Toxicity to terrestrial plants
Administrative data
- Endpoint:
- toxicity to terrestrial plants: long-term
- Type of information:
- migrated information: read-across from supporting substance (structural analogue or surrogate)
- Adequacy of study:
- other information
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- other: see 'Remark'
- Remarks:
- Method not in accordance with guideline standards but data are comprehensible and scientifically acceptable. Standard test organism was used. Glass house experiment. Since four harvests were considered, results of this study are appropiate for assessing the chronic toxicity of copper to plants.

Any other information on results incl. tables
The author grew perennial ryegrass (Lolium perenne) in a loam soil amended with copper at concentrations of 9.5, 95.3 and 953 mg/kg (dry weight). Significant reductions in dry weight of shoots and roots over 4 harvests were observed only at the highest concentration.
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.
