Routes of Exposure: Inhalation, skin contact, eye contact, ingestion
Symptoms: Gastrointestinal upset, nausea, mild skin or eye irritation, no chronic toxicity at recommended exposure limits
Chronic Toxicity: No evidence of mutagenicity, carcinogenicity, or reproductive toxicity based on available data
Sensitization: Not known to sensitize skin or respiratory tract
Other Effects: Overexposure to zinc compounds may cause zinc fever (metal fume fever) in rare cases
Aquatic Toxicity: Toxic to aquatic life in high concentrations, zinc ions pose greatest risk
Persistence and Degradability: Methionine component is biodegradable, zinc persists in the environment, may bioaccumulate in aquatic organisms
Bioaccumulation Potential: Zinc can gradually accumulate in soil and water systems, persistence hazard warrants careful management
