Description of key information
In assessing the aquatic toxicity of magnesium 2-ethylhexanoate, read-across to the assessment entities soluble magnesium substances and 2-ethylhexanoic acid is applied since the ions of magnesium 2-ethylhexanoate determine its toxicity in the environment.
Magnesium as essential element for living organisms magnesium has a very low potential for toxicity to freshwater and saltwater organisms. However, experimental toxicity data are available for several species, although exceeding corresponding OECD test limits:
- an unbounded NOEC value of ≥ 500 mg/L magnesium was identified for microorganisms in activated sludge
- the lowest inhibitory concentration amounts to 121.3 mg/L magnesium for the green algal species Chlorella vulgaris
- a 48-h LC50 of 140 mg/L magnesium (Daphnia magna) represents the lowest value identified for freshwater invertebrates
- 96h-LC50 values ranging from 541 to 610 mg/L magnesium were determined for the toxicity of different magnesium sals and the freshwater fish Pimephales promelas.
- 48h-LC50 values of 4740 and 2800 mg/L magnesium were determined for saltwater fish species Cyprinodon variegatus and Menidia beryllina, respectively.
In sum, magnesium has a very low potential for acute aquatic toxicity.
2-ethylhexanoic acid
Acute data are available from studies for three trophic levels: algae, invertebrates and fish
- a 72-h ErC50 of 49.3 mg/L was identified for the algae Desmodesmus subspicatus (acc. To DIN 38412 part 9)
- a 48-h EC50 of 85.4 mg/L represents the lowest value identified for the invertebrate species Daphnia magna
- an unbounded value of > 100 mg/L (96-h LC50) was identified for the freshwater fish species Oryzias latipes based on data of an analogous substance (sodium 2-ethylhexanoate). Further studies of 2-ethylhexanoat with the freshwater fish species Oncorhynchus mykiss, Lepomis gibbosus and Leuciscus idus resulted in 96-h LC50 values > 100 mg/L
In sum, 2-ethylhexanoic acid has a low potential for acute aquatic toxicity.
Chronic data are available from studies for algae, aquatic invertebrates and microorganisms:
- a 72-h EC10 of 32.0 mg/L was identified for the green algae Desmodesmus subspicatus (acc. To DIN 38412 part 9)
- 21-d NOEC values of 18 mg/L and 25.0 mg/L were identified for Daphnia magna.
- a 17-h EC10 of 71.7 mg/L was identified for the inhibition of bacterial growth (Pseudomonas putida)
In sum, 2-ethylhexanoic acid has a very low potential for chronic aquatic toxicity to algae and invertebrates and appears to be of low toxicity to microorganisms.
Magnesium 2-ethylhexanoate
Using existing aquatic toxicity data of the dissociation products of magnesium 2-ethylhexanoate, the aquatic hazard assessment is based on the most toxic moiety.
Regarding acute (short-term) toxicity, magnesium has a very low potential. Existing aquatic toxicity data of 2-ethylhexanoate are recalculated for magnesium 2-ethylhexanoate based on a maximum 2-ethylhexanoate content of 92.18 %:
- a 72-h ErC50 of 53.5 mg/L was identified for the algae Desmodesmus subspicatus (acc. To DIN 38412 part 9)
- a 48-h EC50 of 92.6 mg/L represents the lowest value identified for the invertebrate species Daphnia magna
- an unbounded value of > 108.5 mg/L (96-h LC50) was identified for the freshwater fish species Oryzias latipes. Further studies with the freshwater fish species Oncorhynchus mykiss, Lepomis gibbosus and Leuciscus idus result in 96-h LC50 values > 108.5 mg/L
In sum, magnesium 2-ethylhexanoate has a low potential for acute aquatic toxicity.
Regarding chronic (long-term) toxicity, magnesium has very low potential. Existing aquatic toxicity data of 2-ethylhexanoate are recalculated for magnesium 2-ethylhexanoate based on a maximum 2-ethylhexanoate content of 92.18 %:
- a 72-h EC10 of 34.7 mg/L was identified for the green algae Desmodesmus subspicatus (acc. To DIN 38412 part 9)
- 21-d NOEC values 19.5 mg/L and 27.1 mg/L were identified for Daphnia magna.
- a 17-h EC10 of 77.8 mg/L was identified for inhibition of bacterial growth (Pseudomonas putida)
In sum, magnesium 2-ethylhexanoat has a very low potential for chronic aquatic toxicity to algae and invertebrates and appears to be of low toxicity to microorganisms.
