Key value for chemical safety assessment
Fresh water fish
Fresh water fish
- Dose descriptor:
- NOEC
- Effect concentration:
- 0.82 mg/L
Additional information
Dave et al (1981) report a 7 -day LC50 of 11.4 mg/L and a 10 -Day NOEC of 13.5 mg/L in Danio rerio. The same authors report a 50 -day NOEC for the embryo and larval stages of Oncorhyncus mykiss of 8.3 mg/L.
In a proprietary study summarised in the OECD SIDS, a NOEC of 0.82 mg/L is reported for a fish ELS toxicity test using Oncorhyncus mykiss. The reported lowest and thus most conservative NOEC value from this study was chosen as key value for chemical safety assessment.
