Road tunnels act like large laboratories; they provide an excellent environment to quantify
atmospheric particles emission factors from exhaust and non-exhaust sources due to their …

This study aims to quantify exhaust/non-exhaust emissions and the uncertainties associated
with them by combining innovative motorway tunnel sampling and source apportionment …

Real-world emission factors of PM2. 5 (particle's aerodynamic diameter of less than 2.5 μm),
NOx (the sum of NO2 and NO), and CO from mixed vehicles in the Shing Mun Tunnel in …

In India, there is uncertainty in vehicular emission estimation due to the lack of reliable
emission factors (EFs) that represent the real-world driving conditions. In this study, real …

On-road particulate matter (PM) mass was measured during a sampling campaign in March
of 2015 in the '4 giornate'tunnel in Naples, Italy. Two sets of samples were collected at both …

Emission factors of various particle species from light-and heavy-duty vehicles (LDVs and
HDVs, respectively), including organic and elemental carbon (OC and EC), sulfate …

Little is known about the characteristics of particulate matter emissions from vehicles in
China, although such information is critical in source apportionment modeling, emission …

In order to address road traffic emissions, studies need to be performed under realistic
driving conditions where the input from other sources is minimised. Measurements in traffic …

Total and speciated particulate matter (PM2. 5 and PM10) emission factors from in-use
vehicles were measured for a mixed light-(97.4% LD) and heavy-duty fleet (2.6% HD) in the …

Road traffic is one of the main sources of particulate matter in the atmosphere. Despite its
importance, there are significant challenges in quantitative evaluation of its contribution to …
