Chronic Effects on Humans
Special Remarks on other Acute Potential Health Effects:
Toxic Effects on Humans Skin: May cause skin irritation.
Eyes: May cause eye irritation.
Inhalation: May cause respiratory tract irritation.
Ingestion: May cause gastrointestinal tract irritation. Magnesium salts are absorbed very slowly. Oral
administration causes nothing more than purging and is not likely to produce serious toxic effects. However,
some compounds may cause hypermagnesemia in individuals with serverely impaired renal function which may
affect behavior/central nervous system and respiratory system. Symptoms of hypermagnesinia poisoning may
include central nervous system depression, lethargy, coma, circulatory failure, and respiratory arrest due to
neuromuscular blockade(respiratory paralysis).
The toxicological properties of this substance have not been fully investigated.
