“…In this respect, this study is of interest for urban planning of green areas and infrastructures (e.g. Tong et al 2016). Our results suggest that placing tree belts near roads with traffic and tram stops would help absorb airborne micrometric magnetite particles thus improving general air quality.…”

“…"Roadside vegetation barriers have shown the potential to reduce near-road air pollution concentrations; however, the characteristics of these barriers needed to ensure pollution reductions are not well understood … Two potentially viable design options are revealed: a) a wide vegetation barrier with high Leaf Area Density (LAD), and b) vegetation-solid barrier combinations, i.e., planting trees next to a solid barrier. Both designs reduce downwind particle concentrations significantly" [24]. According to the study, "the tree species used for the GAIA-urban forestation project were selected, starting from the green Regulations of the City of Bologna and evaluating important factors such as the potential for absorption of pollutants (CO 2 and PM 10 ), the release of substances volatile and the allergenic specific factors, the first 24 most suitable species have been identified to fulfil this function" [25].…”

“…Deletraz & Paul (1998), les ETM ont une zone de forte influence variant entre 30 à 150 mètres de la chaussée et les HAP ont un important dépôt qui s'effectue dans la zone des 100 premiers mètres bordant la chaussée. Par ailleurs, selon Tong et al, (2016), la présence d'une importante quantité de végétaux le long des bordures des routes, comme c'est le cas de notre site d'étude (zone pré forestière), engendre également une diminution des concentrations de ces substances polluantes pendant leurs transports à des distances éloignées de la chaussée. Quant aux vers de terre collectés, contrairement aux substances polluantes, une augmentation de leurs densités par monolithe a été observée au fur et à mesure que l'on s'éloigne de la chaussée.…”
