Description of key information

LC50 = 864 mg/kg soil dry weight (Eisenia fetida, 14 days)
NOEC = 582 mg/kg soil dry weight (Eisenia fetida, 14 days)

Key value for chemical safety assessment

Short-term EC50 or LC50 for soil macroorganisms:
864 mg/kg soil dw
Long-term EC10, LC10 or NOEC for soil macroorganisms:
582 mg/kg soil dw

Additional information

In an acute toxicity tests with earthworms, the 14 -day LC-50 of sorbic acid was 675 mg/kg soil dry weight and the 14 -day NOEC was 455 mg/kg soil dry weight. Within the evaluation under the Biocidal Products Directive 98/8/EEC, the rapporteur member state Germany recalculated these endpoints to potassium sorbate, resulting in a 14 -day LC50 of 864 mg/kg soil dry weight and a NOEC of 582 mg/kg soil dry weight.
