ToxicityChemicalAcidReaction
Toxicity1
  • this preservative was extremely popular for many decades until arsenic toxicity and carcinogenicity was recognized by the US EPA and other regulators. (wikipedia.org)
Chemical1
  • Until then Wolman's formulation - famously known as Wolman Salts - contained dinitrophenol, a chemical manufactured by Hicksons, UK. (wikipedia.org)
Acid1
  • We found demographic differences in DF for 13 suspect EOAs and confirmed the presence of 6 priority novel chemicals: 2,4-Di-tert-butylphenol, Pyrocatechol, 2,4-Dinitrophenol, 3,5-Di-tert-butylsalicylic acid, 4-Hydroxycoumarin, and 2′-Hydroxyacetophenone (or 3′-Hydroxyacetophenone). (nih.gov)
Reaction2
  • Nevertheless since dinitrophenols are expected to be present partly in the particulate phase in the air, the reaction rate is expected to be even slower than the estimated value for the gas phase reaction (Atkinson R. et al. (europa.eu)
  • Phototransformation in water still would not be important in water (half-life of ≈500 days).This value is based on the reaction between 2,4-dinitrophenol, singlet oxygen (O2) and peroxy radicals (RO2) concentrations. (europa.eu)
