  • Which derivatives of DPG are high-production-volume chemicals?
  • Several derivatives of DPG, BTH and BTR are high-production-volume chemicals. The annual aggregate production volumes of DPG, BTR, BTH, and 2- (morpholinothio)benzothiazole (2-morph-BTH) in the United States in 2015 were 454–9070, 454–4540, 720, and 454–9070 tons, respectively (Table 1).
  • What is DPG & BTH used for?
  • 1,3-Diphenylguanidine (DPG), benzothiazole (BTH), benzotriazole (BTR), and their derivatives are used in a wide range of industrial processes. DPG and BTH are typically used in the vulcanization of rubber and other polymers, including tires, plastics, and leather products (ECHA, 2020; ECHA, 2021; Li and Kannan, 2023b; Zhao et al., 2023).
  • What chemicals are used in vehicular traffic?
  • 1,3-Diphenylguanidine (DPG), benzothiazole (BTH), benzotriazole (BTR), and their derivatives are high-production-volume chemicals widely used in tires, corrosion inhibitors and plastic products. Vehicular traffic is an important source of these chemicals in the environment.
  • What is the distribution of DPG and TPG in indoor dust?
  • Our previous study showed a dominant profile of DPG (97 %), followed by DTG (2.5 %) and TPG (0.3 %) in indoor dust collected from the United States (Li and Kannan, 2023b). The distribution profiles of DPG, DTG and TPG concentrations in soils, tires and indoor dust were similar.
  • What is the concentration of DPG in road dust?
  • A German study measured DPG, 2-hydroxy benzothiazole (2-OH-BTH) and 2-amino benzothiazole (2-NH 2 -BTH) in road dust collected from two highway tunnels and reported concentrations in the range of 29,000–34,000, 1300–1500 and 120–130 ng/g, respectively (Klockner et al., 2021).
  • Is Roadside soil a source of DPG?
  • Although the major source of DPG is thought to be wearing of rubber products including tires, the difference in the magnitude of concentrations between roadside soil and house dust may be related to the size fraction and composition of these two matrices (Deng et al., 2022; Klockner et al., 2021).
