Select Projects

Radiation Risk Assessment:  Evaluated risks of potential residential exposure to radionuclide contamination in an adjacent landfill, including a variety of cancer and non-cancer human health endpoints and exposure routes.

Skin Sensitization Risk Assessment:  Performed hazard assessments and quantitative risk assessments for skin sensitization and irritation after potential exposure to constituents of various consumer products designed to be in contact with the skin.  Developed exposure levels for potential chemicals of concern intended to protect consumers from adverse skin reactions from contact with the products.

Air Pollution Risk Assessment:  Evaluated risk of a variety of cardiovascular, respiratory, and cancer endpoints and county-wide exposure to constituents of air pollution.

TCE, PCE, and 1,1,1-TCA Risk Assessment:  Evaluated risk of non-Hodgkin lymphoma after potential exposure to TCE, PCE, and 1,1,1-TCA from drinking water and bathing water.

Biological Safety Evaluations:  Evaluated medical devices for biological safety to ensure compliance with US Food and Drug Administration (US FDA) and European Union regulations, and recommended subsequent testing for biocompatibility assessment or justifications to waive testing when feasible.

Product Safety Risk Assessment:  Determined allowable concentrations of various metals and chemicals in cloth uniforms, metallic jewelry, and accessories to prevent adverse reactions from dermal contact and accidental ingestion.
