• Description:
  Background: Exposure to nanoparticles is an increasing health concern. Current exposure assessment methods for nanoparticles are expensive. Sampling for metals may be obscured by metallic content of the sampling media. Current Nanoparticle Respiratory Deposition (NRD) sampler uses nylon mesh containing metals. Objective: To broaden the applicability of an innovative nanoparticle respiratory deposition (NRD) sampler by identifying alternate sampling media to collect and quantify multiple metals. ... Conclusion: Different sampling media (foams, mesh screens, cellulose, and granular beds) can be designed to collect particles with efficiencies matching human lung deposition for particles smaller than 300 nm. Low metals content of commercially available sampling media, such as cellulose and some foams, indicate that they would be appropriate for sampling and analysis of airborne metals using the NRD sampler. SEM imaging can be used to quantify sampling media parameters such as fiber diameter and pore size for development of a theoretical collection efficiency model. [Description provided by NIOSH]
