Description of key information
Additional information
For Lemongrass oil (Cymbopogon flexuosus), no WAF studies on aquatic toxicity are available for Daphnia and algae. Read-across is conducted from Litsea cubeba, Cymbopogon winterianus and Eucalyptus citriodora. The rationale for this read-across is motivated in the read-across document. Key studies have been selected based on the highest toxicity (lowest EL50's).
An overview of the results of studies with reliability 1 and 2 is presented in the table below:
Test |
Reference |
Result (nominal, WAF tests) |
Daphnia OECD 202 Key study |
Harlan 2014 Reliability 2 Read-across to Litsea cubeba |
48h-EL50 = 4.2 mg/L |
Daphnia OECD 202 Supporting study |
Bayer AG 2000 Reliability 2 Read-across to Eucalyptus citriodora |
48h-EL50 = 20 mg/L |
Daphnia OECD 202 Supporting study |
Harlan 2013 Reliability 2 Read-across to Cymbopogon winterianus |
48h-EL50 = 6.0 mg/L |
Algae OECD 201 Key study |
Harlan 2013 Reliability 2 Read-across to Eucalyptus citriodora |
72h-ErL50 = 18 mg/L 72h-ErL10 = 12 mg/L |
Algae OECD 201 Supporting study |
Harlan 2014 Reliability 2 Read-across to Cymbopogon winterianus |
72h-ErL50 = 34 mg/L 72h-NOErL = 10 mg/L |
Algae OECD 201 Supporting study |
Harlan 2014 Reliability 2 Read-across to Litsea cubeba |
72h-ErL50 = 25 mg/L 72h-NOErL = 10 mg/L |
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
