SHORT-TERM TOXICITY

For Diglyme short-term aquatic ecotoxicity studies for all three trophic levels (fish, daphnia and algae) are available as well as studies on sludge respiration inhibition. The 96h fish study with Triglyme was used for read across to Diglyme (see Section 6.1.1) for justification

 Fish:  OECD 203   LC50 (96h)   > 5000 mg/L   Read across from Triglyme
 Daphnia:  OECD 202  EC50 (48h)  943 mg/L  Key Study
 Algae:  OECD 201  ErC50 (72h)  > 10000 mg/L  Key Study
 Microorganisms (Sludge)  OECD 209  NOEC (3h)  1067 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 Diglyme PNEC).

LONG-TERM TOXICITY

Algae: OECD 201   ErC10 (72h) 8318 mg/L  Key Study
 Daphnia:  OECD 211  NOEC (21d)  320 mg/L  Key Study

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