Description of key information

Amides, C16-C18 (even), N,N'-ethylenebis does not exhibit bioaccumulation potential

Key value for chemical safety assessment

Additional information

The potential for bioconcentration of Amides, C16-C18 (even), N,N'-ethylenebis in a freshwater fish, Cyprinus carpio, was investigated in one study from the Japanese Ministry of International Trade and Industry (MITI, 1988). The study was conducted according to OECD Guideline No. 305: Bioconcentration: Flow-through Fish Test (1996). The fishes were exposed to two concentrations of the test substance (0.830 mg/L and 0.083 mg/L) for a period of 6 weeks, under flow-through water conditions. At the end of the test, estimated BCFs were <0.7 and <6.2 at the 0.830 and 0.083 mg/L concentrations respectively. Therefore, the test substance did not exhibit potential for bioconcentration in fish species. Additional information about this endpoint could be gathered through BCF calculation using BCFBAF (v3.00), a subroutine of theEPI Suite™ computer program. The BCF estimated value, based on whole body wet weight, was 5.048, and thus it supports the experimental result.

In conclusion, there is no indication of bioaccumulation potential of Amides, C16-C18 (even), N,N'-ethylenebis.
