p-phenylenediamines and p-phenylenediamine quinone derivatives in,ippd and dnpd were detected in rubber cables, dnpd and cppd were mainly detected in rubber tape, and cppd was detected in rubber gloves and rubber tubes. it is worth noting that ppds reportedly cause allergic contact dermatitis, which commonly affects the hands ( bacharewicz-szczerbicka et al., 2021 , buttazzo et al., 2016 ).
new evidence of rubber-derived quinones in water, air, and soil
five p-phenylenediamine-derived quinones have been identified to be pervasive in roadside soil, runoff water, and air particles, while their health risks remain elusive. research findings demonstrate the coexistence of five quinones from globally ubiquitous p-phenylenediamine antioxidants in urban runoff, roadside soils, and air particles. 1.
rubber antioxidants: tmq, 6ppd, ippd chemical products,antioxidants are substances that are used in rubber and plastic industries to prevent oxidation and decay of polymer materials. tmq, also known as polymerized 2,2,4-trimethyl-1,2-dihydroquinoline, is a widely used rubber antioxidant. it provides excellent protection.

rubber antioxidants and their transformation products mdpi,antioxidants are prevalently used during rubber production to improve rubber performance, delay aging, and extend service life. however, recent studies have revealed that their transformation products (tps) could adversely affect environmental organisms and even lead to environmental events, which led to great public concern about environmental occurrence and potential impacts of rubber.

a nation-wide study for the occurrence of ppd antioxidants and 6ppd,in conclusion, the three rubber antioxidants have gradually phase-out (zhu et al., 2016; matsumoto et al., 2013) and relatively low levels of cppd, ippd and 77pd were observed in road dust. the concentrations of σppds in urban trunk road dust samples were in the ranges of 7.90–727 ng/g, with a median of 68.3 ng/g.
- What are rubber antioxidants?
- Rubber antioxidants are defined as substances that could delay the aging of polymer compounds and prolong the service life of rubber products by inhibiting oxidation, heat, or light radiation . To date, the annual global consumption of rubber antioxidants is over 700,000 tons, accounting for about 40% of the total amount of rubber additives.
- Which rubber antioxidants are used in China?
- Amine antioxidants are the main rubber antioxidants produced and used in China, of which 6PPD and 2,2,4-Trimethyl-1,2-dihydroquinoline (TMQ, RD) have the highest production, accounting for more than 80% of the total amine antioxidants.
- How does a rubber matrix affect antioxidative performance?
- Obviously, the solubility/dispersity of the antioxidant within the rubber matrix is a key factor in determining the antioxidative performance, and the antioxidative efficiency of antioxidant increases with the dispersion state within the rubber matrix, owing to higher specific surface area available for termination of radicals.
- Can a rubber antioxidant enter the environment with tire-wear particles (Twps)?
- Recently, it was reported that the rubber antioxidant N - (1,3-dimethylbutyl)- N′ -phenyl- p -phenylenediamine (6PPD or antioxidant 4020), a typical tire rubber antioxidant, could enter the surrounding environment together with tire-wear particles (TWPs) [7, 8].
