Nominal concentration (mg/L)
Zebra fish were exposed to nominal 2,3-dichlorobutadiene-1,3 concentrations of 0 (control), 9.4, 20.7, 45.5 and 100 mg/L for 96 hours under semi-static conditions according to EU Method C.1 Acute toxicity to fish (2008). Analysis of new and 24 hour aged media was performed for each treatment and geometric mean values were calculated for each 24 hour exposure period. The 96 hr LC50based on the geometric mean measured concentrations was 1.39 mg/L, the corresponding no-observed effect concentration (NOEC) was observed to be 0.501 mg/L.
