Test conditions
- Hardness:
- 0.24 mmol/L (= 24 mg/L) as CaCO3
- Test temperature:
- Water temperature: 22.7 to 23.1 °C
- pH:
- at test start: 7.8 to 8.0

- No information
- Nominal and measured concentrations:
- Nominal: 100, 33.3, 11.1, 3.70 and 1.23 mg test item/L
All reported results refer to nominal values since most of the measured concentrations of the carbon content of the test item were not quantifiable because of the poor solubility of the test item. - Details on test conditions:

Applicant's summary and conclusion
- Validity criteria fulfilled:
- yes
- Conclusions:
- The influence of Soya flour on the growth of the freshwater green algae Pseudokirchneriella subcapitata was assessed in a static concentration-response test.
The 72-hour EyC50 was calculated to be 65.4 mg test item/L, and the 72-hour ErC50 value was calculated to be > 100 mg test item/L.
The 72-hour NOEyC was determined to be 33.3 mg test item/L and the associated 72-hour LOEyC was 100 mg test item/L. The 72-hour NOErC was determined to be 11.1 mg test item/L and the associated 72-hour LOErC was 33.3 mg test item/L.
All reported results refer to nominal values since most of the measured concentrations of the carbon content of the test item were not quantifiable because of the poor solubility of the test item.
