- Route of exposure:
- oral

- intentional
- Exposure assessment:
- estimated
Results and discussion
- Clinical signs:
- Immediate vomiting, then facial numbness, diarrhoea, diaphoresis, muscle spasms, weakness, abdominal pain, dyspnoea, shallow breathing, and cramps of the palms, feet, and legs. Tachycardia and tachypnea were observed. After 12 hours, generalized weakness and enlargement of the liver continued.
Any other information on results incl. tables
Treatment with calcium compounds (calcium carbonate initially; calcium lactogluconate for ten days after life-threatening symptoms had diminished) resulted in recovery within 21 days. Fluoride levels in serum and urine were 5.130 and 235.60 mg/dm3, respectively, on day 2 of hospitalization. Treatment with calcium compounds (calcium carbonate and calcium lactogluconate) immediately returned levels to normal. The following day, the levels dropped to 0.399 and 15.39 mg/dm3, respectively; by day 20, the levels were 0.067 and 0.87 mg/dm3, respectively.
Applicant's summary and conclusion
- Conclusions:
- The signs and symptoms of toxicity in this poisoning case are consistent with fluoride poisoning.
- Executive summary:
A case report of a suicide attempt is reported.
A female chemical plant worker (32 years old) who ingested three teaspoons of sodium hexafluorosilicate immediately began vomiting, and then experienced facial numbness, diarrhea, diaphoresis, muscle spasms, weakness, abdominal pain, dyspnea, shallow breathing, and cramps of the palms, feet, and legs. Tachycardia and tachypnea were observed. After 12 hours, generalized weakness and enlargement of the liver continued. Treatment with calcium compounds (calcium carbonate initially; calcium lactogluconate for ten days after life-threatening symptoms had diminished) resulted in recovery within 21 days. Fluoride levels in serum and urine were markedly elevated; no effect were apparent on the level of fluoride in nails. The signs and symptoms of toxicity in this poisoning case are consistent with fluoride poisoning.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation).
