Not all of identified test data on TDCO are considered acceptable
for determining PNEC values or for setting an environmental
classification. Only the acceptable data have been used for the purposes
of determining a PNECaquatic.
The lowest values available for the
preferred end points are as follows:
toxicity to fish: 96hr
toxicity to invertebrates: 48hr
toxicity to algae: 72hr
toxicity to fish (6 months growth and reproduction test): 6m NOECweight
= 2 µg/L
toxicity to invertebrates (21day repro test): 21day
toxicity to algae: 72hr

Fish were marginally more susceptible to TDCP in the acute tests
than the invertebrate,Daphnia magna, and the two species of
algae. Long-term data for the fish D.rerio showed that fish were
several orders of magnitude more sensitive than invertebrates/algae when
Based on this data TDCP has been classified as H410: Very toxic to
aquatic life with long lasting effects. (Aq.Chronic Cat.1).
As TBCP is not considered as rapidly biodegradable, a chronic M-factor
of 10 is applicable.
Additional information for the terrestrial compartment
The lowest toxicity values (corrected,
where appropriate, for standardised organic matter content of 3.4% and a
conversion factor of 1.13 for transforming results from a dry weight to
wet weight basis) are as follows:
