For read-across substance, tris(2-ethylhexyl) benzene-1,2,4-tricarboxylate, sediment toxicity - NOEC = 740 mg/kg dry weight
In accordance with REACH Regulation
1907/2006, Annex X, Column 2, studies of the effects on sediment
organisms need be conducted if exposure assessment indicates a concern
for exposure to that environmental compartment. The physico-chemical
properties of the substance, together with fugacity modelling, indicate
that it may be expected to be distributed into sediment should
environmental release occur. Potential effects of read-across substance,
tris(2-ethylhexyl) benzene-1,2,4-tricarboxylate, on the sediment
reworker, Chironomus riparius, have been investigated. The No Observed
Effect Concentration (NOEC), based on the number of emerged adult
insects, mean emergence time (development rate) and sex ratio of emerged
adults, was 1000 mg/kg dry weight based on the nominal concentration,
and 740 mg/kg dry weight based on the mean measured concentration of the
substance in sediment.
