Description of key information

Respirator sludge inhibition test for FAT 40543/A resulted in NOEC (3h) of 320 mg/L (highest concentration tested). The EC50 (3h) is therefore >320 mg/L.

Key value for chemical safety assessment

EC50 for microorganisms:
320 mg/L

Additional information

The toxicity of FAT 40543/A to activated sludge was determined in a 3-hours respiration inhibition test according to the EEC Directive 87/302, L 133/118 -122 and to the OECD Guideline No. 209.

The test substance concentrations tested were 320, 100, 32 and 10 mg/l. The reference substance, 3,5-Dichlorophenol was tested in concentrations of 32, 10 and 3.2 mg/l.

Results: IC50 (3 h) of the test substance FAT 40543/A > 320 mg/L, NOEC: 320 mg/L

IC50 (3 h) of the reference substance 3,5-Dichlorophenol : 11 mg/L
