Description of key information

The lowest NOEC determined of TCPP in a study conducted according to the OECD 208 guideline was 17 mg/kg dry weight for emergence of seedlings of Lactuca sativa.

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.
