Description of key information
The substance is not readily biodegradable (according to OECD criteria).
Key value for chemical safety assessment
Additional information
No experimental data are available. Read-across was performed in order to assess the acute toxicity of Ammonium [trisulphamoyl-29H,31H-phthalocyaninesulphonato(3-)-N29,N30,N31,N32]cuprat e(1-) (CAS 94534-99-3) to fish. The substance belongs to the chemical category of Phthalocyanines whose category members resemble in their chemical structure as well as in their physico-chemical properties. Thus, read-across data from analogous substances of the phthalocyanine category were used to cover this endpoint.
The biodegradation potential of Cuprate(1-), [tris(aminosulfonyl)-29H,31Hphthalocyaninesulfonato(3-)-N29,N30,N31,N32]-, ammonium (Fastusol, CAS 94534-99-3) was assessed based on read-across to the data available for the structural analogues Direct Blue 199_Na (CAS 90295-11-7) and Heliogen Blue 6920 (CAS 147-14-8):
- The biodegradability of Heliogen Blue (CAS 147-14-8) was tested in a study following EU Directive 79/831/EEC Annex V, part C (comparable to 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, based on O2 consumption, indicating this source substance to be poorly biodegradable (not readily biodegradable according to OECD criteria).
- The biodegradability of Direct Blue 199_Na (CAS 90295 -11 -7) was tested in a study following OECD guideline 302 B using domestic activated sludge as inoculum (Archroma, 2006). After 28 days of inoculation a degradation rate of 5 % was determined, based on DOC removal, indicating this source substance to be poorly eliminated from water (not readily biodegradable according to OECD criteria).
Conclusion:
Based on the available read-across data from the structurally analogous substances Heliogen Blue (CAS 147-14-8) and Direct Blue 199_Na (CAS 90295 -11 -7) the target substance Cuprate(1-), [tris(aminosulfonyl)-29H,31Hphthalocyaninesulfonato(3-)-N29,N30,N31,N32]-, ammonium (Fastusol, CAS 94534-99-3) is assessed to be not readily biodegradable (according to OECD criteria).
Due to the molecular structure and the extremely low water solubility of Phthalocyanines, biodegradation of substances grouped to this category is additionally not expected in general.
