Short-term toxicity to aquatic invertebrates
Administrative data
- Endpoint:
- short-term toxicity to aquatic invertebrates
- Type of information:
- read-across based on grouping of substances (category approach)
- Adequacy of study:
- key study
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Justification for type of information:
- 1. HYPOTHESIS FOR THE CATEGORY APPROACH (ENDPOINT LEVEL)
Dicarboxylic acids are organic compounds that contain two carboxylic acid functional groups. They have the general type formula HOOC-(CH2)n-COOH. The present defined category comprises dicarboxylic acids with straight carbon chain having a “n” value from 6 to 16.
The physical and chemical properties as well as the toxicology and environmental fate and effects show that substances in this category have a similar order of toxicological and environmental fate properties, which supports the grouping of these substances as a category. (see attached justification)
2. CATEGORY APPROACH JUSTIFICATION (ENDPOINT LEVEL)
There are number of unifying considerations justifying the similarity between these substances in some important aspects. These include:
(1) Similarity of Use: these dicarboxylic acids have several industrial uses in the production of adhesives, plasticizers, lubricants, copolymers (such as polyamides and polyesters), etc.
(2) Similarity of Functional groups: all these substances contain two common functional groups (2 carboxyl groups). The only difference between the substances of this group lies in the length of the carbon chain.
(3) Similarity of Physical / Chemical properties: the similarity of physical / chemical properties for these substances (see attached justification)
(4) Similarity of Metabolism: Dicarboxylic acids were shown to be rapidly absorbed from the gastrointestinal tract, introduced into the fatty acid catabolism and therefore extensively metabolized by the organism and excreted (Passi, S. et al, 1983).
(5) Similarity of Mammalian Toxicity: The constituents of this class have similar toxicological properties. They are not acutely toxic, irritating to skin or sensitizing. However, they all present, except for dodecanedioic acid, irritating effects on the eyes (from moderate to high effects). They do not produce systemic effects in repeated dose studies. They are neither mutagenic nor carcinogenic and do not produce developmental/reproductive toxicity. (see attached justification)
(6) Similarity of Environmental Toxicity and Fate Properties: The substances in this category have similar environmental effects properties. The environmental effects data are similar for most category members in that most members do not exhibit acute toxicity. (see attached justification)

Applicant's summary and conclusion
- Validity criteria fulfilled:
- yes
- Conclusions:
- Under the test conditions the substance did not cause immobilisation up to a limit test nominal concentration of 100mg/l.
- Executive summary:
The toxicity to aquatic invertebrates of the test substance was evaluated according to OECD Guideline 202. The test organisms were examined in a negative control and in a definitive test group with treatment of the test item at the nominal concentration 100 mg/l. No test organisms were immobilised in the negative control group of the definitive test group. In this limit test no immobilisation of the water fleas were observed and the EC50 was therefore determined to be >100mg/l.
