  • 6PPD - Wikipedia
    6PPD is an organic chemical widely used as stabilising additive (or antidegradant) in rubbers, such as NR, SBR and BR; all of which are common in vehicle tires [1] Although it is an effective antioxidant it is primarily used because of its excellent antiozonant performance
  • 6PPD-quinone | US EPA - U. S. Environmental Protection Agency
    Vehicle tires contain the chemical known as 6PPD to prevent tires from breaking down due to reactions with ozone and other reactive oxygen species in the air When 6PPD reacts with ozone in the air, it forms 6PPD-quinone Tires wear down through contact with roads, releasing particles into the environment
  • 6PPD - Washington State Department of Ecology
    6PPD is a chemical that prevents automotive tires from degrading (i e , breaking down) and helps them last longer When 6PPD is exposed to air, it reacts with ozone to create 6PPD-quinone (also known as 6PPDQ) 6PPDQ is lethal to coho salmon and can contaminate water systems
  • USGS Research on 6PPD-quinone: Where the Rubber Meets the Road
    Stormwater and road runoff are recognized forms of pollution that can contain chemicals harmful to fish and other aquatic animals This includes 6PPD-quinone, the oxidized form of the chemical compound 6PPD that is used to prevent tires from degrading and cracking, ensuring driver safety
  • 6PPD - Washington Department of Fish Wildlife
    All vehicle tires manufactured since 1960 contain 6PPD, the precursor to 6PPD-q 6PPD is an additive designed to extend product life by preventing synthetic rubber products from cracking Other products that contain 6PPD include footwear, artificial turf, and synthetic playground surfaces
  • 5 Things You Should Know About 6PPD and 6PPD-quinone
    6PPD [N-(1,3-dimethylbutyl)-N’-phenyl-p-phenylenediamine] is a chemical ingredient widely used in tires to stop cracking and help extend tire life 6PPD prevents the ozone in the air from destroying the rubber in ires When 6PPD reacts with ozone to protect the tire, it can form 6PPD- quinone (also known as 6PPDQ)
  • What We Know: 6PPD and 6PPD-quinone
    Multiple aspects of the lifecycle of 6PPD-q are under investigation This includes the factors that influence the formation of 6PPD-q in tires and tire wear particles (TWPs) in the environment, 6PPD-q’s leaching rates from TWPs, and its persistence and bioaccumulation potential
  • From Tread to Watershed: How Tire Wear Particle Chemicals 6PPD and 6PPD . . .
    Recent studies have demonstrated the widespread occurrence and toxicity of TRWPs and their associated chemicals (e g 6PPD, 6PPD-quinone, benzothiazoles, phthalate esters, polycyclic aromatic hydrocarbons, etc ) in both aquatic and terrestrial environments
  • Respiratory toxicity mechanism of 6PPD and 6PPD-quinone: An . . . - PubMed
    The widespread distribution of environmental contaminants poses a significant threat to public health N-(1,3-dimethylbutyl)-N'-phenyl-p-phenylenediamine (6PPD) and its ozone-derivative, 6PPD-quinone (6PPD-Q), are emerging pollutants that propagate through particulate matter and aerosols, exerting detrimental effects on the respiratory system
  • Advance Notice of Proposed Rulemaking on 6PPD and Its Transformation . . .
    EPA has issued an advance notice of proposed rulemaking (ANPRM) under Section 6 of the Toxic Substance Control Act (TSCA) to gather information on the potential risks associated with N-(1,3-Dimethylbutyl)-N′-phenyl-p-phenylenediamine (6PPD) and its transformation product, 6PPD-quinone
