Mr. Ken Unice is a Principal Health Scientist with more than 20 years of quantitative human health risk, exposure assessment, and environmental modeling experience. His expertise is the application of environmental fate and transport models and risk assessment principles in occupational, community, consumer product and environmental health evaluations. Mr. Unice has co-authored more than 50 peer-reviewed journal articles and 100 conference abstracts on the topics of environmental fate and transport, toxicokinetics, biomonitoring, metals exposure, pathogen risk assessment, exposure reconstruction, and subsurface bacterial transport. Mr. Unice is proficient in a variety of mass-transfer theories used to estimate the fate of chemicals in the indoor environment, occupational settings, as well as in environmental matrices including soil, sediment, water and air.

Mr. Unice has managed exposure assessments, risk assessments, probabilistic assessments, and risk ranking evaluations for a variety of commercially important compounds. He has performed health evaluations in a number of industries, including the rubber, energy, chemical manufacturing, household consumer product, paper products recycling. Mr. Unice also has extensive experience in applied research and study design, as well as managing contract research organizations. He has published a number of novel methods characterizing tire and road wear particles (TRWP) in air, soil and sediment. He has also published innovative studies addressing the distribution of cobalt in the human body, the integrated environmental modeling of PFOA manufacturing emissions, and a mass balance microplastics modeling methodology focused on a European watershed. Mr. Unice has also served as an invited peer reviewer of several U.S. EPA technical approach documents or proposed models.
