Administrative data
- Endpoint:
- acute toxicity: other routes
- Type of information:
- experimental study
- Adequacy of study:
- weight of evidence
- Study period:
- 1942
- Reliability:
- 4 (not assignable)
- Rationale for reliability incl. deficiencies:
- other: Although the study report in a peer-reviewed journal fulfilled scientific principles, some deviations (as expected) from OECD guideline developed 40 years later are apparent, mainly consisting of lack of experimental details.

Materials and methods
- Principles of method if other than guideline:
- 4 doses (0.1, 0.2, 0.4 and 0.8 g/kg bw sulfamic acid) were tested for acute oral toxicity by intraperitonal injection. Representative numbers of animals were used per dose group. Sulfamic acid was applied as 4% aqueous solution having a pH of 0.82, measured electrometrically.

Results and discussion
Effect levels
- Sex:
- male
- Dose descriptor:
- LD50
- Effect level:
- < 100 mg/kg bw
- Based on:
- test mat.
- Mortality:
- Mortality was observed in all dose groups applied being greater 50%.
100 mg/kg bw: 4/5 dead
200 mg/kg bw: 5/5 dead
400 mg/kg bw: 3/5 dead
800 mg/kg bw: 5/5 dead - Clinical signs:
- The author states "Sulfamic acid after intraperitoneal injection produced no toxic symptoms, although death occured on all dose levels 4 to 72 hours after adminstration."
- Body weight:
- 80 - 100 gram per rat, no effects on body weight development were reported
- Gross pathology:
- not performed in the acute study but in a chronic study, also reported in the article, histopathological examination failed to reveal and changes that could be ascribed to sulfamic acid exposure.
Applicant's summary and conclusion
- Conclusions:
- Sulfamic acid showed high systemic toxicity when applied intraperitoneal. When comparing to the effects seen in the oral study, described in the publication, the mortality seen in the i.p. study may be attributable to the very low pH (0.82) of the 4% aqueous solution injected.
- Executive summary:
In this published study acute intraperitoneal toxicity to rats was investigated up to a maximum dose of 800 mg/kg bw. Mortality > 50% occured at all doses (100, 200, 400 and 800 mg/kg bw). The animals produced no toxic symptoms, although death occured at all dose groups after 4 - 72 hours of exposure (i.p.). Therefore, no LD50 was reported. When comparing to the effects seen in the oral study, described in the same publication, the mortality seen in the i.p. study may be attributable to the very low pH (0.82) of the 4% aqueous solution injected. This is also supported by findings when ammonium sulfamate was applied (reported in the same study) which in 4% aqueous solution has a pH of 4.82 and only caused mortality at 800 mg/kg bw (6 out of 10 animals) when applied by intraperitoneal injection (no mortality at 100, 200 and 400 mg/kg bw).
