Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

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.

Description of key information

Lowest available aquatic endpoints:

Short term toxicity to aquatic invertebrates: 2.4 mg/L (Daphnia pulex) (Am. Soc. Test. Mater. (1980) and U.S. EPA (1975); Smith et al., 1988).

Long-term toxicty to aquatic algae Desmodesmus subspicatus: 72 h-ERC10 = 5.3 mg/l (Directive 92/69/EEC, C.3; Hüls, 1994)

Additional information

There are aquatic ecotoxicological data from three trophic levels available (invertebrates, fish and alga). EC50 values for invertebrates range from 2.4 mg/L with Daphnia pulex (Smith et al., 1988) to 9.5 mg/L with Daphnia magna (Scholz, 1994). The marine brine shrimp revealed an EC50 = 78 mg/L in a 24 h static study. (Price et al., 1974). For fish the LC50(96h) was determined to be 3.2 mg/L in a 96h semi-static study with Brachydanio rerio according to Directive 92/96/ECC, C.1. (Scholz, 1995).

A 72h ErC50 of 11 mg/L was determined with the freshwater alga Desmodesmus subspicatus (Scholz, 1994) over a period of 72 h under static conditions in an OECD 201 study.

Long-term aquatic toxicity data are available for one trophic level. For the freshwater algae Desmodesmus subspicatus the 72 h-ERC10 was 5.3 mg/l.
