Health Effects: Nuisance particulate (HE19); Chronic toxicity---Skin sensitization, permanent eye damage (HE3)

Affected Organs: Skin, respiratory system

Notes:

  1. Ingestion of a large amount of elemental sulfur may result in production of hydrogen sulfide by intestinal bacteria, as described for cattle and sheep, which may have different toxic effects on them depending upon whether it is inhaled by eructation (belching) of the gas (collapse, sudden death) or absorbed via the intestinal tract (sulfhemoglobinemia, dehydration from diarrhea, apparent blindness).
  2. A method for estimating inorganic sulfur dietary intake in humans, based upon measurement of 24-hour urinary excretion of nitrogen and sulfate, was published.
