Water solubility
Administrative data
Link to relevant study record(s)
- Endpoint:
- water solubility
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 25 March 2022-15 July 2022
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- comparable to guideline study
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 105 (Water Solubility)
- Deviations:
- yes
- Remarks:
- As the test item is a dried sludge with no quantifiable markers (as per the COA provided), the visual observation is the approach adopted to determine the approximate solubility and no further testing is made.
- GLP compliance:
- yes
- Type of method:
- other: the visual observation is the approach adopted to determine the approximate solubility and no further testing is made.
- Key result
- Water solubility:
- < 0.001 g/L
- Conc. based on:
- test mat. (dissolved fraction)
- Temp.:
- 20 °C
- pH:
- >= 6.94 - <= 7.01
- Remarks on result:
- other: As the test item is a dried sludge with no quantifiable markers (as per the COA provided), the visual observation is the approach adopted to determine the approximate solubility and no further testing is made.
- Conclusions:
- The preliminary test indicated that the test item, Dried Sludge from Domestic Wastewater remained insoluble in double distilled water. Based on the preliminary solubility testing trials made, the approximate solubility of the test item in double distilled water was visually observed to be <0.0005 g/L at room temperature. As the test item is a dried sludge with no quantifiable markers (as per the COA provided), the visual observation is the approach adopted to determine the approximate solubility and no further testing is made.
- Executive summary:
The preliminary test indicated that the test item, Dried Sludge from Domestic Wastewater remained insoluble in double distilled water. Based on the preliminary solubility testing trials made, the approximate solubility of the test item in double distilled water was visually observed to be <0.0005 g/L at room temperature. As the test item is a dried sludge with no quantifiable markers (as per the COA provided), the visual observation is the approach adopted to determine the approximate solubility and no further testing is made.
