Additional information

Toxicity to fish

The 96-hour LC50 is 93 mg/L and the 96-hour NOEC is 22 mg/L.

Toxicity to daphnia

The nominal test item concentrations tested were 2.2, 4.6, 10, 22, 46 and 100 mg/L. Additionally, a control was tested in parallel.

The 48-hour EC100 is > 100 mg/L. The 48-hour NOEC is about 22 mg/L.

Toxixity to algae

The 72h EC50 values are 5.1 mg/L based on biomass and 11 mg/L based on growth rate. The NOEC and LOEC for both endpoints are 1.3 mg/L and 7.3 mg/L, respectively.

Toxicty to microorganisms

The 3-hour NOEC of Red LF 6382/18L-R to activated sludge microorganisms was determined to be 320 mg/L. The 3-hour EC50 could not be calculated due to the low toxic effect at the highest test concentration, but was higher than 1000 mg/L.
