“…In addition, Harrison et al [37] confirmed in their analysis of the non-exhaust emissions, from abrasion of the brakes and tyres and wear of the road surface, as well as from resuspension of road dusts, that the emitted particles have to be in both the course (PM 2.5-10 ) and fine (PM 2.5 ) fractions, with a larger proportion in the former. Our results agree with those obtained in the open literature [5,35,[37][38][39][46][47][48]53,[74][75]). Our clustering could be essential to assess particle impacts on air quality and human health and, in addition, could be used in effective control measures.…”

“…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].…”

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.

“…The ROS-generating and inflammatory properties of inhaled UFPs are also considered to drive genotoxic effects in the lungs via the formation of oxidative DNA lesions [ 38 , 39 ]. In addition, UFPs can carry mutagenic compounds deep into the lungs, which, depending on their bioavailability, can cause genotoxicity by the formation of bulky DNA lesions [ 40 , 41 ].…”

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.
