Description of key information

In a 21 day test with Oncorhynchus mykiss a LC5 value of 4 mg/l was reported (actual concentration). This value is considered to be equivalent to the NOEC for mortality. The test was conducted in very soft (12 mg CaCO3/l) natural water with daily renewal of the test water. 4 mg/l of fluorine anion equals 10.45 mg WF6.
lease note that WF6 is hydrolizing rapidly into HF and WOx compounds, when exposed to moisture. WF6 is not intended to get in contact with any environmental compartment and these values should be considered as only hypotheticaly.
