OECD 203

Oncorhynchus mykiss

96h-LC50

>95.3 mg/L

Key study, GLP, rel. 1

OECD 202

Daphnia magna

48h-EC50

>95.3 mg/L

Key study, GLP, rel. 1

OECD 201

Scenedesmus subspicatus (new name: Desmodesmus subspicatus)

72h-EC50

72h-NOEC

>95.0 mg/L

≥95.0 mg/L

Key study, GLP, rel. 1

OECD 209

Activated sludge (predominantly domestic)

30min-EC50

30min-NOEC

>412 mg/L

≥412 mg/L

Key study, GLP, rel. 1

OECD 211

Daphnia magna

21d-NOEC

21d-LOEC

≥248.4 mg/L

>248.4 mg/L

Key study, GLP, rel.1

 OECD 212  Danio rerio  9d-EC10 *  114.8 mg/L  Key study, GLP, rel.1
 ISO 14669 adapted  Tisbe battagliai (marine)  21d-NOEC  224 mg/L  Key study, GLP, rel.1

* OECD 212 - Danio rerio (zebra fish), 9 days, flow through: EC10 = 114.8 mg/L (inhibition of hatch, study day 4)

Thus GLDA is not classified as hazardous to the aquatic environment.
