Description of key information
Additional information
MMVF note Q fibres have no short-term toxicity to fish. No mortality or behaviouraleffects were observed during the guideline test. The LC10and LC50-values are thus indicated as > 1.60 mg/L (>1000 mg/L nominal concentration).
The short-term toxicity to fish test presented in the end-point 6.1.1 showed that MMVF note Q fibres have no adverse effects to fish. The leached species are inorganic ions and are leached at a level known not to show any long-term toxicity to fish (See 4.8 Water solubility). Consequently, no long-term adverse effect to fish is expected from the substance and thus carrying out such a study is not scientifically justified.
It is documented in the endpoint 6.1.3 that MMVF note Q fibres did not show acute toxicity to Daphnia magna at the highest tested dose level (1000 mg/L). Thus NOEL >= 1000 mg/L.
The endpoint 6.1.4 (long-term toxicity to aquatic invertebrates) study is waived as scientifically unjustified.
The short-term toxicity test to aquatic invertebrates demonstrates that MMVF note Q fibres have no negative effects to invertebrates. The leached species are inorganic ions and are leached at a level known not to show any long-term toxicity to invertebrates (See 4.8 Water solubility).
It is thus concluded that no adverse effect to invertebrates is expected on long-term from the substance.
It is shown that the test substance did not induce acute toxicity to algae (Pseudokirchneriella subcapitata) at the highest tested dose level (1000 mg/L). Thus NOEL >= 1000 mg/L.
The endpoint 6.1.7 (toxicity to microorganisms) study is waived. The leached species are inorganic ions and are leached at concentration levels known not to show any toxicity to microorganism and to levels not exceeding the level (see 4.8 Water solubility) that can be expected in the influent of the sewage treatment plant(See 4.8 Water solubility).
