Sicherheit & Vorschriften
| Minimum Risk Level | Intermediate Oral: 0.3 mg/kg/day (L134)
Chronic Oral: 0.3 mg/kg/day (L134) |
|---|
| Treatment | Zinc poisoning is treated symptomatically, often by administering fluids such as water or milk, or with gastric lavage. (L49) |
|---|
| Gesundheitliche Auswirkungen | Chronic exposure to zinc causes anemia, atazia, lethargy, and decreases the level of HDL (good) cholesterol in the body. It is also believed to cause pancreatic and reproductive damages. Unbalanced levels of copper and zinc binding to Cu,Zn-superoxide dismutase have been linked to amyotrophic lateral sclerosis (ALS). (L49) |
|---|
| Expositionspfade | Oral (L49)inhalation (L49)dermal (113) |
|---|
| Toxizitätsübersicht | Excessive zinc intake alters copper and iron absorption, most likely through competitive binding in intestinal mucosal cells. Stomach acid dissolves metallic zinc, producing zinc chloride, which is a corrosive product damaging the stomach lining. Metal fume fever is thought to be an immune response to inhaled zinc. (L48, L49, A49) |
|---|
| Signs and Symptoms | 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. (L49) |
|---|
| Carcinogen Classification | No indication of carcinogenicity to humans (not listed by IARC). |
