Results and discussion
Toxicokinetic / pharmacokinetic studies
- Details on absorption:
- The most likely route of absorption considering the use of 5-nitrovanillin in dyeing is expected to be through the dermal route followed by the inhalation route. However, prediction values for dermal absorption do not indicate a high potential for dermal absorption (0.00600 mg/cm2/event)
Potential of absorption of this chemical by the inhalation route is also unlikely given that the particle size of the chemical is not in the inhalable size and the vapour pressure is also low (0.000794Pa) - Details on distribution in tissues:
- Given the poor water solubility of 5-nitrovanillin in water, it is expected that even if the chemical if absorbed within the living system, it is unlikely to be distributed to various parts of the living system through the blood. It may though be transerred to the other body parts via the plasma as it is more soluble in organic solvent.
- Details on excretion:
- 5-Nitrovanillin has very low bio-concentration factor (BCF ranging between 3.88 to 4.2). This is much less than the threshold value of 2000 to suggest bio-accumulation. Thus, the chemical is unlikely to bio-accumulate within the living system and shall be excreted out of the living system quickly either through the urine, excreta or bile
Metabolite characterisation studies
- Metabolites identified:
- no
- Details on metabolites:
- Not applicable
Applicant's summary and conclusion
- Conclusions:
- Interpretation of results (migrated information): other: No bioaccumulation potential based on WoE of various physico-chemical parameters and BCF value
The substance, 5 -nitrovanillin does not have a bioaccumulation potential based on weight of evidence of physicochemical parameters and low bio-concentration factor of the chemical. - Executive summary:
The substance, 5 -nitrovanillin does not have a bioaccumulation potential based on weight of evidence of physicochemical parameters and low bio-concentration factor of the chemical.
