Administrative data
Description of key information
Short-term toxicity to fish: TLm (48h) > 1000 mg/l
Short-term toxitiy invertebrates: EC50 (48h) > 100 mg/l (nominal)
Toxicity to aquatic plants other than algae: ErC50 (frond number, dry weight) > 100 mg/l (A.I., nominal)
Additional information
The toxicity potential of the substance to aquatic invertebrates and to aquatic plants other than algae was evaluated and the following results were obtained:
Fish: TLm (48h) > 1000 mg/l
Daphnia: EC50 (48h) > 100mg/l (nominal).
Lemna: ErC50 (frond number, dry weight) > 100 mg/l (A.I., nominal) and NOErC (frond number, dry weight) = 100 mg/l (A.I., nominal).
Justification for classification or non classification
According to the table 4.1.0 of the CLP Regulation (EC) No. 1272/2008, a substance shall be classified as Aquatic Category Acute 1 when:
96 hr LC50 (for fish) < 1 mg/l and/or
48 hr EC50 (for crustacea) < 1 mg/l and/or
72 or 96 hr ErC (for algae or other aquatic plants) < 1 mg/l.
Moreover, substance for wich adequate chronic toxicity data are not available shall be classified as:
- Aquatic Chronic 1 when:
96 hr LC50 (for fish) < 1 mg/l and/or
48 hr EC50 (for crustacea) < 1 mg/l and/or
72 or 96 hr ErC (for algae or other aquatic plants) < 1 mg/l
and the substance is not rapidly degradable and/or the experimentally determined BCF ≥ 500 (or, if absent, the log K ow ≥ 4)
- Aquatic Chronic 2 when:
96 hr LC50 (for fish)>1 to≤10 mg/l and/or
48 hr EC50 (for crustacea)>1 to≤10 mg/land/or
72 or 96 hr ErC (for algae or other aquatic plants)>1 to≤10 mg/l
and the substance is not rapidly degradable and/or the experimentally determined BCF ≥ 500 (or, if absent, the log K ow ≥ 4)
- Aquatic Chronic 3 when:
96 hr LC50 (for fish)>10 to≤100 mg/l and/or
48 hr EC50 (for crustacea)>10 to≤100 mg/land/or
72 or 96 hr ErC (for algae or other aquatic plants)>10 to≤100 mg/l
and the substance is not rapidly degradable and/or the experimentally determined BCF ≥ 500 (or, if absent, the log K ow ≥ 4)
The substance is not readily biodegradable and the effective levels for both aquatic invertebrates and aquatic plants is higher than 100 mg/l. A classification for aquatic toxicity (acute or chronic) according to the CLP Regulation (EC) No.1272/2008, is not proposed.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
