SECTION 11. TOXICOLOGICAL INFORMATION
CARCINOGENIC EFFECTS: No components of this product present at levels greater than or equal to 0.1% is identified a carcinogen.
MUTAGENIC EFFECTS: Not available
TETRATOGENIC EFFECTS: Not available
RTECS: No data
ACUTE AND CHRONIC TOXICITY: Dysprosium Compounds: Soluble dysprosium salts, such as dysprosium chloride and dysprosium
nitrate, are mildly toxic when ingested. The insoluble salts, however, are non-toxic. Based on the toxicity of dysprosium chloride to
mice, it is estimated that the ingestion of 500 gm. or more could be fatal to a human. Boron Compounds: Only a few human studies
have been conducted to assess health effects associated with exposure to boron compounds. The available data show that exposure
is associated with short-term irritant effects on the upper respiratory tract, nasopharynx, and eye. These effects, however, appear to be
short-term and reversible. The sole long-term (7-year) follow-up study failed to identify any long-term health effects. No studies have
been identified that assess reproductive outcomes. From 782 cases of boric acid ingestion, all except two cases were acute ingestions.
88.3% were asymptomatic. Among the remaining 11.7%, frequent symptoms included vomiting, abdominal pain, and diarrhea. Among
the children less than 6 years of age, 21 ingested more than the estimated lethal dose of 15 gm all without severe manifestations of
toxicity or life-threating symptoms. In this series only minimal toxicity was seen at serum levels or less than or equal to 640 mg/ml.
To the best of our knowledge the toxicological effects of this compound have not been fully investigated.
