Control of Workplace Exposures Using Personal Monitoring Badges

This study demonstrates how the theory in the NIOSH Occupational Exposure Sampling Strategy Manual and the quality control principle that cost-effective, convenient test methods support increased testing have been combined to improve statistical control of worker exposures over 30 years of practice. More frequent testing using personal monitoring badges has helped to create a situation where OEL overexposures are rare today compared to the 1970's and 1980's.

Uptake of the Widest Range of Hazardous Volatile Organic Analytes Using an Inorganic Mesoporous Sorbent
The presentation will describe the superior performance of an inorganic mesoporous sampling media, called OSU-6, compared to traditional activated carbon sorbents used to capture organic solvents. XploSafe manufactures and markets OSU-6, which has the highest surface area, pore-volume, thermal stability, and resistance to hydrolysis of this type of material. The unique properties of mesoporous sorbent stem from its exceptionally high surface area and distinctive cylindrical pores. XploSafe researchers have demonstrated theoretically and experimentally that the curved surface of the cylinders binds organic compounds due to strong van der Waals forces. This, in combination with the presence of silanol groups, make the mesoporous media an excellent sorbent for a wide range of nonpolar and polar organic molecules. The surfaces of the mesoporous media could be derivatized to add functional groups to enhance the sorption of compounds that may not bind strongly to the native surfaces. The present work will include XploSafe's recent efforts in applying this versatile sorbent in the passive sampling of a wide class of toxic chemicals with both high and low vapor pressures.
