Description of key information

No bioaccumulation expected.

Key value for chemical safety assessment

Additional information

Based on its structure and its physico-chemical properties a transportation of the substance through biological membranes can be excluded. Therefore, its bioaccumulative potential can be stated as very low and further testing is not proposed according to Annex IX, column 2, point 9.3.3.

This assumption is supported by a bioaccumulation study. The test set up was comparable to the specifications given in OECD guideline 305.Cyprinus carpiowas exposed to different concentrations of the substances for 6 weeks in a flow-through system. Fish were exposed to 0.1 mg/l and 0.01 mg/l of CAS 1328-53-6. BCFs of 4.8 and <2.1 were determined for the respective concentrations (MITI 1979)
