- Nominal and measured concentrations:
- 3 doses (4.5, 2.25, 1.50mg/l) and a control used
- Key result
- Duration:
- 14 d
- Dose descriptor:
- NOEC
- Effect conc.:
- 1.5 mg/L
- Nominal / measured:
- meas. (initial)
- Basis for effect:
- weight
- Duration:
- 14 d
- Dose descriptor:
- NOEC
- Effect conc.:
- 4.5 mg/L
- Nominal / measured:
- meas. (initial)
- Basis for effect:
- weight
- Duration:
- 14 d
- Dose descriptor:
- LOEC
- Effect conc.:
- 4.5 mg/L
- Nominal / measured:
- meas. (initial)
- Basis for effect:
- weight
- Validity criteria fulfilled:
- yes
- Conclusions:
- In a Study performed to OECD Guideline 204, ferrocene has a NOEC 1.5 mg/L. The only effect was a decrease in weight in the higher dosage groups
Reference
No fish at any dose died. Fish showed behavioural changes after 2 hours exposure
