- - Source of inoculum/activated sludge (e.g. location, sampling depth, contamination history, procedure): In March, June, September, and December, sludge was sampled at the following 10 places in Japan: 1. Fukogawa city sewage plant, 2. Fukashiba industry sewage plant, 3. Nakahama city sewage plant, 4. Ochiai city sewage plant, 5. Kitakami river, 6. Shinano river, 7. Yoshino river, 8. Lake Biwa, 9. Hiroshima bay, 10. Dookai bay; sampling: 1. City sewage: Returned sludge from sewage plants was taken. 2. Rivers, lake and sea: Surface water and surface soil which were in contact with atmosphere were collected.
- Method of cultivation: About 30 minutes after ceasing aeration to the sludge mixture, supernatant corresponding to about 1/3 of the whole volume was removed. Then the equal volume of dechlorinated water was added to the remaining portion and aerated again, followed by addition of synthetic sewage at a concentration of 0.1% (w/v). This procedure was repeated once every day. The culturing was carried out at 25 ± 2 °C. 5 L of the filtrate of the supernatant of old activated sludge was mixed with 500 mL of the filtrate of the supernatant of new sludge and cultured at pH 7.0 ± 1.0 under sufficient aeration using prefiltered open air. During the cultivation, appearance of the supernatant, precipitability, formation of flock, pH, dissolved oxygen concentration in the solution and temperature were checked and necessary adjustments were made, Microflora in the activated sludge was microscopically observed and sludge with no abnormal symptom was used for the test.

Description of key information
Poorly biodegradable.
Key value for chemical safety assessment
Additional information
The test substance belongs to the substance group of Phthalocyanines which resemble in their chemical structure. Due to the structure of the molecule and the extremely low water solubility of Phthalocyanines, biodegradation of the substances grouped to the category is not expected. However several tests on the biodegradability of single Phtalocyanines are available. All test results support the assumption that Phthalocyanines are only poorly biodegradable.
The biodegradability of CAS 147-14-8 was tested in a study following OECD guideline 301 F using domestic activated sludge as inoculum [BASF AG 1988]. After 28 days of inoculation a degradation rate of less than 1 % was determined. This result is supported by a second test accomplished according to OECD guideline 301 C [MITI 1992]. The study was performed with a mixture of sewage, soil and natural water as inoculum. The substance was degraded by 0 % after 14 days of incubation.
