Common NameUranyl zinc acetate
ClassSmall Molecule
DescriptionUranyl zinc acetate is a chemical compound of uranium and zinc. Uranium is a chemical element that has the symbol U and atomic number 92. It is a normal part of rocks, soil, air, and water, and occurs in nature in the form of minerals. 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. (4, 5, 8, 9)

Toxicity Profile
Route of ExposureOral (5) ; inhalation (5) ; dermal (5)
Mechanism of ToxicityUranium is combined with either bicarbonate or a plasma protein in the blood but once in the kidney, it is released and forms complexes with phosphate ligands and proteins in the tubular wall, causing damage. Uranium may also inhibit both sodium transport-dependent and independent ATP utilization and mitochondrial oxidative phosphorylation in the renal proximal tubule. Uranium causes respiratory diseases by damaging alveolar epithelium type II cells in the lungs. Uranium induces c-Jun N-terminal kinase (JNK) and p38 mitogen-activated protein kinase (p38 MAPK) activation, which in turn induces tumor necrosis factor alpha (TNF-alpha) secretion and generates and inflammatory response in the lungs. Studies have shown that the more soluble the uranium salt, the more toxic it is. Ionizing radiation produced by uranium damages the DNA, resulting in gene mutations and chromosomal aberrations. This can both both initiate and promote carcinogenesis, and interfere with reproduction and development. Anaemia 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. (4, 5, 1, 9, 2)
MetabolismUranium is absorbed in low amounts via oral, inhalation, and dermal routes. Uranium in body fluids generally exists as the uranyl ion (UO2)2+ complexed with anions, such as citrate and bicarbonate, or plasma proteins. Uranium preferentially distributes to bone, liver, and kidney. The large majority of uranium that enters the body is not absorbed and is eliminated from the body via the urine and faeces. Zinc 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. (5, 8)

Lethal DoseNot Available
Carcinogenicity (IARC Classification)Uranium: Group 1, carcinogenic to humans (10)
Uses/SourcesNot Available
Minimum Risk LevelIntermediate Inhalation: 0.0004 mg/m3 (Soluble uranium salts) (7) Chronic Inhalation: 0.0003 mg/m3 (Soluble uranium salts) (7) Intermediate Oral: 0.002 mg/kg/day (Soluble uranium salts) (7) Intermediate Inhalation: 0.008 mg/m3 (Insoluble uranium compounds) (7) Intermediate Oral: 0.3 mg/kg/day (Zinc) (7) Chronic Oral: 0.3 mg/kg/day (Zinc) (7)
Health EffectsUranium primarily damages the kidney, but may also damage the lungs, central nervous system, and immune system. Uranium's radioactivity is believed to damage the DNA, resulting in carcinogenic effects and reproductive and developmental damage. Chronic 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. (5, 8, 9)
SymptomsIngestion of uranium may cause vomiting and diarrhea. Ingestion 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. (5, 8)
TreatmentZinc poisoning is treated symptomatically, often by administering fluids such as water or milk, or with gastric lavage. (5)
