The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

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.



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.
