Description of key information
The test item was tested in two acute fish toxicity tests, as part of a large screening project. The studies were conducted 1984 and 1985 as non-GLP studies according to EPA-testing methods and published later on. The test design included analytical monitoring of the test samples, exposure period was 96 hours. Loss of concentration over test period ranged from 0 up to 15.9%
Comparable results were obtained in both tests (expressed as measured concentrations). The LC50 values were found to be 14.2 mg/l and 16.5 mg/l.
Key value for chemical safety assessment
Fresh water fish
Fresh water fish
- Effect concentration:
- 14.2 mg/L
Additional information
In conlusion, it can be stated, that based on the LC50 -values of 14.2 and 16.5 mg/l observed in the two tests, the substance has to be regarded as
"R52/53 - Harmful to aquatic organisms, may cause long-term adverse effects in the aquatic environment" according to Directive 67/548/EEC (DSD) or
"H412 - Harmful to aquatic life with long lasting effects" according to Regulation 1272/2008/EC (CLP).
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.
