Description of key information
The chemical safety assessment according to Annex I of Regulation (EC) No 1907/2006 does not indicate the need to investigate further the toxicity to sediment organisms.
Key value for chemical safety assessment
Additional information
No experimental data evaluating the toxicity to sediment organisms are available for Reaction product of 1,3,5-Triazine-2,4,6-triamine, polymer with formaldehyde, methylated and C16-18 fatty alcohols. Only negligible releases into surface waters from sewage treatment plants are expected to take place due to the high adsorption potential of this substance, resulting in an effective removal in sewage treatment plants. Therefore, chronic exposure of sediment organisms is unlikely. Furthermore, the substance was found not to be toxic to aquatic organisms of different trophic levels up to the limit of its water solubility. Based on the available information, toxicity to sediment organisms is not expected to be of concern.
Intrinsic properties and fate
Reaction product of 1,3,5-Triazine-2,4,6-triamine, polymer with formaldehyde, methylated and C16‑18 fatty alcohols is not readily biodegradable (11 % biodegradation after 28 days; OECD 301B). However, as a result of the high adsorption potential of the substance (3.58 – 12.45 MCI method, KOCWIN v2.00), a removal from the water column to a significant degree by adsorption to sewage sludge can be expected (Guidance on information requirements and chemical safety assessment, Chapter R.7b, (ECHA, 2017)). Thus, only limited amounts will get in contact with activated sludge organisms in STPs and the concentration of the substance in effluents of conventional STPs is presumably marginal. On this basis, discharged concentrations of these substances into the aqueous/sediment compartment are likely to be negligible.
Considering this it can be assumed that the availability of Reaction product of 1,3,5-Triazine-2,4,6-triamine, polymer with formaldehyde, methylated and C16‑18 fatty alcohols in the sediment environment is low, which reduces the probability of chronic exposure of sediment organisms in general.
Aquatic ecotoxicity data
Acute aquatic toxicity data for two trophic levels (fish, algae) as well as chronic aquatic toxicity data for algae showed that no adverse effects occurred up to the limit of water solubility (< 15 µg/L at 20 °C and pH 6.3; OECD 105). Moreover, no toxic effects on activated sludge microorganisms were observed in an OECD 209 study as well as in the toxicity control of an OECD 301B study. The results indicate that Reaction product of 1,3,5-Triazine-2,4,6-triamine, polymer with formaldehyde, methylated and C16-18 fatty alcohols is likely to show no toxicity to sediment organisms either. It is not expected that results from additional studies with sediment organisms will lie out of the overall ecotoxicological profile of the substance.
Conclusion
Due to its high potential for adsorption to sewage sludge in conventional STPs, a removal from the water column to a significant degree will take place and only low concentrations are expected to be released (if at all) into the environment. If released into the aquatic compartment the substance will mainly partition to the sediment particles due to the low water solubility and high adsorption potential. Furthermore, all available aquatic toxicity data show that no acute or chronic effects occur up to the limit of water solubility. Therefore, Reaction product of 1,3,5-Triazine-2,4,6-triamine, polymer with formaldehyde, methylated and C16-18 fatty alcohols is unlikely to pose a risk for sediment organisms and testing is thus omitted.
