He has investigated and evaluated exposures to welding fumes, lead, organic solvents, coal, silica, elongate mineral particles, total and respirable dust, vibration, diesel particulate matter, and noise in open pit and underground mining environments and construction sites. He has also evaluated work practices and potential airborne concentrations of pesticides during periodic office environment applications, evaluated exposures to diesel particulate matter, total volatile organic compounds, and noise in recycling facilities, and characterized exposures and human health risks associated with potential ammonia exposures during hair dying procedures in salons. He has consulted on toxicology and industrial hygiene issues for government research facilities, geological and pharmaceutical companies, the plastics industry, wastewater treatment plants, oil and gas exploration sites and production facilities, general manufacturing, and renewable energy sites. Mr. Rasmuson was recently the principal investigator for a Center for Disease Control and Prevention, National Institute of Occupational Safety and Health, Mountain and Plains Education and Research Center Pilot Research Project: “Monitoring and Modeling of Exposures during Auto-Mechanic Degreasing Operations.” This grant characterized organic solvent exposures during manual auto-parts degreasing operations and correlated two-zone, near-field far-field mathematical models against real-time measurements. Other research interests include the application of statistical methodologies to characterize exposures and risks, evaluation of risk assessment uncertainty through sensitivity analysis, application of biostatistical methods to evaluate precision and accuracy of the exposure reconstruction process, and the unification of quantitative and qualitative aspects of epidemiological studies to better characterize potential risk from harmful agents.
