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.
