“…However, in laboratory measurements, it could be less difficult to distinguish between the four non-exhaust sources (tire, road, brake wear and resuspension). For this reason, laboratory measurements have been enhanced through on-road-real driving emissions (RDE) in order to surpass the limitation of each technique (Belkacem et al 2021). In addition, laboratory studies are not suitable to represent the entire vehicle fleet, as tires and brakes that can change significantly between the performance and manufacturers specifications.…”

Despite the potentially harmful effects on health and environmental impacts correlated with non-exhaust emissions (e.g., brake, tire and road wear and resuspension), but very limited environmental research studies have measured the contribution of vehicle non-exhaust emissions in real-world measurements and at different road segment types. Therefore, to fill this gap in academic literature, the main purpose of this study is to collect the knowledge base required to orient towards more sustainable mobility. During July 2019, continuous real-world measurements of non-exhaust particles (NEPs) were recorded over three different road segment types (urban, rural and motorway) in the city of Bron, near Lyon (France). Data were obtained using a native algorithm based on the GRIMM analyzer, series 1.108 Portable Aerosol Spectrometer. Results have confirmed abundant fine/coarse non-exhaust particle emissions which increase with the average vehicle speed and during sharp acceleration/deceleration manoeuvers. Motorway area has recorded the highest particle number concentrations as compared to urban and rural areas, which reaches 1.85 × 10 7 cm −3 due to increased vehicle speed, pavement materials and abrupt vehicle acceleration and deceleration maneuvers. In addition, the highest PM ratio was registered on motorway area and the lowest PM ratio appeared on urban road due to vehicle speed. It has been concluded that NEPs depended on the changes in driving conditions and road pavement type.

“…Deterioration of air quality in every city in the world has become a major concern as environmental and health impacts have become highly significant [1][2][3][4][5][6]: there are more than 430,000 premature deaths every year in Europe and 7 million around the world per year [7][8]. In addition, chronic diseases such as asthma, cancers, pulmonary illnesses and heart diseases are associated with deterioration of air quality.…”

“…Effects of particle emissions by road traffic (exhaust and non-exhaust) on human health and environment have been regularly proven [1,3,[45][46][47][48]. The major observed impacts are related to cardiovascular system (strokes and ischemic heart diseases), lungs inflammations, asthma, chronic lungs diseases, cancers, pulmonary fibroses, … [12,[49][50][51][52][53][54].…”

“…Many given analyses are based on particle sizes (from nano and ultrafine to large particles, volatile, semi-volatile, organic and inorganic particles, …) but very rare analyses resulted in studies of these impacts according to the chemical composition of the emitted particles. In addition, environmental effects are numerous, for example: visibility impairment caused re-suspended particles and their dispersion [1,[55][56][57][58].

Non-exhaust road transport emissions, particularly tyre-pavement abrasion, contribute to poor air quality. This original work is on particle emissions caused by tyre-pavement abrasion in real driving conditions in urban, suburban and motorway areas. The collected data were analyzed according to the size, the number and chemical identification. Multivariate analysis provided clusters of size and chemical elements. Results showed the predominant particles (diameter φ < 1 µm and φ ε]1-2 µm]) for urban and suburban experiments, and ]1-3 µm] on motorways. A confirmed shift phenomenon at the close-to-the-source showed particles of large sizes [5-10 µm]. The obtained clusters were: 1. Aluminosilicate, iron compounds, silicate free of aluminum (70%). 2. Ferrosilicon, silica, compounds of calcium, manganese, iron oxide, compounds of aluminum, sulfur, copper and zinc (29%). 3. A mix of various traces (1%). This paper will contribute to the development of new green technologies dedicated to improving sustainable road transport.

“…Both the type of fuel and the mode of combustion determine the characteristics of UFPs, including chemical composition, particle size, surface area, and solubility. In Europe, road transport contributes to total UFPs of around 32% in Greece to about 97% in Luxemburg [ 23 ]. Emissions from road traffic can enter car, bus, and truck cabins [ 24 ], affect pedestrians, cyclists, etc., and thus cause high levels of personal exposure [ 25 ].…”

The adverse effects of air pollutants on the respiratory and cardiovascular systems are unquestionable. However, in recent years, indications of effects beyond these organ systems have become more evident. Traffic-related air pollution has been linked with neurological diseases, exacerbated cognitive dysfunction, and Alzheimer’s disease. However, the exact air pollutant compositions and exposure scenarios leading to these adverse health effects are not known. Although several components of air pollution may be at play, recent experimental studies point to a key role of ultrafine particles (UFPs). While the importance of UFPs has been recognized, almost nothing is known about the smallest fraction of UFPs, and only >23 nm emissions are regulated in the EU. Moreover, the role of the semivolatile fraction of the emissions has been neglected. The Transport-Derived Ultrafines and the Brain Effects (TUBE) project will increase knowledge on harmful ultrafine air pollutants, as well as semivolatile compounds related to adverse health effects. By including all the major current combustion and emission control technologies, the TUBE project aims to provide new information on the adverse health effects of current traffic, as well as information for decision makers to develop more effective emission legislation. Most importantly, the TUBE project will include adverse health effects beyond the respiratory system; TUBE will assess how air pollution affects the brain and how air pollution particles might be removed from the brain. The purpose of this report is to describe the TUBE project, its background, and its goals.
