Description of key information
OECD 208 (Servajean, 2003): NOEC = 17 mg/kg dw
Key value for chemical safety assessment
- Long-term EC10, LC10 or NOEC for terrestrial plants:
- 17 mg/kg soil dw
Additional information
In a study conducted according to the guideline OECD TG 208 (2000) the No Observed Effect Concentrations of TCPP as referred to the emergence of seedlings and to the early stages of growth of Triticum aestivum, Sinapis alba and Lactuca sativa was determined. The lowest NOEC determined in the tests was 17 mg/kg dry weight for emergence of L. sativa seedlings. The lowest NOECs determined for S. alba and L. sativa were 28 and 22 mg/kg respectively based on 21-day post emergence plant wet weight.
Correction for organic matter content in the test (1.4%) has not been made, as it would result in a more favourable value by PNEC derivation.
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.
