  • How many plants use DEHP?
  • Some 800 plants in EU use DEHP or preparations with DEHP. The main use of DEHP is as a plasticizer in polymer products (in EU this is more than 95% of the total use of DEHP), mainly in flexible PVC. The content of DEHP in flexible polymer materials varies but is typically around 30% (w/w).
  • How reliable is DEHP data?
  • Reliable, relevant and adequate measured data for emissions is only available for a limited number of sites using DEHP (representing less than 5% of the total DEHP use).
  • Is DEHP a metabolite?
  • The metabolism of DEHP in mice corresponds partly to that in rats and partly to that in primates. For example, 2-ethyl-3-carboxypropyl phthalate, a main metabolite in rodents produced by the β-oxidation of DEHP, is formed in high concentrations in mice, but not in monkeys.
  • Is DEHP biodegradable?
  • The biodegradation of DEHP is varying in available studies. Based on the results of standard biodegradation test DEHP is readily biodegradable. Experimental data indicates a biodegradation half-life for DEHP in surface water of 50 days, and 300 days in aerobic sediment. Anaerobic conditions and low temperature further reduce the degradation rate.
  • How many tons of DEHP are produced per year?
  • The global annual production of DEHP exceeds 8 million tons (Wei et al. 2021). Because of its mass production, wide use in many products, and its chemical characteristics that can be easily migrated from flexible PVC, it is easy to be discharged into the external environment such as air, water, and soil.
  • Is DEHP toxic?
  • DEHP is very toxic and hazardous to organism health but is being widely used in our daily lives. DEHP exposure has been shown to have many adverse effects not only on animals but also on humans. DEHP is observed in the blood samples and urine samples of people who are hospitalized more because of the use of medical devices.
