Occupational Exposure Assessment

Evaluation of exposure to asbestos-containing materials during boiler, furnace, HVAC, and industrial equipment installation and repair. We analyze insulation, gaskets, packing, and dust-generating tasks through site-specific histories and peer-reviewed air sampling studies.

Historical Knowledge & Regulatory Review

Expert analysis of what companies and regulatory agencies knew about asbestos hazards, when they knew it, and what actions were or weren’t taken to protect workers and consumers.

Expert Witness Testimony

Dr. Paul Rosenfeld and the SWAPE team provide scientifically rigorous, litigation-ready reports and testimony grounded in industrial hygiene, environmental science, and toxicology.

Talcum Powder Exposure Reconstruction

Quantification of asbestos fiber inhalation from regular use of cosmetic talcum powders. We assess product composition, usage patterns, airborne dust levels, and dose-response relationships to determine cancer risk—especially mesothelioma.

Cumulative Dose Calculation

Development of detailed dose models comparing client-specific exposure histories to epidemiological thresholds linked to mesothelioma and lung cancer risk.
