*Smallest dilution factor that results in a 20% light emission reduction
EC 20 |
> 800 ml eluate/L |
The above values can be converted to toxicity for copper slag by taking into account the amount of slag used to produce the eluate : 100 g slag / 1000 ml water
EC 20 |
> 80 g copper slag /L |
Applicant's summary and conclusion
- Conclusions:
- An EC20 value of >80 g/L was observed.
- Executive summary:
Effect of water extracts of copper slags on the bioluminescence of Vibrio fischeri was assessed during a 30 min experiment. The test was performed according to DIN EN ISO 11348 -2. An EC20 value of >80 g/L was observed.
