A scum formed on the surface of molten zinc and zinc alloys.
tests not considered relevant when performed
-at pH 5.5
-at very high alkalinity/high hardness at pH 8.4

Study determined the influence of key water parameters on the acute
toxicity of zinc to Ceriodaphnia dubia. Tests done according to standard
protocol. Good quality and considered useful for setting the reference
value for acute aquatic ecotoxicity. Culture medium, test water
conditions well described and relevant the purpose of classification.
LC50 values: see “results” section.LC50 of 413 µg Zn/l observed at pH
6.5 is the reference value for classification at this pH.
