Description of key information
Additional information
The environmental hazard assessment of zinc diacrylate is based on data for zinc (as zinc compounds) and acrylic acid since the substance dissociates to these two constituents rapidly and completely in water. A very large database exists for zinc, from which only a selected number of acute studies are reported below. Available acrylic acid data is also presented. Overall, the available evidence suggests that the driver for environmental effects is the zinc ion. PNEC values for zinc acrylate were therefore extrapolated from those proposed for zinc in the EU Risk Assessment report using all adequate chronic data on fish, invertebrates, algae and plants considered together in a species sensitivity distribution (SSD). As a result of the analysis, a PNEC freshwater of 20.6 µg Zn/L was derived (ECB, 2008). This is equivalent to 169 µg zinc diacrylate/L.
