| Gefahrenübersicht | An eye irritant[Klenzoid MSDS] See Zinc. See Disodium pyrophosphate. |
| Hazard Classes and Categories | Aquatic Acute 1 (95.7%) |
| Expositionsschutz und Persönliche Schutzausrüstung | 0.1 [mg/m3] (respirable fraction), 2 mg/m3 (inhalable fraction) for Zn inorg. cmpnds[German Research Foundation (DFG)] |
| 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 good cholesterol in the body. It is also believed to cause pancreatic and reproductive damage. (L49) |
| Expositionspfade | Inhalation (L49)oral (L49)dermal (L49) |
| Toxizitätsübersicht | 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.
