Description of key information
The substance is not readily biodegradable.
Key value for chemical safety assessment
- Biodegradation in water:
- not biodegradable
- Type of water:
- freshwater
Additional information
All substances in the category are inert, insoluble in water and octanol, and unreactive. They do not interact with proteins, have a high molecular weight and are insoluble. Thus, they will not be able to penetrate biological membranes. Therefore, the ready biodegradability of these substances is expected to be the same regardless of the slight structural differences between substances. The available experimental data can be used for read-across to all substances in this category. Ready biodegradability studies are available for the following two substances in the category: CAS 147-14-8 and CAS 12239-87-1.
A study on etrabenzo-5,10,15,20-diazaporphyrinephthalocyanine (CAS 147-14-8) was conducted similar to OECD guideline 301F (Manometric respirometry test). This study used domestic activated sludge as inoculum and was exposed to 107 mg/L test substance. Less than 1% of the substance was degraded after 28 d based on O2 consumption (BASF AG 1988, K2). Therefore, it is concluded that the substance is not readily biodegradable. The conclusion is supported by a GLP study conducted according to OECD test guideline 301C (NITE 1992, K2). A mixture of sewage, soil and natural water was used as inoculum and exposed to 100 mg/L test substance. No degradation was observed in the test condition after 14 d based on O2 consumption. Additionally, a GLP study conducted according to OECD TG 301C is available for the test substance CAS 12239-87-1. This study used non-adapted activated sludge as inoculum and was exposed to 100 mg/L test substance. After 28 days of exposure, 5% of the test substance was degraded based BOD analysis. No degradation of the test substance was observed based on gravimetric analysis (NITE 2003, K1). Therefore, it is concluded that the test substance CAS 12239-87-1 is not readily biodegradable.
Based on the results, it is concluded that all substances in the category are not readily biodegradable.
