Endpoint:
biological effects monitoring
Type of information:
experimental study
Adequacy of study:
supporting study
Study period:
From November 21, 1977 to April 5, 1978
Reliability:
2 (reliable with restrictions)

Materials and methods

Test guideline
Qualifier:
according to
Guideline:
other: JISA-9201, 9302, 9301 (Standard Japanese procedure for testing efficacy of wood preservative)
Deviations:
not specified
Principles of method if other than guideline:
Method is used to test efficacy of chemicals used as wood preservatives against specified test fungi. Standardized wood blocks, both weathered and unweathered, are treated (pressure impregnation) with a range of concentrations of the test chemical and incubated with the decay fungi for 90 days. Weight loss of the test block is used to assess the efficacy of the chemical preservative.
GLP compliance:
not specified
Type of study / information:
Eficacy of 2,4,6-tribromophenol against decay fungi as a wood preservative.

Test material

Name:
Unnamed
Type:
Constituent
Details on test material:
Name of test chemical is given as TBP technical and formulations - TBP-Na salt, oil and EC.

Results and discussion

Any other information on results incl. tables

The concentrations of 2,4,6-TBP reported (e.g. efficacy against decay fungi at concentrations down to 0.5% dilution, which is pressure impregnated into the wood) are applicable only to wood preservation.

Applicant's summary and conclusion

Conclusions:
Report consists of very short summary and data tables, with standard methods attached. Appears to have followed the attached standard methods (Japanese methods for testing efficacy of wood preservatives, JISA-9201, 9302, and 9301). No analytical details provided. The concentrations of 2,4,6-TBP reported (e.g. efficacy against decay fungi at concentrations down to 0.5% dilution, which is pressure impregnated into the wood) are applicable only to wood preservation. However, it can be concluded from study that 2,4,6-TBP is toxic to the tested decay fungi at particular concentrations.
