A Review of N-(1,3-Dimethylbutyl)-N′-phenyl-p-Phenylenediamine (6PPD) and Its Derivative 6PPD-Quinone in the Environment

Toxics, Год журнала: 2024, Номер 12(6), С. 394 - 394

As an antioxidant and antiozonant, N-(1,3-Dimethylbutyl)-N′-phenyl-p-phenylenediamine (6PPD) is predominantly used in the rubber industry to prevent degradation. However, 6PPD can be ozonated generate a highly toxic transformation product called quinone (6PPD-quinone), which aquatic terrestrial organisms. Thus, 6PPD-quinone, two emerging contaminants, have attracted extensive attention recently. This review discussed levels distribution of 6PPD-quinone environment investigated their effects on series been widely found air, water, dust, while data soil, sediment, biota are scarce. cause teratogenic, developmental, reproductive, neuronal, genetic toxicity for organisms, at environmentally relevant concentrations. Future research should pay more bioaccumulation, biomagnification, transformation, mechanisms 6PPD-quinone.

N-(1,3-Dimethylbutyl)-N'-phenyl-p-phenylenediamine-quinone (6PPD-Q) has been identified as the cause of "urban runoff mortality syndrome." Thus, ecological risks substituted p-phenylenediamines (PPDs) and their quinone derivatives (PPD-Qs) in water have gained global attention. However, large-scale observation pollution characteristics surface is still lacking. Herein, a nationwide investigation revealed pervasive occurrence PPDs PPD-Qs riverine waters across China, with mean concentration ∑5PPD-Qs being 4.9 times higher than parent ∑5PPDs. Notably, 6PPD-Q concentrations at eight sampling sites exceeded median lethal for coho salmon. National annual fluxes were estimated 113.1 276.2 tonnes/year PPD-Qs, respectively, Yangtze River contributing more one-third total fluxes. The transformation to was dependent on atmospheric hydroxylation rates half-lives PPDs. A combined multimedia exposure assessment that accounted 82.5% human surpassing contributions from dust air exposure. This study provides comprehensive spatial picture China. national atlas highlights potential implies targeted actions should be taken mitigate PPD-Qs.
