Biodegradation in water and sediment: simulation tests
Administrative data
Link to relevant study record(s)
- Endpoint:
- biodegradation in water: simulation testing on ultimate degradation in surface water
- Remarks:
- Mesocosm studies
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- Full period not specified, but half-life determined
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- data from handbook or collection of data
- Justification for type of information:
- A review used to provide key information. Although primary references cited, these were not found.
Details of methods not provided.
Linked to photodegradation testing.
A number of bromonated phthalate fire retardants were assessed.
Some of these were esters which demonstrated initial transformation to the tetrabromophthalic acid and conisdered suitable surrogate to assess ultimate fate of the potassium salt. - Qualifier:
- equivalent or similar to guideline
- Guideline:
- EPA OPPTS 835.3180 (Sediment / Water Microcosm Biodegradation Test)
- Version / remarks:
- Method not provided in detail in review document
- Principles of method if other than guideline:
- A number of bromonated phthalate fire retardants were assessed.
Some of these were esters which demonstrated initial transformation to the tetrabromophthalic acid.
The work included assessment of the impact of sunlight. - GLP compliance:
- not specified
- Remarks:
- The work was performed by a research group and not a commercial test laboratory
- Radiolabelling:
- no
- Oxygen conditions:
- aerobic
- Inoculum or test system:
- natural water: freshwater
- Parameter followed for biodegradation estimation:
- test mat. analysis
- Remarks on result:
- other: Slow biological degradation reported
- Compartment:
- natural sediment
- DT50:
- < 50 d
- Type:
- not specified
- Temp.:
- 15 °C
- Remarks on result:
- other: Temperature considered 'standard' and is generally regarded as 15 C
- Transformation products:
- yes
- No.:
- #1
- Details on transformation products:
- A number of bromonated phthalate fire retardants were assessed.
Some of these were esters which demonstrated initial transformation to the tetrabromophthalic acid and conisdered suitable surrogate to assess ultimate fate of the potassium salt. The tetrabromophthalic acid itself lost the bromine in the presence of light. - Evaporation of parent compound:
- no
- Volatile metabolites:
- not measured
- Residues:
- yes
- Remarks:
- Phthalic acid remained
- Validity criteria fulfilled:
- not specified
- Conclusions:
- Although the details of testing are limited from the EPA review, it is concluded that the class of substance will show ultimate degradation with a combination of aerobic, anearobic and abiotic processes, with sunlight key to the process.
