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.

Additional information

Reliable results from short-term toxicity tests are available for freshwater fish (Oncorhynchus mykiss), invertebrates (Daphnia magna) and algae (Selenastrum capricornutum- new name Pseudokirchneriella subcapitata). The lowest LC50 or EC50 values determined for the three organisms were >16, >2.9 and >12 µg/L respectively. A NOEC of ≥12 µg/L was determined in the algal test.

NOECs of ≥14.4 μg/L (90-day) and ≥15 µg/L (21 -day) have been determined in longer-term tests with fish (early-life stages of Oncorhynchus mykiss) and invertebrates (reproduction and growth of Daphnia magna).

Sediment toxicity test results are available for the substance for three species. 28-day LC or EC50 values of 257 and >1272 mg/kg dry weight have been determined for effects on mortality of Chironomus riparius and Lumbriculus variegatus respectively. Corresponding NOEC values of 70, ≥1272 mg/kg dry weight based on growth rate and survival/reproduction/growth have been determined in the same tests. In addition, a 28-day NOEC of 130 mg/kg and a LOEC of >130 mg/kg have been determined for effects on growth rate in Hyalella azteca.
