Special
Remarks on Chronic Effects on Humans: Not
available.
Special
Remarks on other Toxic Effects on Humans:
Acute
Potential Health Effects: Skin: Causes mild skin irritation. There is no
significant skin irritation hazard for low level (usual) industrial handling or
exposure Eyes: Causes eye irritation. Inhalation: Causes respiratory tract and
mucous membrane irritation. There is no significant inhalation hazard for low
level (usual) industrial handling or exposure. Ingestion: Phosphates are toxic
because of their abillity to sequester calcium, but they are slowly and
incompletey absorbed when ingested, and seldom result in systemic effects.
Furthermore, acute potassium poisoning by mouth is rare because large single
doses usually induce vomiting and because in the absence of pre-existing kidney
damage, potassium is rapidly excreted. However, such effects have occured.
Symptoms may include gastrointestinal tract irritation (gastroenteritis) with
nausea, vomiting, abdominal discomfort, diarrhea. May affect behavior/central
nervous system(somnolence, listlessness, mental confusion,
convulsions),
metabolism (anorexia), cardiovascular system (fall of blood pressure, cardiac
arrythmias, heart block), kidneys (polyuria, polydipsia). May cause mineral
imbalance and affect osmotic pressure of body fluids. Other clinical signs and
symptoms of oral overdosage may include: paresthesias of the extremities,
weakness or heaviness of the legs, flaccid paralysis, cold skin, gray pallor.
