to column 2 of Regulation (EC) 1907/2006 Annex IX long-term toxicity
testing shall only be proposed if the chemical safety assessment
indicates the need to investigate further the effects on aquatic
organisms. The substance does not need further investigations due to the
following reasons. As the test substance is highly insoluble in water (<
0.01 mg/L) it is expected that sediments are, if at all, only exposed to
very small amounts of the test substance.
The Guidance on
information requirements and chemical safety assessment, Chapter R7.b
(ECHA, 2012) states that once insoluble chemicals enter a standard STP,
they will be extensively removed in the primary settling tank and fat
trap and thus, only limited amounts will get in contact with activated
sludge organisms. Nevertheless, once this contact takes place, these
substances are expected to be removed from the water column to a
significant degree by adsorption to sewage sludge (Guidance on
information requirements and chemical safety assessment, Chapter R.7b,
(ECHA, 2012)). Thus, only limited concentrations of the substance will
presumably be discharged to the aqueous/sediment compartment. Thus, due
to the low expected environmental concentrations of the substance a
chronic exposure of sediment organisms is unlikely.
no effects were observed to aquatic algae, daphnia and fish in the range
of water solubility. Since only low amounts of the test substance can be
expected in the aquatic environment and no adverse effects of the
substance are expected no long-term tests on sediment organisms should
