Materials and methods
Test guideline
- Qualifier:
- no guideline required
- Deviations:
- not applicable
- Principles of method if other than guideline:
- For the estimation/calculation the percentages by weight and the mean percentages of branching (given in Attachment 8, Table 1a and b) have been used to determine a composition of a typical sample of the substance 'Naphtha (Fischer-Tropsch), light, C4-C10 - branched and linear'. Branched and linear aliphatic components are present in a ratio that can vary between the approximate limits of 20:80 and 80:20. This compositions have been used as the basis for modelling biodegradability.
- GLP compliance:
- no

- not applicable (estimated by calculation)

Results and discussion
% Degradation
- Parameter:
- other: calculation
- Value:
- > 60
- Sampling time:
- 28 d
- Remarks on result:
- other: linear:branched component ratio of 20:80--> 19.6% of test substance is predicted to be readily biodegradable and passing the 10-day window ; 77.6% of the test substance is predicted to be readily biodegradable but not passing the 10-day window
- Details on results:
- The biodegradability of the chemical components of the substance has been predicted in accordance with the methods described by Peter Fisk Associates (2006). The results of applying these methods to a typical composition (see Attachment 8, Section 3 and Tables 1a, b and 2) show that with a linear:branched component ratio of 20:80, 19.6% of its mass would be considered readily biodegradable, passing the 10-day window (RB10), 77.6% would be readily biodegradable not passing the 10-day window (RBN) and 0.8% would be inherently biodegradable (INH).
Applicant's summary and conclusion
- Validity criteria fulfilled:
- not applicable
- Remarks:
- estimated by calculation
- Interpretation of results:
- readily biodegradable, but failing 10-day window
- Conclusions:
- A reasonable conclusion that can be drawn is that 'Kerosine (Fischer-Tropsch), full range, C8-16 - branched and linear' (with a linear:branched
component ratio of 20:80) should be considered to be readily biodegradable, but failing the 10-day window criterion. The substance would therefore be classed 'readily biodegradable, but failing 10-day window'.
Test data found in the literature for 'Distillates (petroleum), hydrotreated light' (CAS No. 64742-47-8), which was reported in the environmental
hazard property summary review by Peter Fisk Associates (2006) support this conclusion: 70% biodegradation in 28 days, but the 10-day window
criterion was not met. The test that was conducted in accordance with OECD Guideline 301F (Manometric respirometry) has however been
reviewed under the OECD SIDS programme for HPV substances (OECD SIDS, 2003) and achieved a reliability rating of 1 (the highest reliability). It
should be noted that the original study report has not been reviewed.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
