Data source
Materials and methods
- Objective of study:
- bioaccessibility (or bioavailability)
Test guideline
- Qualifier:
- no guideline followed
- Principles of method if other than guideline:
- One liter of demineralised water has been adjusted to pH = 1.5 by adding HCl 37%; 300 ml of the previous solution has been spilled in one glass beaker and the temperature has been regulated at 37°C. Agitating sufficient quantity of the Ba-substance has been dissolved to reach a saturated solution keeping the temperature at 37 °C. After 15 minutes additional reaction time the solution has been filtered with preheated filtering equipment. The barium content in the filtrate has been determined by gravimetric analysis (the filtrate had for BaCl2*2H2O test a pH = 0.6).The objective of this study is to assess the dissolution of chemical compounds in different artificial physiological media. The test media are selected to simulate relevant human-chemical interactions (as far as practical), i.e. contact of a test substance with skin, a substance entering the human body by inhalation or by ingestion into the gastro-intestinal tract. The amount dissolved of the test item is specified by the mass concentration of the substance in the test media under the applied test conditions. The total dissolved amount will be determined by measuring the total vanadium concentration in solution. Additionally, V(IV) and V(V) will be separated by HPLC and detected by ICP-MS. The concentration of possible further species (i.e. V(III)) will be determined indirectly by subtracting the concentrations of V(IV) and V(V) from the total dissolved concentrations.

Results and discussion
Applicant's summary and conclusion
