physico-chemical oxygen consumption has been determined at 4000 mg/L
test item concentration. As
no physic-chemical oxygen consumption was observed at the that test item
concentration this observation also holds true for the lower test item
The toxicity of 2,3-dichlorobutadiene-1,3 to activated sewage sludge was
investigated in a respiration inhibition test according to EU Method C11
Activated sludge respiration inhibition 2008. Following three hours
exposure to 2,3-dichlorobutadiene-1,3 the EC50was
observed to be > 1000 mg/L (based on nominal exposure concentrations),
the corresponding EC10was calculated to be 163.8 mg/L.
