Administrative data

Endpoint:
acute toxicity: other routes
Type of information:
experimental study
Adequacy of study:
supporting study
Study period:
1946 or before
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
other: see 'Remark'
Remarks:
Study published in a peer-reviewed journal, according to scientific standards. Experimental details documented, but no data on acclimatization and housing. Results: Mortalities tabulated after 1 and 7 days, but no statistical determination of LD50. Performed 1946, before GLP and OECD guidelines were introduced. Sufficient numbers of animals investigated, but sex not stated.
