) reported that the fingerprint of aircraft emissions sampled under real ambient conditions at the airport of Venice (Italy) has a main mode at approx. 80 nm and a second mode in the nucleation range below 14 nm.…”

Abstract. The international airport of Heathrow is a major source of nitrogen oxides, but its contribution to the levels of sub-micrometre particles is unknown and is the objective of this study. Two sampling campaigns were carried out during warm and cold seasons at a site close to the airfield (1.2 km). Size spectra were largely dominated by ultrafine particles: nucleation particles (< 30 nm) were found to be ∼ 10 times higher than those commonly measured in urban background environments of London. Five clusters and six factors were identified by applying k means cluster analysis and positive matrix factorisation (PMF), respectively, to particle number size distributions; their interpretation was based on their modal structures, wind directionality, diurnal patterns, road and airport traffic volumes, and on the relationship with weather and other air pollutants. Airport emissions, fresh and aged road traffic, urban accumulation mode, and two secondary sources were then identified and apportioned. The fingerprint of Heathrow has a characteristic modal structure peaking at < 20 nm and accounts for 30-35 % of total particles in both the seasons. Other main contributors are fresh (24-36 %) and aged (16-21 %) road traffic emissions and urban accumulation from London (around 10 %). Secondary sources accounted for less than 6 % in number concentrations but for more than 50 % in volume concentration. The analysis of a strong regional nucleation event showed that both the cluster categorisation and PMF contributions were affected during the first 6 h of the event. In 2016, the UK government provisionally approved the construction of a third runway; therefore the direct and indirect impact of Heathrow on local air quality is expected to increase unless mitigation strategies are applied successfully.
