* 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.
