Materials and methods
- Principles of method if other than guideline:
- Non-standard. Degradation was invetigated in two acidic soils collected in northeastern Poland: a light loamy sand and a medium clay loam. 5 replicates each were tested. 34.42mg acetate were added to 100g soils together with 9 times the amount cellulose. The soil was incubated for 120days at 20°C and at 60% MWHC (33kPa).

- Transformation products:

- Details on results:
- The radioactivity was found as CO2 at approximately 2-6% on day 2, increasing to approx 20% on day 120. The rest of the AR was incorporated in humic acids, fulvic acids and humine. The residues found in the organic acids was approximately constant. The mineralisation amounts approximately 20% for both soils after 120 days (III) and the bound residues were arisen for approximately 80% (class IV).
Any other information on results incl. tables
Recovery rates for14C were 84 -99% in the light loamy sand and 74 -98% in the medium clay soil.
Mineralisation amounts were approximately 20% after 120 days and the non-extractable residues was approximately 80% after 120 days.
Applicant's summary and conclusion
- Conclusions:
- The primary degradation of acetate is fast, and complete incorporation into organic substances occured within 2 days. The main part was incorporated into humic or fulvic acids. In soil, acetic acid is metabolised fast within 2 days.
- Executive summary:
This study is non-GLP and no guideline. It lacks detail but provides an indication that acetic acid is degraded rapidly in soil.
