Physical Description | Anhydrous zinc sulfate is a colorless crystalline solid. Zinc sulfate is also obtained as a hexahydrate, ZnSO4.6H2O, and as a heptahydrate ZnSO4.7H2O. All forms are soluble in water. All are noncombustible. The primary hazard is the threat posed to the environment. Immediate steps should be taken to limit its spread to the environment. It is used in the production of rayon, as a feed supplement, and as a fertilizer ingredient.

Toxicity

EPA Ecotoxicity

Pesticide Ecotoxicity Data from EPA: 2

ICSC Environmental Data

The substance is very toxic to aquatic organisms. It is strongly advised not to let the chemical enter into the environment.

Probable Routes of Human Exposure

NIOSH (NOES Survey 1981-1983) has statistically estimated that 2,849 workers (705 of these are female) are potentially exposed to zinc sulfate heptahydrate in the US(1). /Zinc sulfate heptahydrate/

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)

Treatment

Zinc poisoning is treated symptomatically, often by administering fluids such as water or milk, or with gastric lavage. (L49)

Toxicity Data

LD50: 57 mg/kg (Oral, Mouse) (T13) LD50: 71.7 mg/kg (Intraperitoneal, Mouse) (T13) LD50: 40 mg/kg (Intravenous, Rat) (T81)

Health Effects

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)

Exposure Routes

Inhalation (L49); oral (L49); dermal (L49)

Toxicity Summary

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. (L48, L49, A49)

Minimum Risk Level

Intermediate Oral: 0.3 mg/kg/day (L134) Chronic Oral: 0.3 mg/kg/day (L134)

Carcinogen Classification

No indication of carcinogenicity to humans (not listed by IARC).

Evidence for Carcinogenicity

CLASSIFICATION: D; not classifiable as to human carcinogenicity. BASIS FOR CLASSIFICATION: Based on inadequate evidence in humans and animals. HUMAN CARCINOGENICITY DATA: Inadequate. ANIMAL CARCINOGENICITY DATA: Inadequate. /Zinc and compounds/
