Additional information

The bioaccumulation potential of Dodecane-12-lactam was investigated experimentally in Cyprinus carpius (CITI 1992) and calculated with EPIWIN.

The experimentally derived bioconcentration factors at two concentration levels were 0.8 - 1.2 (0.5 mg/l) and <2.6 (0.05 mg/l) respectively. The calculated BCF was 35.35 (BCFWIN v2.14).

Conclusion on classification

The substance is not subject to labelling provisions as to environmental hazard by Directive 67/548/EWG and under regulation 1272/2008.
