dc.description.abstract | [EN] A sampling campaign was conducted in the Liberdade Avenue tunnel (Braga, Portugal) during a week (with 56,000 vehicles) to monitor black carbon (eBC-equivalent black carbon) by means of an Aethalometer AE-31, and gaseous pollutants (CO2, CO, NOx). Inside the tunnel, the mean eBC mass concentration was 21 ± 10 μg m−3, reaching a maximum hourly value of 49.0 μg m−3. An hourly and weekday-weekend study was carried out. Regarding the Absorption Ångström exponent (AAE), a mean value of 0.97 ± 0.10 was obtained, for a source of practically pure traffic. There was a positive significant correlation between eBC and the number of light vehicles (r = 0.47; p < 0.001) and between eBC and the gaseous emissions: CO (r = 0.67; p < 0.001), CO2 (r = 0.71; p < 0.001), NO (r = 0.63; p < 0.001) and NO2 (r = 0.70; p < 0.001). The mean black carbon emission factors (EFBC) inside the tunnel were 0.31 ± 0.08 g (kg fuel)−1 and 0.11 ± 0.08 mg veh−1 km−1, similar to those found in other studies for gasoline and diesel vehicles in road tunnels | es_ES |

dc.description.project | Portuguese Science Foundation through the project “Source apportionment of URBan Emissions of primary particulate matter”, PTDC/AAC-AMB/117956/2010 (URBE). Special thanks are given to the Braga City Council, Municipal Police and University of Minho for all the logistic support. F. Oduber and C. del Blanco Alegre acknowledge the grants BES-2015-074473 and FPU16/05764 from the Spanish Ministry of Economy and Competitiveness and the Spanish Ministry of Education, Culture and Sports, respectively. This study was partially supported by the University of León (Programa Propio 2018/00203/001) and the AERORAIN project (Ministry of Economy and Competitiveness, Grant CGL2014-52556-R, co-financed with FEDER funds). Data treatment was carried out within the project “SOPRO - Chemical and toxicological SOurce PROfiling of particulate matter in urban air”, POCI-01-0145-FEDER-029574, funded by FEDER, through COMPETE2020 - Programa Operacional Competitividade e Internacionalização (POCI), and by Portuguese funds (OE), through FCT/MCTES | es_ES |
