Reference
Endpoint:
appearance / physical state / colour
Type of information:
experimental study
Adequacy of study:
key study
Study period:
26 September 2000 to 12 October 2000
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
other: see 'Remark'
Remarks:
The study was performed to a good standard and in line with GLP, with a good level of reporting sufficient to assess the reliability of the results. As the study was not specific to determine the appearance/physical state/colour for the substance, the study has been allocated a reliability score of 2 as the observations performed are considered to be an accurate reflection of the physical state and colour of the test material.
Qualifier:
no guideline followed
Principles of method if other than guideline:
Visual evaluations were made on the physical state and colour as the description of materials in a good quality acute oral toxicity study in rats. The toxicity study was performed in line with GLP and to a standardised guideline.
GLP compliance:
yes
Physical state at 20°C and 1013 hPa:
solid
Form:
powder
Colour:
grey
Substance type:
element
Conclusions:
The test material was described in an acute oral toxicity study as a grey powder.
Executive summary:

Visual evaluations were made on the physical state and colour as the description of materials in a good quality acute oral toxicity study in rats. The toxicity study was performed in line with GLP and to a standardised guideline. The test material was described as a grey powder.

solid

Additional information

The reference Blanchard (2000) included the description of the test material identity as part of a GLP compliant toxicological study performed in accordance with standardised guidelines. It is considered to be good descriptions of tantalum.
