Description of key information

According to the measured BCF the substance does not significantly accumulate in organisms.

Key value for chemical safety assessment

BCF (aquatic species):

Additional information

To determine the bioaccumulative potential of TEA to aquatic organisms, a study conducted according to the OECD test guideline 305 was performed. Cyprinus carpio was used as test species. The determined BCF in this study was < 3.9 at a concentration of 0.25 mg/l whereas at a concentration of 2.5 mg/l a BCF < 0.4 was measured (MITI 1992).

This experimental result is supported estimated BCFs from a variety of models. The highest BCF was calculated to be 3. In all cases of the following models, TEA was within the applicability domain:

- EPI Suite v4.11, BCFBAF v3.01: BCF = 3

- US EPA T.E.S.T. v4.1: BCF = 0.46

- VEGA Read-across v1.0.2: BCF = 0.68

- VEGA Meylan v1.0.2: BCF = 3

- VEGA CAESAR v 2.1.13: BCF = 3

- OASIS Catalogic v5.11.9.13 BCF base-line model v02.07: BCF = 9.2 without mitigating factors; BCF = 2.4 taking into account mitigating factors like water solubility, molecular size and metabolism. Water solubility had the highest effect on reducing the bioaccumulation potential.
