“…In the second class of organic compounds, the contribution of BTEX remains constant, independently of the observation spot place. In a previous study, the results about total BTEX concentration showed a higher value at the exit position compared with middle position in the upward tube and a higher value in the upward tube with regard to the downward tube (Ameur-Boudabbous et al, 2012). No identical trend appears about the adsorption of BTEX on particles.…”

“…It seems difficult to identify a single source of ketone emission, but due to the significant use of ketones in building materials, the effect of particle redeposition would be preponderant. The benzaldehyde concentration inside the tunnel is lower, representing 0.4% of the total aldehyde emission (Ameur-Boudabbous et al, 2012). It is the same for the amount adsorbed on the particles.…”

“…Vehicles are only distinguished by their length: 12% of heavy-duty vehicle (>5 m) and 88% of lowduty vehicles. The geometrical characteristics of the urban tunnel have been indicated in a previous study (Ameur-Boudabbous et al, 2012). The tunnel length is around 1532 m with a slope of 3%.…”

“…Pena et al (2002) and Kawamura et al (2000) have established the importance of the oxidation of aldehydes as a relevant source of organic acids. In a previous study inside the same tunnel, five dominant aldehydes emitted by automotive traffic have been identified (Ameur-Boudabbous et al, 2012). Taking into account the humidity inside the tunnel, an aqueous oxidation of aldehydes can also be considered and contributes to generate organic acids.…”

“…The understanding of corrosion process involves knowledge of the real conditions of material exposure. In a previous study, it has been shown that among the gaseous pollutants identified, the SO 2 -NO 2 combination can be considered as an important factor during the corrosion process (Ameur-Boudabbous et al, 2012). The five dominant aldehydes emitted by automotive traffic-formaldehyde, acetaldehyde, butanal, propanal, and acrolein-representing 90-95% of total aldehyde emissions, will also have an accelerating effect on the corrosion process.…”

A tunnel-type semi-enclosed atmosphere is characterized by a higher particulate pollution than urban zones and highlights the particulate species having an impact on material degradation. Therefore, a transverse approach between air composition and its consequences upon longevity of materials is necessary, requiring a better knowledge of tunnel atmosphere and a better understanding of material degradation inside a tunnel for operating administration. The characterization of particulate matter collected inside a road tunnel in Rouen (France) allows us to set up the features of the particle characteristics of the real conditions of field exposure. Two sampling campaigns include analyses of organic and water-soluble ionic fractions. The current work shows that organic species, grouped into two sets derived primarily from engine exhaust and debris with wear particles resuspended by the traffic, are divided into two groups: a majority comprising n-alkanes, alkanoic acids, phthalates, ketones, and benzothiazole and a minority one composed of BTEX (benzene, toluene, ethylbenzene, and xylenes), polycyclic aromatic hydrocarbons (PAHs), fatty acid methyl esters (FAMEs), furans, phenols, and alkenes. As regards the water-soluble ionic fraction, the ionic species such as Cl, and Na þ are involved in the degradation process. The inorganic particles (insoluble and slightly soluble), debris and wear particles, organic acids, and relative humidity play a key role and are important factors to consider in the degradation process.Implications: Particles, together with relative humidity, can play an important role in the degradation of materials inside a road tunnel. Depth knowledge of the environment prevailing inside a tunnel improves the criteria for selection of materials of equipments contained therein. In the present study, it appears that the particulate mass can be divided into two groups with distinct effects: a water-soluble particle group is the source of ionic species involved in the degradation process, and a slightly water-soluble or insoluble particle group that acts as reservoir of condensed water when covering the surface of the material.

Secondary organic aerosol (SOA), a key constituent of fine particulate matter, can be formed through the oxidation of volatile organic compounds (VOCs). However, information on its relevant emission sources remains limited in many cities, especially concerning different types of land use. In this study, VOC concentration in Bangkok Metropolitan Region (BMR), Thailand, was continuously collected for 24 h by 6-L evacuated canister and analyzed by gas chromatography/mass spectrophotometry following USEPA TO15, and the formation of SOA was evaluated through the comprehensive direct measurements and speciation of ambient VOCs. Finally, source contribution of VOCs to SOA formation was characterized using the Positive Matrix Factorization (PMF) model. The results revealed the abundant group of VOCs species in the overall BMR was oxygenated VOCs, accounting for 49.97-57.37%. The SOA formation potential (SOAP) ranged from 1,134.33 to 3,143.74 μg m −3 . The VOC species contributing to the highest SOAP was toluene. Results from the PMF model revealed the dominant emission source of VOCs that greatly contributed to SOA was vehicle exhaust emission. Industrial combustion was the main source of VOC emission contributing to SOA in industrial areas. Sources of fuel evaporation, biomass burning, and cooking were also found in the study areas but in small quantities. The results of this study elucidated that different emission sources of VOCs contribute to SOA with respect to different types of land use. Findings of this study highlight the necessity to identify the contribution of potential emission sources of SOA precursors to effectively manage urban air pollution.
