Likely Routes of Exposure: Inhalation, skin and eye contact, ingestion
Acute Effects: Irritation to mucous membranes, eyes, and skin, gastrointestinal discomfort if ingested
Chronic Effects: Prolonged exposure to high concentrations may affect kidney and liver functions
Acute Toxicity: Data limited for chromium citrate; soluble trivalent chromium compounds show oral LD50 (rat) > 5000 mg/kg

Serious Eye Damage/Irritation: Causes eye irritation
Respiratory Sensitization: May cause coughing, throat or lung irritation
Carcinogenicity: Not listed as carcinogenic (IARC, NTP, OSHA) in trivalent form
Other Data: No effects on reproduction identified at recommended dietary use levels
Ecotoxicity: Chromium(III) generally shows moderate aquatic toxicity, more toxic to aquatic invertebrates at high concentrations
Persistence and Degradability: Chromium citrate is not readily biodegradable, tends to persist in soil and water
Bioaccumulative Potential: Bioaccumulation low for chromium(III) compounds, risk increases with accumulation in soil organisms
Mobility in Soil: Low solubility leads to moderate mobility, migration risk in acidic environments increases
Other Adverse Effects: Chromium(III) essential in trace amounts for some organisms but can disrupt ecological balance with overexposure
