Table 1. Summary of findings.
Long term: In accordance with section of REACH Annex XI the long term
toxicity to sediment organisms study does not need to be conducted
because it is technically not possible. Short term: (6 d) EC50 >1000
mg/kg dw soil H. incongruens.
A 6 d EC50 value of >1000 mg/kg dw soil (1.3% organic carbon)
has been determined for the effects of the test substance on population
numbers of the ostracod Heterocypris incongruens (Shell, 2004).
This study was conducted using a mixture of water and soil as a
The study reflects the only value that is available for this endpoint.
Testing for sediment toxicity is not considered necessary because:
In accordance with Annex XI, section 2, the long-term toxicity effects
studies to sediment dwelling organisms (required in Section 9.5.1) do
not need to be conducted as the study is technically not possible. This
is due to the very short sediment half-life once desorbed (see the
discussion of Biodegradation in water and sediment for further details),
preventing maintenance of exposure concentrations for the duration of
either a standard short-term or long-term test. Therefore, sediment
hazard assessment is based on the EQPM PNECs derived from the aquatic
PNECsediment has been calculated from PNECfreshwater on the basis of the
equilibrium partitioning method.
