sulfur di·ox·ide(SO2) (sŭlfŭr dī-oksīd)
Colorless, nonflammable gas with a strong, suffocating odor; a powerful reducing agent used to prevent oxidative deterioration of food and medicinal products.
a chemical element, atomic number 16, atomic weight 32.064, symbol S. See Table 6. Elemental sulfur is fed to animals to reduce their volume of feed intake, for example in a feedlot using self-feeders. It is also fed as an oldfashioned worm prophylaxis and coccidiostat.
Overfeeding of elemental sulfur causes enteritis characterized by black, evil smelling diarrhea. See also hydrogen sulfide poisoning.
a poisonous gas liberated by some industrial enterprises, e.g. copper smelting, from silage to which sodium metabisulfite has been added as a preservative and in oldfashioned treatments for mange. The gas causes irritation of the upper respiratory tract and pneumonia in severe cases. Commonly used as a meat preservative where it selectively destroys thiamin and has been incriminated as a cause of thiamin deficiency, particularly in dogs and cats.
small, soft to mineralized bodies in the pus of lesions of actinomycosis. Called also drusen.
skeletal and myocardial degeneration caused by the feeding of toxic levels of sulfur.
sulfur nutritional deficiency
ruminants may need supplemental inorganic sulfur if the bulk of their nitrogen is not in the form of protein but as urea or ammonium phosphate. A deficiency in these circumstances causes anorexia, weight loss, poor digestion and fall in milk yield.
a scabicide, antiparasitic, antifungal and keratolytic. Called also milk of sulfur.
a can of preserved meat contaminated by Clostridium nigrificans causing the formation of hydrogen sulfide, and black or purple staining of the inside of the can.
sulfur sublimatum, sublimed sulfur
a parasiticide and scabicide. Called also flowers of sulfur.
technetium coated sulfur colloid
used in scintigraphy of the liver and reticuloendothelial systems. Called also 99mTc sulfur colloid.
