DELAMINATION AND XRF ANALYSIS OF NIST LEAD IN PAINT FILM STANDARDS
ROGERS, K. R. AND J. ABACHERLI. DELAMINATION AND XRF ANALYSIS OF NIST LEAD IN PAINT FILM STANDARDS. Presented at Lead Paint Test Kit Workshop, Research Triangle Park, NC, October 19 - 20, 2006.
The overall objective of this task is to develop scientifically sound sampling and bioanalytical approaches for screening and monitoring of hazardous wastes. These techniques are expected to provide the Agency with improved screening and field portable methods to characterize, reduce, and control risk to human health and the environment. Specific objectives will include development and characterization of the following concepts:
SPMDs for passive accumulation of TICs
Bioassays for toxic and genotoxic compounds
MIPs for volatile and semivolatile toxic organics
Rapid screening assays using the previously listed components.
The objectives of this protocol were to remove the laminate coating from lead paint film standards acquired from NIST by means of surface heating. The average XRF value did not change after removal of the polymer coating suggesting that this protocol is satisfactory for rendering the NIST-XRF standard paint films acceptable for use with the chemically-based lead test kits.
