Description of key information
An examination of the acute toxicity of Dichloroacetyl chloride on zebrafish (Brachydanio rerio) with a total of 96 hours resulted in the following results: 1. at 3500 mg/L showed no lethality was observed (24 and 96 hours)
2. at 5000mg/L was observed mortality of 4/10 (24 hours) and mortality of 7/10 (96hours).
pH of the substance was 1.2 -1.6 and was tight with 10M NaOH and adjusted to the pH of the experimental water.
Key value for chemical safety assessment
Additional information
The acute toxicity of Dichloroacetyl chloride on zebrafish (Brachydanio rerio) was examined in 96 hours, static aquatic test. A total of 20 zebrafish was exposed to 3500mg/L and 5000mg/l concentration (nominal concentrations). The results are followed: at 5000 mg /L mortality occurred (48h: 4/10 and 96h: 7/10) and at 3500 mg/L no lethality was observed (48h: 0/10 and 96h: 0/10). No mortality was observed in the control group with 0 mh/L of Dichloroacetyl chloride.
The test was realized according to OECD Guideline 203, under GMP quality system. However, there is no evidence that the concentration of the substance was maintained during the test.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).
