Description of key information

LC50 (14 d) for Eisenia fetida = 198.2 mg/kg soil dw (mortality, OECD 207)

Key value for chemical safety assessment

Additional information

The effects of OPP (CAS-No. 90-43-7) on earthworms were studied in an acute toxicity test on Eisenia fetida (Moser & Scheffczyk, 2004). ). This GLP study was carried out according to OECD Guideline 207.

In this test individuals of Eisenia fetida were exposed to different test concentrations of OPP. A LC50 (14 d) value of 198.2 mg/kg soil dw was determined. The NOEC for mortality as well as the NOEC for biomass was determined to be 125 mg test item/kg dw. Other effects on the morphology and the behaviour of the worms were not observed.
