Applicant's summary and conclusion
- Conclusions:
- The effective concentration (EC50) value of 5-hydroxyisopthalic acid in algae Pseudokirchneriella subcapitata in a 72 hr study on growth effect was estimated to be 179.2994 mg/L..Thus considering CLP Criteria for aquatic classification of the substance , it is concluded that 5-hydroxyisopthalic acid shall not exhibit short term toxicity to green algae Pseudokirchneriella subcapitata.
