Ecotoxicological information

Toxicity to aquatic algae and cyanobacteria

Administrative data

Endpoint:
toxicity to aquatic algae and cyanobacteria
Data waiving:
study scientifically not necessary / other information available
Justification for data waiving:
other:
Justification for type of information:
The aquatic toxicity of the substance is unlikely to occur because the substance is highly insoluble in water.
Cross-reference
Reason / purpose:
data waiving: supporting information
Reference
Endpoint:
water solubility
Type of information:
other: estimated from EPISUITE WSKOW (v1.42).
Adequacy of study:
key study
Study period:
2018-2019
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
results derived from a valid (Q)SAR model and falling into its applicability domain, with limited documentation / justification
Reason / purpose:
reference to other study
Remarks:
water solubility calculated from experimental value of logKow
Qualifier:
no guideline required
Principles of method if other than guideline:
EPISUITE WSKOW (v1.42).
Type of method:
other: QSAR ELABORATION
