Ecological Information

Toxicity to Aquatic Life: Harmful, may accumulate in aquatic organisms
Persistence and Degradability: Inorganic, persists in environment with low degradability
Bioaccumulation: Potential for bioaccumulation, especially in aquatic systems
Mobility in Soil: Low to moderate, depends on pH and soil mineral content
Other Adverse Effects: May affect plant growth and soil microorganisms at high concentrations

Disposal Considerations

Disposal Methods: Treat as hazardous chemical waste, follow local and national guidelines
Container Disposal: Completely empty containers should be triple-rinsed, then managed as hazardous waste or recycled if allowed
Avoid Release: Never dispose of catalyst through drains or regular landfill
Recommended Practices: Use licensed hazardous waste disposal contractors; document all waste shipments
