Reference
Endpoint:
toxicity to aquatic algae and cyanobacteria
Type of information:
(Q)SAR
Adequacy of study:
weight of evidence
Reliability:
2 (reliable with restrictions)
Qualifier:
according to guideline
Guideline:
other: REACH guidance on QSARs R.6, May/July 2008
GLP compliance:
yes
Test organisms (species):
other: algae
Details on test organisms:
For freshwater algae, species frequently include Desmodesmus
subspicatus or Pseudokirchneriella subcapitata. For saltwater fish
equations, species include Menidia menidia (Altantic silverside),
Cyprinodon variegatus (Sheepshead minnow), and Menidia penisulae
(Tidewater silverside)

96 h
Key result
Duration:
96 h
Dose descriptor:
EC50
Effect conc.:
>= 1 085 - <= 1 143.768 mg/L
Validity criteria fulfilled:
no
Conclusions:
The predicted 96 hr EC50 is 1143.768 mg/L which indicated that the substance was not harmful to the water organisms in the environment.
The predicted 96 hr EC50 is 1085mg/L which indicated that the substance was not harmful to the water organisms in the environment.
Executive summary:

Based on the prediction result described above, the substance is no hazardous to aquatic exvironment
