were derived for freshwater, saltwater, sediment, soil and
micro-organisms using the experimental data or equilibrium partitioning
results were identified for DCPD for the three trophic levels (algae,
invertebrates, and fish) with variable reliability. QSAR estimates are
acute key values gave an LC50 for freshwater fish of 15.7
mg/L, an EC50 for freshwater invertebrates of 0.823 mg/L and
an EC50 for freshwater algae of 22 mg/L. The chronic key
value gave a NOEC for freshwater fish of 0.98 mg/L, a NOEC for
invertebrates of 0.574 mg/L and an algal growth inhibition NOEC of 1.7
the acute key value for aquatic invertebrates is 0.823 mg/L, the
substance meets the criteria for acute classification category 1 under
CLP with the hazard phrase H400: ‘very toxic to aquatic life’ and this
has been added as a self-classification to the dossier. As the substance
is not readily biodegradable, the lowest chronic key value indicates
that DCPD meets the criteria for classification as Chronic Category 2
under CLP, with the hazard phrase H411: ‘toxic to aquatic life with long
