  • Is the prevalence of human exposure to diisononyl phthalate (DINP) underestimated?
  • The use of MINP as the sole biomarker for human exposure to diisononyl phthalate (DINP) is an underestimation. DINP is a complex mixture of branched-chain dialkyl phthalate isomers, predominantly containing nine carbons in the alkyl chain. Therefore, we concluded that the prevalence of human exposure to DINP is underestimated.
  • What is diisononyl phthalate (DINP)?
  • Diisononyl phthalate (DINP) is a complex mixture of predominantly nine-carbon branched-chain dialkyl phthalate isomers. It is analyzed as a metabolite in human urine (J Chromatogr B 805:161-167).
  • How does Di-isononyl phthalate affect the gastrointestinal tract?
  • Di-isononyl phthalate (DiNP), a common plasticizer used in polyvinyl chloride products, exhibits endocrine-disrupting capabilities. It is also toxic to the brain, reproductive system, liver, and kidney. However, little is known about how DiNP impacts the gastrointestinal tract (GIT).
  • Does Di-isononyl phthalate affect morphology and endocrine function?
  • Chiu, K., Bashir, S.T., Nowak, R.A. et al. Subacute exposure to di-isononyl phthalate alters the morphology, endocrine function, and immune system in the colon of adult female mice.
  • Are DINP phthalates dangerous?
  • Recently, DINP and other related phthalates have received publicity as potential environmental contaminants and raised concern for human health. There are few restrictions on these substances regarding acceptable levels in industrial wastes, liquid effluents, or workplace environments.
  • Does diisononyl phthalate cause hepatic and renal tissue injury?
  • Ma, P. et al. Oral exposure of Kunming mice to diisononyl phthalate induces hepatic and renal tissue injury through the accumulation of ROS. Protective effect of melatonin. Food Chem. Toxicol. 68, 247–256 (2014). Byers, S. L. et al. Mouse estrous cycle identification tool and images. PLoS ONE 7 (4), e35538 (2012).
