Description of key information
Fatty acids, tallow, zinc salts is assumed to (at least partly) dissociate to zinc ions and free fatty acids if taken up by organisms. The cellular content of zinc is regulated in organisms, and fatty acids are metabolised via well-known pathways. Fatty acids, tallow, zinc salts is thus not expected to bioaccumulate.
Key value for chemical safety assessment
Additional information
No experimental data are available on the terrestrial bioaccumulation of Fatty acids, tallow, zinc salts. Based on a read-across approach zinc bioaccumulation data and the fact that thECBe substance is readily biodegradable, bioaccumulation and biomagnification are not expected to be relevant for Fatty acids, tallow, zinc salts. For a comprehensive overview of the bioaccumulation of zinc or the lack thereof, see the hazard assessment of "Zinc" within the framework of Regulation (EC) No 1907/2006 reviewed below.
The EU Risk Assessment Report for Zinc distearate (CAS-No.: 557-05-1 & 91051-01-3) concludes that the bioaccumulation and biomagnification data available for zinc show that secondary poisoning is not relevant for zinc distearate and that the substance is not expected to bioaccumulate, as fatty acids will degrade by the ß oxidation pathway (ECB, 2008). This is also expected to apply to Fatty acids, tallow, zinc salts.
Furthermore bioaccumulation is not considered relevant for essential elements, such as zinc, because of the general presence of homeostatic control mechanisms. The data from a field food chain transfer study indicate that bioconcentration of zinc is indeed very low (Pascoe et al. 1996). It is in all cases also lower in contaminated soil, as compared to control soil.
