International Chemical Safety Cards ZINC SULFATE HEPTAHYDRATE ICSC: 0349 I M P O R T A N T D A T A PHYSICAL STATE; APPEARANCE: GRANULES OR CRYSTALLINE POWDER. PHYSICAL DANGERS: CHEMICAL DANGERS: OCCUPATIONAL EXPOSURE LIMITS: TLV not established. MAK: 0.1 mg/m³ Peak limitation category: I(4) (Respirable fraction); 2 mg/m³ Peak limitation category: I(2) (Inhalable fraction); Pregnancy risk group: C (DFG 2009). ROUTES OF EXPOSURE: The substance can be absorbed into the body by inhalation of its aerosol and by ingestion. INHALATION RISK: Evaporation at 20°C is negligible; a harmful concentration of airborne particles can, however, be reached quickly when dispersed. EFFECTS OF SHORT-TERM EXPOSURE: The substance is irritating to the eyes , the skin and the respiratory tract . EFFECTS OF LONG-TERM OR REPEATED EXPOSURE: PHYSICAL PROPERTIES Melting point: 100°C Density: 1.97 g/cm³ Solubility in water, g/100 ml at 20°C: 54 ENVIRONMENTAL DATA The substance is very toxic to aquatic organisms.
