Description of key information
GLP/guideline compliant 21 d seedling emergence and growth tests in six species of terrestrial plants.
Guideline compliant 21 d seedling emergence and growth test in T. pratense.
Key value for chemical safety assessment
- Long-term EC10, LC10 or NOEC for terrestrial plants:
- 20 mg/kg soil dw
Additional information
The toxicity of TBBPA to terrestrial plants was tested in 2 studies:
1) Porch et al. (2002): 21 d seedling emergence and growth test in six species of terrestrial plants at nominal concentrations of 0, 20, 78, 313, 1250, 5000 mg/kg dry soil. The test species were Corn (Zea mays), Cucumber (Cucumis sativa), Onion (Allium cepa), Ryegrass (Lolium perenne), Soybean (Glycine max) and Tomato (Lycopersicon esulentum). There were no adverse treatment-related effects on soybean seedling growth; treatment-related effects on seedling growth were observed in corn, cucumber, onion, ryegrass, and tomato. The 21 d NOEC in 6 species of terrestrial plants ranged from 20 (cucumber) to 5000 (soybeans) mg TBBPA/kg dry soil.
2) Sverdrup et al. (2006): 21 d seedling emergence and growth test in T. pratense at nominal concentrations of 1, 10, 100 and 1000 mg/kg soil dw. The NOEC was determined to be ≥1000 mg/kg soil dw.
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.
