Select Projects

Human and Environmental Risk Assessment:  Conducted a literature review to evaluate the state of science on microplastics generated by paints and coatings.

Causation Analysis:  Evaluated the association of occupational exposures to heptane, methanol, propanol, butanol, silica, formaldehyde, and other substances, with risk of a health outcome.

Causation Analysis:  Evaluated the risk of cancer and non-cancer effects associated with occupational exposure to perchloroethylene and trichloroethylene. 

Environmental Risk Assessment:  Generated a database of over 1,000 chemicals present in vehicle fluids or tires along with acute toxicity data in Puget Sound salmon in an assessment to identify chemicals that may be associated with urban runoff mortality syndrome in Pacific salmon.

Product Stewardship:  Conducted a quantitative risk assessment that concluded that a mandated safety test of a children’s toy altered the product’s chemical structure, which led to unrealistic estimates of health risks to children from exposure to boron. 

Toxicology Support:  Provided support in a suite of toxic tort cases of former railroad workers alleging cancers due to occupational exposures to diesel exhaust, benzene, silica dust, asbestos, creosote, herbicides, and other substances.

Chemical Product Evaluation:  Providing ongoing support to a city chemical reduction program by evaluating the hazard to human and ecological receptors, and exposure potential (e.g., persistence and bioaccumulation properties), of numerous pesticide and herbicide products.  The evaluations are used to identify and prioritize products for the city’s chemical reduction program.
