Exposure Assessment for Epidemiology Research: Use of Routine Industrial Monitoring Data

NorCal Education & Research Center | June 9, 2020 

Presented By: S. Katharine Hammond, PhD, CIH and Elizabeth M. Noth, PhD, MPH

Webinar Details

This presentation will discuss methods for using routine industrial monitoring data in epidemiology research. We will present how job exposure matrices are designed and used, and how changes to occupational controls affect long term average exposures. Learners will also review the implications of exposure misclassification in epidemiology studies.

Learning Objectives

At the completion of this activity, the learner will be able to:

  • Recognize the use of job exposure matrices (JEMs)

  • Describe the effect of exposure misclassification in epidemiology

  • Review the role on long term average exposures played by:

1) changing workplace processes,

2) installation of engineering controls, and

3) use of personal protective equipment


Dr. Katharine Hammond is Director of the Industrial Hygiene program and professor of environmental health sciences at the University of California, Berkeley School of Public Health. Her research career has focused on assessing exposure for occupational and environmental epidemiologic studies, e.g., metal working fluids, diesel exhaust, light metal manufacturing, solvents, welding, and chemical, physical and ergonomic exposures in the semiconductor industry. Her expertise in chemistry, industrial hygiene, risk assessment and public health enable her to develop innovative methods to characterize air contaminants and to create models to evaluate exposure for epidemiologic studies. Since 2000 she led the exposure assessment for several epidemiologic studies of air pollution in the CA Central Valley, she also studies indoor pollution from cook stoves in China, Nepal, Guatemala and Nigeria, and from secondhand smoke in the US and globally. She integrates her expertise in exposure assessment, chemistry, risk assessment and toxicology in her service on numerous state, national and international committees

Dr. Elizabeth Noth is a researcher in environmental and occupational exposure science, and is primarily focused on assessing air pollution exposure for epidemiologic studies.
 She is trained in exposure assessment, modeling and spatial analysis, with a focus on modeling short-term air pollution exposures. Her current research includes exposure assessment method development for environmental and occupational cohorts, evaluation of polycyclic aromatic exposures, and the role of biomass burning in ambient air pollution exposures.
