EC number: 809-920-4 | CAS number: 1047637-37-5
Short-term toxicity to aquatic invertebrates
Administrative data
Link to relevant study record(s)
Description of key information
Key value for chemical safety assessment
Fresh water invertebrates
Fresh water invertebrates
- Effect concentration:
- 42 mg/L
Additional information
Based on Read-Across with 2,2-Bis(chloromethyl)trimethylene bis[bis(2-chloroethyl)phophate
Test data
Two acute tests have been carried out with the invertebrate species Daphnia magna.
One of the tests (L'Haridon, 2002b) was conducted over a range of test concentrations, was supported by analysis of exposure concentrations and was subject to GLP. The test gave a 48-hour EC50 value of 42 mg/l. This result provides a suitable basis for deriving a PNECwater.
QSAR's
An estimated value of 81 mg/l has been derived for acute (48-hour LC50) toxicity to invertebrates using an ECOSAR QSAR applicable to esters. The value is consistent with those obtained in the reported studies.
