Ecotoxicological information

Short-term toxicity to aquatic invertebrates

Currently viewing:

Administrative data

Endpoint:
short-term toxicity to aquatic invertebrates
Type of information:
experimental study
Adequacy of study:
weight of evidence
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
study well documented, meets generally accepted scientific principles, acceptable for assessment
Justification for type of information:
The substance is chemically comparable with and a precursor of the substance in this registration.
The water solubility is nearly the same and the Log Kow ist significantly smaller than 0 for both.
Other comparable substances, such as 2-(2-methoxyethoxy)ethanol, show the same toxicological
profile.
For the scope of this registration, it is sufficient for risk assessment.
