What truly differentiates J.S. Held is our people — world-class talent driven by a common set of core values. Together, these shared values inspire a culture of integrity, excellence, teamwork, and service.
How much is too much? How clean is, well, clean? As a toxicologist in our Environmental, Health & Safety Practice, Nadia Moore answers these questions on a regular basis. “Everything in our world can be considered a poison, it’s how much we are exposed that determines if we have an adverse effect,” says Nadia.
Nadia assesses the health impacts from potential contaminants in workplace exposures, household exposures, and consumer products. She also determines acceptable occupational exposure and impurity levels in consumer products, then uses weight-of-evidence analysis of historical scientific data to gauge present-day conclusions.
“What truly sets Nadia apart is that she is such an integral team player and is also a valued leader in our practice. Her insight and ability to come together and solve problems to support our clients and her coworkers is incredible. She is the type of coworker and leader that makes you want to lean in and capture every word and nuance because it is so on-point and designed to be helpful and practical.”
In high school, Nadia developed a passion for science, biology in particular. She knew early on that she wanted to focus on applied sciences rather than the theoretical and was interested in using chemistry, biology, and genetics together to solve problems. This ultimately motivated her to earn her Bachelor of Science in Chemistry from Pacific Lutheran University in Tacoma, Washington.
Following college, Nadia worked at the Battelle Memorial Institute as a chemist, where she focused on supporting the inhalation laboratory in the study of toxicological assessments. She went on to achieve her PhD in Toxicology from the University of Washington in Seattle, after which she became a Study Director and the Toxicology Discipline Leader for National Toxicology Program Inhalation Studies at the Institute. Battelle later moved the inhalation testing facility to a different state, and Nadia transitioned to a consulting role at Veritox, Inc., where she worked for 5 years.
Nadia joined J.S. Held in 2019 as part of the Veritox, Inc. acquisition and is based in Redmond, Washington. As a subject matter expert in toxicology, molecular biology, and analytical chemistry, Nadia evaluates potential health effects from a wide range of chemical and physical agents (including asbestos, pesticides, solvents, vapors, particulate matter, metals, and microbial agents), diverse exposure scenarios (including environmental, occupational, and residential), and all routes of exposure—inhalation, oral (ingestion), and percutaneous (skin).
She routinely assesses whether exposure to a chemical or physical agent has caused (or can cause) an injury. This work includes, for example, blood alcohol concentrations, carbon monoxide exposures, and drinking water contaminants.
“My previous positions strengthened my knowledge in carcinogenicity testing, report writing, and my ability to work in and contribute to multidisciplinary teams. My passion for solving complex matters and providing innovative solutions to clients inspires me daily,” said Nadia.
Nadia enjoys getting outdoors as much as possible—biking, hiking, and skiing—but when the weather isn’t ideal, she opts for a group exercise class at the gym.
“Toxicology is all about the dose!”
Nadia has served on the board of the Pacific Northwest Association of Toxicologists for the last 6 years, moving through the presidential chain. She is also a part of Women in Toxicology of the Society of Toxicology and the Toxicology Committee of the American Industrial Hygiene Association, where she volunteers her time and engages students in the field of toxicology.
