Additional information

Ecotoxicological information:

In ecotoxicological studies ZINN(II)-RICINOLEAT proved to be readily biodegradable, the lowest obtained acute EC/LC50 value is the 48-h-EC50 of 5.14 mg/L for daphnia magna.

Short-term toxicity to aquatic organisms:

·       Fish: LC50 (96 h) = > 100 mg/L (nominal, WAF) for Cyprinus carpio (OECD 203)

·       Invertebrates: EC50 (48h) = > 5.14 mg/L (measured, WAF) for Daphnia magna (OECD 202)

·       Algae and cyanobacteria: ErC50 (0-72 h) = > 100 mg/L (nominal, WAF) for Pseudokirchneriella subcapitata (OECD 201)

 

Biodegradation: 

Biodegradation in water: readily biodegradable (OECD 301F) (10-d-w maintained, 86% biodegradation after 28 d)

 

Bioaccumulation:  

The log Kow was determined to be 4.8 at pH 3, therefore ZINN(II)-RICINOLEAT will have a potential for bioaccumulation in aquatic organisms. However in contact with air or water containing oxygen, the Tin(II)-compound will be oxidised to the Tin(IV)-compound within hours-days forming insoluble SnO2. The inorganic SnO2 is not expected to bioaccumulate.

The log Koc of the test substance in non-ionised form was determined to be log Koc = 3.3 (Koc=2000) and for the ionized form log Koc = 3.2 (Koc=1600). Taking into account the classification scheme of Blume & Ahlsdorf (1993), a high sorption onto soil organic matter has to be expected. However in contact with air or water containing oxygen, the Tin(II)-compound will be oxidised to the Tin(IV)-compound within hours-days forming insoluble SnO2.

Conclusion on classification

Lowest EC50 value relevant for classification and labelling: 

              Daphnia magna: 48h EC50 = 5.14 mg/L (measured)

 

Acute aquatic toxicity:

Acute EC50 values > 1mg/L, therefore no classification "acute aquatic toxicity" is required.

 

Chronic aquatic toxicity:

Based on the lowest EC50 of 5.14 mg/L (measured) for Daphnia magna and according to the threshold values for C&L (48h EC50 (Crustacea) >1 to ≤ 10 mg/L) Category Chronic 2 has to be assigned.

The substance is readily biodegradable, however the log Kow is ≥ 4 (4.8).
