Description of key information
Hyallella azteca: NOEC (mortality) = 0.06 mg a.i./L
Key value for chemical safety assessment
Additional information
Two reliable chronic sediment toxicity tests with two different species with different living and feeding conditions using spiked water are available for diuron. The study with the midge Chironomus riparius (Heimbach, 1993) was carried out according to a proposed method for a Sediment Toxicity Test developed by BBA/IVA ad hoc Working Group "Sediment Toxicity Tests" (Januar 1992). The resulting NOEC (emergence) value for this water/sediment-system was >4 mg a.i./L diuron. Gagliano & Bowers (1993) performed a Sediment Toxicity Test with Hyalella azteca according to ASTM E1383 -94 and found a NOEC (mortality) of 0.06 mg a.i./L (initial mean measured concentration) based upon no statistically significant difference in survivability and growth at this concentration compared to the control.
