Common NameZinc sulfide
ClassSmall Molecule
DescriptionZinc sulfide is a sulfide of zinc. It occurs naturally as the mineral sphalerite. Zinc sulfide is a semiconductor and is used as an infrared optical material and as phosphor in applications such as cathode ray tubes and glow in the dark products. Zinc is a metallic element with the atomic number 30. It is found in nature most often as the mineral sphalerite. Though excess zinc in harmful, in smaller amounts it is an essential element for life, as it is a cofactor for over 300 enzymes and is found in just as many transcription factors. (2, 3, 4)

Toxicity Profile
Route of ExposureInhalation (3) ; oral (3) ; dermal (3)
Mechanism of ToxicityAnaemia results from the excessive absorption of zinc suppressing copper and iron absorption, most likely through competitive binding of intestinal mucosal cells. Unbalanced levels of copper and zinc binding to Cu,Zn-superoxide dismutase has been linked to amyotrophic lateral sclerosis (ALS). Stomach acid dissolves metallic zinc to give corrosive zinc chloride, which can cause damage to the stomach lining. Metal fume fever is thought to be an immune response to inhaled zinc. (2, 3, 1)
MetabolismZinc can enter the body through the lungs, skin, and gastrointestinal tract. Intestinal absorption of zinc is controlled by zinc carrier protein CRIP. Zinc also binds to metallothioneins, which help prevent absorption of excess zinc. Zinc is widely distributed and found in all tissues and tissues fluids, concentrating in the liver, gastrointestinal tract, kidney, skin, lung, brain, heart, and pancreas. In the bloodstream zinc is found bound to carbonic anhydrase in erythrocytes, as well as bound to albumin, _2-macroglobulin, and amino acids in the the plasma. Albumin and amino acid bound zinc can diffuse across tissue membranes. Zinc is excreted in the urine and faeces. (3)
Toxicity ValuesLD50: >2000 mg/kg (Oral, Rat) (7) LD50: >2000 mg/kg (Dermal, Rat) (7) LC50: 5040 mg/m3 (Inhalation, Rat) (7)
Lethal DoseNot Available
Carcinogenicity (IARC Classification)No indication of carcinogenicity to humans (not listed by IARC).
Uses/SourcesZinc sulfide is a semiconductor and is used as an infrared optical material and as phosphor in applications such as cathode ray tubes and glow in the dark products. (4)
Minimum Risk LevelIntermediate Oral: 0.3 mg/kg/day (6) Chronic Oral: 0.3 mg/kg/day (6)
Health EffectsChronic exposure to zinc causes anemia, atazia, lethargy, and decreases the level of good cholesterol in the body. It is also believed to cause pancreatic and reproductive damage. (3)
SymptomsIngestion of large doses of zinc causes stomach cramps, nausea, and vomiting. Acute inhalation of large amounts of zinc causes metal fume fever, which is characterized by chills, fever, headache, weakness, dryness of the nose and throat, chest pain, and coughing. Dermal contact with zinc results in skin irritation. (3)
TreatmentZinc poisoning is treated symptomatically, often by administering fluids such as water or milk, or with gastric lavage. (3)
