Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

* CS2 has a very short evaporation half life (several hours in water in a normal test). Therefore special precautions were taken to avoid evaporation. A 21 day study is not feasible.

** There were two independent tests with Poecilia Reticulata, the tests gave very comparable results with an LC50 of resp 3 and 4 mg/L.

The tests span several organisms and long term vs short term exposures. Based on these data the PNEC for aquatic systems equals the lowest NOEC/100 or 0.01 mg/L.
