Drivers commonly navigate their vehicles at moderate speeds in proximity to traffic lights. In this study, road dust samples were collected the vicinity of lights, as well a taxi stand (TS) situated between with considerations given both forward direction (FD) and backward (BD). The characterization tire wear particles (TWPs) was meticulously conducted based on particle size. Notably, tire-road (TRWPs) conspicuously absent surpassing 500 μm. Furthermore, TRWPs comprised less than 1% identified 212–500 μm, origin traceable heavy rather passenger cars. abundance from exhibited marked variations, heightened prevalence TS BD opposed FD sample.

Microparticles such as tire-road wear particles (TRWPs) and road pavement (RPWPs) are generated by the friction between tire tread surface. TRWPs RPWPs on roads dispersed through traffic transferred to rivers seas via runoff accumulate in sediments. However, research generation of both TRWP RPWP has rarely been conducted. In this study, was investigated using a novel abrasion simulator equipped with paved bus tire, their contributions microparticles were examined.

Solution styrene–butadiene rubber (SSBR) is widely used to improve the properties of tire tread compounds. Tire wear particles (TWPs), which are generated on real roads as vehicles traverse, represent one significant sources microplastics. In this study, four SSBR compounds were prepared using two SSBRs with high styrene (STY samples) and 1,2-unit (VIN contents, along dicyclopentadiene resin. The abrasion behaviors investigated different testers: cut chip (CC), Lambourn, DIN, laboratory tester (LAT100). rates observed in Lambourn LAT100 tests consistent each other, but results CC DIN differed from them. addition resin improved rate resulted generation large particles. STY samples lower than those VIN samples, whereas values higher samples. predominantly larger 1000 μm, except for sample test. However, TWPs > μm rarely produced roads. size distributions 74.0–99.5%, 65.9–93.4%, 7.2–95.1%, 37.5–83.0% CC, tests, respectively. broader other test narrower. patterns morphologies by varied significantly, attributable differences bound crosslink densities, tensile properties.

Tire and road wear particles (TRWPs) are an appreciable source of microplastics (MPs); however, knowledge their large-scale occurrence mass flux based on robust sampling quantification is limited. Herein, the first city-wide survey TRWPs across environmental compartments (road dust, snowbank, water, sediment from rivers lakes) along four ring roads (beltways) in Beijing was performed. TRWP concentrations (n = 74) were quantified using bonded-sulfur as a marker to reveal spatial distributions adopted establish framework estimating emission factors (EFs) generation remote atmospheric, terrestrial, aquatic transport.

Among them, 61.3% eventually disposed landfills owing frequent sweeping high runoff treatment efficiency 18.1% stranded roadside; nevertheless, 11.9% escaped freshwater systems 5.7 3.0% transported land ocean, respectively. This study provides new insights into fate TRWPs.
