SUPPLEMENTARY INFORMATION:
    Background: The NIOSH Manual of Analytical Methods (NMAM) was first 
published in 1974 and currently contains over 300 methods that can be 
used by occupational safety and health professionals to measure worker 
exposures to chemical and biological agents. In addition to the 
methods, the NMAM contains chapters that offer guidance on workplace 
air sampling, instrumentation, analytical protocols, and quality 
assurance. The draft chapter entitled, ``Analysis of Carbon Nanotubes 
and Nanofibers on Mixed Cellulose Ester Filters by Transmission 
Electron Microscopy,'' is proposed for addition to NMAM and provides 
standardized approaches for the analysis of carbon nanoparticles. These 
standardized approaches are meant to harmonize analytical techniques, 
enabling comparison of results between studies and fostering optimal 
data quality. NIOSH scientists published studies on the microanalysis 
of airborne carbonaceous nanomaterials, and this research has led to 
the procedures described in this chapter. The chapter provides detailed 
guidance on effective means to perform transmission electron 
microscopic analysis on carbon nanotubes and nanofibers that are 
sampled from occupational atmospheres. This draft chapter has 
previously undergone scientific peer review and is proposed for 
inclusion in the 5th edition of NMAM (www.cdc.gov/niosh/nmam).
    Information Needs: NIOSH is seeking public review and comment on 
this document from anyone with an interest in analysis of carbon 
nanoparticles.

Director, National Institute for Occupational Safety and Health,
