  • What are phthalates used for?
  • Phthalates Phthalates are commonly used as plasticizers and solvents in tire manufacturing (Staples et al., 1997). Studies have shown that higher concentrations of phthalates in airborne particles are associated with traffic-related sources (Wang et al., 2018).
  • What are phthalate plasticizers?
  • From a chemical point of view, phthalate plasticizers come from an esterification reaction between phthalic anhydride and an alcohol with specific characteristics. Phthalates are the most used molecules in many sectors of industrial production.
  • What chemicals are used in tire production?
  • Several studies reported a variety of chemicals are used with tire production, including 2- [ (4-methylpentan-2-yl)amino]-5- (phenylamino)cyclohexa-2,5-diene-1,4-dione (6PPD-q), dimethyl phthalate (DMP), and diphenyl guanidine (DPG).
  • What causes tire & road wear microplastics (trwmps)?
  • Non-exhaust emission from motor vehicles is one of the main sources of tire and road wear microplastics (TRWMPs) worldwide (Pant and Harrison, 2013; Wagner et al., 2018), which are formed when tires rub the road.
  • What are the different types of phthalates?
  • Although the phthalates belong to a large family of molecular organic compounds, some molecules are used more than others. Among them, we remember DEHP, DINP, DIDP, DUP, and all the linear phthalates (ideal for providing high flexibility even at low temperatures).
  • What are some characteristics dependent on the presence of phthalates?
  • Some examples of characteristics dependent on the presence and quantity of phthalates into the plastic polymers are the degree of flexibility of the polymer, the resilience and the ability to migrate.
