Description of key information

Does not accumulate in organisms. 

Key value for chemical safety assessment

Additional information

The solubility of Phthalocyanines in octanol and in water is extremely low. Therefore bioaccumulation of the substance is not probable.

This assumption is supported of two bioaccumulation studies available for CAS 147-14-8 and CAS 1328-53-6 respectively. The test set up was comparable to the specifications given in OECD guideline 305. Cyprinus carpio was exposed to different concentrations of the substances for 6 weeks in a flow-through system. A BCF < 3.6 was determined for a concentration of 0.06 mg/l CAS 147-14-8. Whereas a concentration of 0.6 mg/l resulted in a BCF of <0.33 (MITI 1979). Comparable results were obtained for CAS 1328-53-6. 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).
