Description of key information
Additional information
The test item was investigated on aquatic organisms of different trophic levels (bacteria, invertebrates, fish, algae and aquatic plants). Acute toxicity tests (96 h) on freshwater and marine fish species (bluegill sunfish, fathead minnow, rainbow trout and sheepshead minnow) resulted in LC50-values ranging from 0.320 mg a.i./L to 0.960 mg a.i./L. A chronic test on fathead minnow (early life stage study over 35 days) resulted in a NOEC of 0.46 mg/L for fry survival and is thus within the same range as the LC50-values determined in the acute tests.
Acute toxicity tests on freshwater and marine invertebrates (Daphnia magna and Americamysis bahia) resulted in higher effect values than the fish studies.The EC/LC50-values were in a range of 1.5 mg a.i./L to 9.88 mg a.i./L. A chronic study conducted on daphnids resulted in a NOEC of 0.34 mg a.i./L. In a marine 28-day study with A. bahia, the NOEC for mysid reproduction was 0.12 mg a.i./L. Thus invertebrates were less sensitive than fish in acute tests, nevertheless sensitivity of chronic endpoints of invertebrates is in the same range.
For freshwater and marine algae, the EC50 values ranged from 0.029 to 0.0761 mg a.i./L, with the NOEC values ranging from 0.0051 to 0.115 mg a.i./L. The marine diatom, Skeletonema costatum, had the lowest endpoint for marine algae.The most sensitive freshwater algae was the green alga, Pseudokirchneriella subcapitata.
Additionally a series of higher tiered tests was performed in order to determine the potential toxicity of the substance to Lemna and other higher aquatic plants under more realistic conditions. The substance is an herbicide therefore aquatic plants are sensitive to exposure as is expected from an herbicidal compound. Two longer-term outdoor studies were undertaken in order to examine the sensitivity of other aquatic vascular plants to the substance. The NOEC based on plant growth from the microcosm was 0.00032 mg a.i./L.
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).
