Ms. Dahlberg is an environmental health scientist who specializes in health risk assessment, practical toxicology, and regulatory science. She has extensive experience with conducting systematic literature reviews and meta-analyses, evaluating and assessing biases in epidemiologic studies, data visualization including the use of GIS software, quantitative exposure science, and using novel paradigms for hazard identification. Her experience includes assessing human health risk from exposure to a variety of chemical agents, such as volatile and semi-volatile organic compounds (e.g., benzene, methacrylates, toluene), metals / metalloids (e.g., lead, arsenic, cadmium, nickel), perflourinated compounds (e.g., perfluorooctanoic acid or PFOS), and silicates (e.g., asbestos, crystalline silica).

Prior to joining Exponent, Ms. Dahlberg received her M.S. in environmental health sciences with a concentration in toxicology from UC Berkeley School of Public Health. Additionally, she brings a strong foundation in the core sciences. She received her B.S. in biology and B.A. in chemistry from Pepperdine University, where she was heavily involved in laboratory research in the fields of microbiology and physical chemistry.

Project Experience

Proposition 65

Conducted Proposition 65 evaluations to assess potential exposure to metals (e.g., arsenic, cadmium, lead) and semi-volatile organic compounds (e.g. methylene diphenyl diisocyante) during various consumer product use scenarios. Example products include appliances and tableware.

Evaluated reproductive toxicity and developmental neurotoxicity outcomes reported in published studies concerning a pesticide that is undergoing review by the Proposition 65 Developmental and Reproductive Toxicant Identification Committee (DARTIC).

Exposure Simulations

Simulated the use of a colored cosmetic product and quantified potential personal breathing zone exposures to respirable crystalline silica. Contextualized data in terms of lung cancer risk, using established regulatory guidance.

Pharmacoepidemiology

Conducted a systematic literature review and critically assessed the peer-reviewed literature of pharmaceutical contaminants and potential health effects. Reconstructed acceptable intake limits for contaminants from animal studies.

Dermal Sensitization

Conducted testing to understand the potential for known dermal sensitizers to leach from wearable products during use. Used leach data in a model to predict allergic contact dermatitis elicitation risk. Utilized common chemical databases (e.g. PubChem, ECHA, ATSDR) to identify potential dermal sensitizers and dermal irritants in consumer products.

Litigation Support

Reviewed discovery documentation and generated narratives of plaintiff exposure histories in support of expert testimony in asbestos and talc product liability litigation. Described the nature of alleged exposures (e.g., frequency, duration) to the product of interest and other relevant exposure risk factors (e.g., tobacco smoke, therapeutic radiation).
