Additional information
The aquatic acute toxicity of Diacid 1550 was studied on fish, invertebrates, algae and microorganisms. The results are summarised in the table:
Study |
Value |
Remarks |
Fish 96h-LC50 Pimephales promelas |
15 mg/l |
Rel. 2, no GLP Cooke 1991 |
Invertebrates 48h-EC50 Daphnia magna |
22.5 mg/l |
Rel. 2, no GLP Cooke 1991 |
Algae 72h-EC50 Selenastrum capricornutum
|
62.9 mg/l |
Rel. 2, GLP study, Substance name not fully specified Goldsworthy 1991 |
Micro-organisms 48h-NOEC Activated sludge | 98 g/l | Rel. 2, no GLP study Goldsworthy 1991 |
For the preparation of the test media no solvent has been used. For the algae test (where the highest test concentrations were used), it was explicitly stated that the tested product (39% active ingredient) was water soluble and that no solvent was needed.
The fact that the tested product also contains other substances may explain why the test concentrations in the test media are above the water solubility stated for the main constituent (15 mg/l). In view of the explicit remark that the test substance was water soluble, the fact that the 15 mg/l limit is exceeded is not expected to impact the reliability of the test results.
The long-term aquatic toxicity was tested on fish and invertebrates. The results are summarised in the table:
Study |
Value |
Remarks |
Fish 35d-NOEC Danio rerio |
4.6 mg/l |
Rel. 1, GLP study according to OECD 210 |
Invertebrates 21d-NOEC Daphnia magna |
>4.83 mg/l |
Rel. 1, GLP study according to OECD 211 |
