Abstract 6-PPDQ, an oxidation product of the antioxidant 6-PPD added to tire rubber, reaches the environment with tire abrasion on roads. Firm data on the environmental persistence of 6-PPDQ in different compartments is lacking. The microbial degradation of 6-PPDQ was studied in …

N-(1,3-Dimethylbutyl)-N′-phenyl-p-phenylendiamine (6-PPD) and one of its oxidation products, 6-PPD quinone (6-PPDQ) are environmental contaminants released from tire and road wear particles (TRWP). The abiotic transformation of both compounds by hydrolysis and in contact with atmosphere with and without oxygen species and simulated …

Tire and road wear particles (TRWP) are emitted in large amounts into the environment; a fraction of them becomes part of atmospheric aerosol. The degradation of four tire-derived chemicals, N-(1,3-dimethylbutyl)-N′-phenyl-p-phenylenediamine (6-PPD), its transformation product 6-PPD quinone (6-PPDQ), diphenylguanidine (DPG), and dicyclohexylamine (DCHA) …

Environmental context Each year, tonnes of tyre wear particles enter the terrestrial environment and undergo natural aging. This study investigates the effect of artificial weathering, particle concentration and preparation method on the reproduction of Caenorhabditis elegans, a soil- and water-dwelling nematode, using …

Tire particles can enter the marine environment e.g. through direct discharge of road runoff, sewage systems or riverine inputs. Their fate in marine waters remains largely unknown, though the deep sea could be a final sink as for other marine litter. To …

Para-phenylenediamines (PPDs) are antioxidants added to tires to protect the rubber. They are released from tire and road wear particles (TRWP) but the extent of their aerobic microbial degradation and the transformation products (TPs) formed are not known. Therefore, aerobic microbial degradation …
