The antiozonant N-phenyl-N'-(1,3-dimethylbutyl)-p-phenylenediamine (6-PPD) is added to tires increase their lifetime and emitted with tire road wear particles into the environment. Recently, one of its transformation products (TPs), 6-PPD quinone (6-PPDQ), has gained attention due toxicity towards coho salmon. In this study, abiotic oxidative investigated by a series ozonation experiments in lab followed analysis TPs using liquid chromatography-high resolution-mass spectrometry (LC-HRMS). A...
Tire and road wear particles (TRWP) are generated in large quantity by automobile traffic on roads but their way of degradation the environment is largely unclear. Laboratory experiments were performed effect elevated temperature (simulating 2-3 years), sunlight exposure 0.5 years) mechanical stress physical properties chemical composition TRWP cryo-milled tire tread (CMTT). No significant effects observed applied mean pristine particles. After up to 40 % mass lost from TRWP, likely due loss...
Tire and road wear particles (TRWP) are formed at the frictional interface between tires surface. tread pavement materials denser than water but can be washed from surface into receiving bodies, ultimately depositing sediment, soil, or other media depending on environment. However, paucity of mass-based measurements has limited knowledge nature extent environmental concentrations necessary for risk assessment TRWP. Surface sediment samples were collected Seine River, France to characterize...
Tire and road wear particles (TRWP) are continuously formed by automotive traffic on roads. This study reports effects of long-term degradation over 2 years in water soil the presence microbes TRWP cryo-milled tire tread (CMTT). Degradation had little measurable effect physical properties TRWP; a shift towards larger particle sizes was mainly due to mechanical stress from stirring. The total quantified extractables (TQE) 27 chemicals transformation products determined were reduced 90 % CMTT...
Tire and road wear particles (TRWP), which contribute significantly to microplastic emission, are receiving more attention, but details about particle composition, translocation from source sink, particularly the possible effects on ecosystems largely unknown. We examined influence of native TRWP-containing sediments two settling ponds mortality behavior aquatic larvae Chironomus riparius. Both sediments, whether pure or mixed with different proportions quartz sand suspended in water, led...
Highlights• First study that analyzed TRWP in retained solid samples collected from a river.• concentrations solids were significantly higher than sediment.• SBR/NR ratio was lower expected based on passenger/truck tires literature.• to evaluate the temporal trend of river Lower over time are an indication water quality improvement.
