Representative Projects

Analyses of Asbestos Exposure, Health Risks, and State of Knowledge in the Context of Asbestos Litigation: In various industries and settings involving asbestos products and premises, allegedly exposed persons with claimed health effects have included workers in maritime (operating ship, shipyard, and port), steel, foundry, chemical, mining/milling, automotive, and construction industries, and general population building occupants.   

Risk Assessment for Hydraulic Fracturing:  For an oil and gas exploration and production company, evaluated the potential for human health risks from hypothetical surface releases of chemicals associated with hydraulic fracturing.

Air Monitoring Study:  Performed air sampling for lead at an industrial services company facility employing a lead-containing compound.

Causation Assessment:  Evaluated whether exposure to solvents in indoor air, allegedly originating from a flooring product, could have been causally related to claimed health effects.

Risk Communication: Interpreted air monitoring data for diacetyl in a food and beverage industry manufacturer facility, and assisted with communication and control of risks posed to workers. 

Analysis of Exposures from Carbon Nanotube (CNT) Manufacture: Addressed worker and customer health concerns, specifically with regard to potential exposures to polycyclic aromatic hydrocarbons (PAHs) formed unintentionally during production. Helped the client take proper steps to ensure appropriate product stewardship.

Developmental and Reproductive Toxicants (DART) Analyses: Evaluated possible health effects to pregnant workers and their offspring from in utero exposures to chemicals in the workplace. The assessments included a rapid review of the toxicology literature to determine whether the chemicals in question were DART agents, as well as an estimation of worker doses and overall Hazard Indices.

State-of-the-Art Analysis:  For an insurance recovery dispute involving a former industrial complex owner, evaluated what was known about the toxicity and carcinogenicity of trichloroethylene and vinyl chloride at various points in time.
