Key value for chemical safety assessment

LC50 for freshwater fish:
52 mg/L

Additional information

Test data

Two acute toxicity tests have been carried out with the fish species Oncorhynchus mykiss (Rainbow trout).

One of the tests (L'Haridon, 2002) was conducted over a range of test concentrations, was supported by analysis of exposure concentrations and was subject to GLP. The test gave a 96-hour LC50value of 52 mg/l. This result provides a suitable basis for deriving a PNECwater.

QSAR's

Estimated values of 32 and 17 mg/l have been derived for acute (96-hour LC50) fish toxicity using ECOSAR QSARs applicable to esters and phosphate esters respectively. The values are consistent with those obtained in the reported studies.
