Description of key information
Nitrification rate is significantly affected by MnCl2 spiking. The toxicity thresholds varied between soils and generally increased with an increasing background Mn concentration. The lowest NOEC was 207 mg Mn/kg.

- Long-term EC10 or NOEC for soil microorganisms:
- 207 mg/kg soil dw
Additional information
Nitrification rate is significantly affected by MnCl2 spiking. The toxicity thresholds varied between soils and generally increased with an increasing background Mn concentration. The lowest NOEC was 207 mg Mn/kg. The study was awarded a reliability score of 2 in accordance with the criteria set forth by Klimisch et al. (1997).
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
