Adsorption / desorption
Administrative data
- Endpoint:
- adsorption / desorption, other
- Data waiving:
- study technically not feasible
- Justification for data waiving:
- the study does not need to be conducted because the substance and its relevant degradation products decompose rapidly
- other:
- Justification for type of information:
- Chromium III salts form naturally in biological systems and will ultimately mineralise. Formic acid is readily biodegradable.
The behaviour in soil of chromium will depend on the counter ions present. This cannot be predicted from laboratory screening studies.
Chromium(III) in soil is mostly present as insoluble carbonate and oxide of chromium(III); therefore, it will not be mobile in soil. The solubility of chromium(III) in soil and its mobility may increase due to the formation of soluble complexes with organic matter in soil, with a lower soil pH potentially facilitating complexation (Avudainayagam et al. 2003).
Chromium has a low mobility for translocation from roots to the aboveground parts of plants (Calder 1988; Cary 1982; EPA 1984a, 1985a; King 1988; Stackhouse and Benson 1989).
Cross-reference
- Reason / purpose for cross-reference:
- data waiving: supporting information
Reference
- Endpoint:
- biodegradation in water: ready biodegradability
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 28 days
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- data from handbook or collection of data
- Justification for type of information:
- Taken from peer reviewed publication covering formic acid; not all method details were reported, but sufficient data to confirm outcome
Substance is slightly acidic, suggesting excess of formic acid, but solubility was greatly enhanced at lower pH.
Under environmental pH (buffered pH 7) there was still significant solubility (dissociation) of the substance
Result of dissociation concentrate testing indicate full dissociation at all biological and environmental pH - Qualifier:
- equivalent or similar to guideline
- Guideline:
- OECD Guideline 301 C (Ready Biodegradability: Modified MITI Test (I))
- Principles of method if other than guideline:
- Full methodology not provided in reference
- GLP compliance:
- not specified
- Specific details on test material used for the study:
- Assessment based on formic acid
- Oxygen conditions:
- aerobic
- Inoculum or test system:
- activated sludge (adaptation not specified)
- Duration of test (contact time):
- 28 d
- Based on:
- not specified
- Remarks:
- Details not provided
- Parameter followed for biodegradation estimation:
- CO2 evolution
- Reference substance:
- other: Not specified
- Key result
- Parameter:
- % degradation (CO2 evolution)
- Value:
- > 99
- Sampling time:
- 28 d
- Details on results:
- Rapidly biodegradable
- Validity criteria fulfilled:
- not specified
- Interpretation of results:
- readily biodegradable
- Conclusions:
- The handbook reports rapid biodegradation.
Formic acid and its salts occur in nature in metabolic processes.
Sodium and potasium formate are used as biodegradable de-icing materials for use in airports and on roads. - Executive summary:
Chromium is not biogradable, so assessment is based on formic acid
Substance is slightly acidic, suggesting excess of formic acid, but solubility was greatly enhanced at lower pH.
Under environmental pH (buffered pH 7) there was still significant solubility (dissociation) of the substance
Result of dissociation concentrate testing indicate full dissociation at all biological and environmental pH
