Description of key information

The only relevant data (Pseudomonas putida, EC10 >2000 mg/l) originates from a secondary data source (handbook Verschueren 1996). No verification of the original study is possible. This data source is nevertheless mentioned in table R.7.1.-2 of chapter R 7.1.1.2 of the Guidance on information requirements and chemical safety assessment. Conducting a new study (activated sludge respiration inhibition test) was not considered scientifically relevant because of the very high volatility of 1,1-dichloroethene.Therefore 2000 mg/l is used as key value in the risk assessment.

Key value for chemical safety assessment

EC10 or NOEC for microorganisms:
2 000 mg/L
