basic assumption made in this hazard assessment and throughout this CSR,
(in accordance to the same assumption made in the EU RA process) is that
the ecotoxicity of zinc and zinc compounds is due to the Zn++ion.
As a consequence, all aquatic, sediment and terrestrial toxicity data in
this report are expressed as “zinc”, not as the test compound as such,
because ionic zinc is considered to be the causative factor for
toxicity. A further consequence of this is that all ecotoxicity data
obtained on different zinc compounds, are mutually relevant for each
other. For that reason, the available ecotoxicity databases related to
zinc and the different zinc compounds are combined before calculating
the PNECs. The only way zinc compounds can differ in this respect is in
their capacity to release zinc ions into (environmental) solution. That
effect is checked eventually in the transformation/dissolution tests and
may result in different classifications.
on studies conducted on substances representative of its individual
constituents, the test substance warrants classification as Aquatic
Acute 1 - H400 (Very toxic to aquatic life) and Aquatic Chronic 1
- H410 (Very toxic to aquatic life with long lasting effects) according
to EU CLP (1272/2008) criteria.
