​This introductory-level course reviews toxicology fundamentals through the lens of occupational and environmental health and safety (OEHS) and includes examples and a detailed, interactive case study to expand on course concepts. This course will help learners feel more comfortable with key topics in toxicology so they can apply these newly gained skills to occupational health issues in their workplace, their developing consulting practice, or to their upcoming CIH Exam.

As an additional resource to learners, this course also includes the AIHA PDF publication Toxicology Principles for the Industrial Hygienist, 2nd edition.

Course Objectives

Upon completion, the learner will be able to:

  1. Describe the fundamental topics of occupational toxicology.
  2. Utilize resources to deduce and reason the exposure pathways of toxicants.
  3. Apply toxicology principles to evaluate an occupational toxicant.
  4. Recognize key risk information.
  5. Identify appropriate IH sampling to ensure workers' health and safety.
  6. Determine the fundamental topics needed for the toxicology portion of the BGC CIH exam.

Nadia Moore, PhD, DABT, ATS, ERT, CIH

Dr. Nadia Moore is certified in both industrial hygiene and in toxicology: she is a Certified Industrial Hygienist, a Diplomate of the American Board of Toxicology, a Fellow of the Academy of Toxicological Sciences, and is admitted to both the United Kingdom and EUROTOX registries as a European Registered Toxicologist. Dr. Moore is a Technical Fellow at J.S. Held, LLC, where her practice includes exposure and safety assessments for chemicals in consumer products and occupational environments. Her experience encompasses chemical and physical agents (including alcohol, cannabis/marijuana/THC, drugs, asbestos, metals, organic solvents/vapors, particulate matter, persistent organic chemicals, pesticides, solvents, talc, and microbial agents), diverse exposure scenarios, and all routes of exposure. Her practice also includes determination of whether exposure to a chemical or physical agent has caused an injury, determination of acceptable impurity levels in consumer products, and weight-of-evidence analysis of historical scientific data to gauge present-day conclusions. Dr. Moore has a PhD in toxicology with more than 25 years of multidisciplinary experience in toxicology, exposure science, regulatory compliance, molecular biology, and analytical chemistry. She has performed risk-based exposure and toxicology assessments for potential contaminants in workplaces, residential scenarios, and consumer products and has conducted short-term through 2-year carcinogenicity animal studies of inhaled vapors, aerosols, particulates, and complex mixtures.

Britt Weldon, PhD

Britt Weldon is a Toxicologist and Human Health Risk Assessor with Boeing's Environment, Health, and Safety group. Over the course of her career, Britt has held several technical positions measuring human exposures to various chemicals in the environment, evaluating mechanisms of toxicity, and assessing risk of adverse human health effects from chemical exposures in occupational settings and from consumer product use. She has been very involved in the development of risk communication strategies to the public, and has volunteered as a science communicator discussing human health risk assessment and toxicology concepts to the public. Britt earned her PhD in Toxicology from the Department of Environmental and Occupational Health Sciences at the University of Washington. Her PhD work involved evaluating human health effects from exposure to silver nanoparticles. She holds two Bachelor of Science degrees in Environmental Sciences, Dietetics, and Nutrition from the University of Vermont. She has authored several peer reviewed scientific journal articles, as well as a toxicology textbook chapter.

David G. Dodge, DABT, CIH

Mr. Dodge is a principal at Gradient with a versatile skill set in the human health risk sciences. He is board-certified in both toxicology and industrial hygiene. On behalf of clients in law, industry, and government, Mr. Dodge has characterized current and historical exposure to and health risks from a diverse array of chemical agents in products, workplaces, and the environment. Mr. Dodge received a Master’s of Science in Public Health from San Diego State University.

Angie Perez, PhD, CIH

Dr. Perez earned her doctorate in Toxicology from Oregon State University and conducted postdoctoral work at the University of California, San Francisco, in the Department of Pharmaceutical Chemistry. She has over 20 years of bench science and field experience in chemical exposure assessment, historical dose reconstruction, emergency response, and human health risk assessment. Her focal research-, field work, and testifying experience includes evaluation of exposures and potential health risks of airborne contaminants, evaluation of impairment from drugs and alcohol, and general causation assessment of health risks associated with perfluoroalkyl substances (PFAS). Dr. Perez and her family live in Portland, Oregon.
