Description of key information

Additional information

No terrestrial studies are available for 2-amino-2-(hydroxymethyl)-1,3-propanediol (TRIS AMINO). In the environment, TRIS AMINO is expected to partition mainly into the water compartment, due to its high water solubility and low adsorption potential. The substance is also readily biodegradable, with very high degradation rates (ca. 100% after 10 days in OECD 301F), and would therefore be rapidly degraded, if present in soil pore water. Furthermore, all data available from aquatic toxicity tests indicate low toxicity. Based on these considerations, terrestrial testing is not proposed for this substance.
