Body
Weight Decrease (click

Chronic: Causes severe
skin irritation and burns. Ingestion or inhalation may be harmful
and possibly fatal depending on severity and length of over-exposure.
Chronic over- exposure may cause fluorosis. Product may be absorbed
through the skin and produce signs of fluorosis such as weight
loss, brittleness of bones, anemia, weakness and stiffness
of joints. Internal bleeding may develop. First aid procedures
should be followed even in cases of suspected contact.

-- Human Toxicity Excerpts:
SYMPTOMATOLOGY: A. Ingestion of soluble fluoride salts. 1. Salty
or soapy taste, salivation, nausea. Repeated small doses (as in
drinking water) may produce no other symptoms, but polyuria and
polydipsia have also been reported. 2. Large doses lead promptly
to burning or crampy abdominal pain, intense vomiting and diarrhea,
often with hematemesis and melena. Dehydration and thirst. 3.
Muscle weakness, tremors, and rarely transient
epileptiform convulsions, preceded or followed by progressive
central nervous depression (lethargy,
coma and respiratory arrest, even in the absence of circulatory
failure).
-- LD50 ranges of sodium, potassium, or ammonium fluorosilicates
administered intragastrically in rats and mice were 89-128 and
45-64 mg fluoride ion/kg, respectively. Severe cornea damage was
observed 3 hr after the administration of 50 mg of any of the
salts into rabbits' eyes. Min toxic dose (intragastric) of fluorosilicic
acid in rats was 8 mg/kg. Min toxic concn in 4 hr inhalation of
the salt aerosols were 7.4-9.6 mg/cu m; nontoxic concn was 0.8
mg/cu m. Main toxic effects were decreased
activities of cholinesterase and lactate
dehydrogenase in blood serum. The intragastric effects of the
fluorosilicates were similar to and additive with those of sodium
fluoride. [Rumyantser GI et al; Oig Sanit (11): 80-2 (1988)]
