Toxicity to terrestrial plants
Administrative data
- Endpoint:
- toxicity to terrestrial plants: long-term
- Type of information:
- experimental study planned (based on read-across)
- Justification for type of information:
- This study is ongoing according to ECHA Decision issued for the substance sodium potassium tartrate (source substance).
REPORTING FORMAT FOR THE CATEGORY APPROACH
1. HYPOTHESIS FOR THE CATEGORY APPROACH (ENDPOINT LEVEL)
Read-across can be performed because both source and target substances share the same group, the tartrate anion. The main assumption is that the presence in the molecules of hydrogen or sodium or potassium or calcium is not significant in respect of the assessment of toxicity to terrestrial plants. In dilute aqueous conditions of defined pH a salt will behave no differently to the parent acid (and viceversa), at identical concentration of the particular speciated form present and will be fully dissociated.
2. CATEGORY APPROACH JUSTIFICATION (ENDPOINT LEVEL)
All substances of the Category (tartaric acid and its sodium, potassium and calcium salts) are soluble (range from soluble to very soluble) in water. For all substances log Kow is negative (from -5.14 for potassium hydrogen tartrate to -0.76 for (+)-tatraric acid).

Results and discussion
Applicant's summary and conclusion
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
