Additional information


For Triglyme short-term aquatic ecotoxicity studies for all three trophic levels (fish, daphnia and algae) are available as well as studies on sludge respiration inhibition.

 Fish:  OECD 203   LC50 (96h)   > 5000 mg/L   Key Study
 Daphnia:  OECD 202  EC50 (48h)  > 5000 mg/L  Key Study
 Algae:  OECD 201  ErC50 (72h)  > 6000 mg/L  Key Study
 Microorganisms (Sludge)  OECD 209  NOEC (3h)  > 5000 mg/L  Key Study
     EC50 (3h)  > 5000 mg/L  Key Study

The short-term ecotoxicity data were used for the derivation of the PNEC aqua intermittent release (see Section 6 Triglyme PNEC).


Triglyme, Read across 21d Daphnia

For reasons given in the waiving statements Section 6.1.2 no long-term fish toxicity tests were carried out. Instead a Diglyme long-term invertebrate study with daphnia was established. This 21d daphnia study with Diglyme was used for read across to Triglyme (see Section 6.1.4) for justification.

Algae: OECD 201   ErC10 (72h) 3000 mg/L   Key Study
 Daphnia:  OECD 211  NOEC (21d)  320 mg/L  Read Across from Digylme

The algae ErC10 (72h) and the daphnia NOEC (21d) were used to derive the PNEC aqua for continous release (see Section 6 Triglyme PNEC).
