No data on sediment toxicity are available. However, the substance is not persistent in the sediment compartment. The equilibrium partitioning method has been used for assessing the hazard to sediment organisms.
In Annex X of the Regulation (EC) No 1907/2006 concerning the
Registration, Evaluation, Authorisation and Restriction of Chemicals
(REACH), it is suggested, that "long-term toxicity testing shall be
proposed by the registrant if the results of the chemical safety
assessment indicates the need to investigate further the effects of the
substance and/or relevant degradation products on sediment organisms.
The choice of the appropriate test(s) depends on the results of the
chemical safety assessment."
Formaldehyde has a low potential for adsorption or
bioaccumulation, exhibits a very high solubility in water, low
volatilization potential and is readily biodegradable. Distribution
modelling clearly shows that water will be the main target for
environmental distribution. Therefore, exposure of sediment organisms is
unlikely and testing towards sediment dwelling organisms not necessary.
Furthermore, the equilibrium partitioning method can be used for
assessing the hazard of sediment organisms.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority.
