XRF Testing

Environmental XRF (X-ray Fluorescence) testing is a non-destructive analytical technique used to measure the elemental composition of various materials, particularly for environmental monitoring and contamination assessment.

Applications of Environmental XRF Testing

  1. Soil Testing

    • Detects heavy metals (Pb, As, Cd, Hg, Cr) and other contaminants.

    • Used in site assessments (e.g., industrial sites, agricultural land, mining areas).

  2. Water & Sediment Analysis

    • Filters or dried sediments are analyzed for toxic elements.

    • Helps in tracking pollution sources (e.g., industrial discharge).

  3. Airborne Particulate Matter

    • Filters from air samplers are tested for metals (e.g., Pb, Zn, Ni).

    • Monitors compliance with air quality regulations.

  4. Consumer Products & Waste

    • Screens for hazardous substances (e.g., RoHS compliance in electronics).

    • Analyzes recycled materials for contaminants.

  5. Industrial & Regulatory Compliance

    • EPA (Environmental Protection Agency) and OSHA guidelines often require XRF for hazardous site evaluations

XRF (X-ray Fluorescence) is a widely used method for detecting lead in paints, especially in older buildings where lead-based paint may pose health risks.

Why Test for Lead in Paint?

  • Health Risks: Lead exposure can cause neurological damage, especially in children.

  • Regulatory Compliance:

    • US EPA’s RRP Rule (Renovation, Repair, and Painting) requires lead testing before disturbing paint in homes built before 1978.

    • HUD Guidelines (U.S. Department of Housing) set lead-safe standards.

    • Global Regulations: Similar rules exist in the EU (REACH), Canada, and Australia.
