Tamara D. Lunsman, Ph.D.

Senior Environmental Toxicologist

Email VCard Bio

Dr. Lunsman has over 15 years of experience in aquatic toxicology, water quality, and environmental fate and pathways. Her expertise includes evaluating environmental hazards and modeling environmental exposures of pharmaceuticals, personal care products, and other industrial chemicals and products.  She regularly conducts environmental hazard assessments, oversees ecotoxicity testing, and performs alternative and green chemistry evaluations. Her primary responsibilities include reviewing and interpreting ecotoxicity data and applying this information to evaluate site-specific or chemical-specific risks. Dr. Lunsman has an interdisciplinary background in ecological site characterization and remediation, environmental impact analysis, wetland restoration, and regulatory compliance. Dr. Lunsman has 7 years experience managing multidisciplinary natural resource projects for over 15 National Environmental Policy Act (NEPA) documents and natural resource assessments.

Representative Projects

Personal Care Product Environmental Assessment:  Performed several consumer product environmental safety narratives and risk assessments for active ingredients in antimicrobial products in the United States (US) and European Union (EU).  Public and private domain ecotoxicological data were compiled including environmental safety data, product label information, and company sales information to develop toxicity thresholds and derive exposure estimates.  The Exposure & Fate Assessment Screening Tool (E-FAST) was used to estimate environmental exposure in the US and the European Union System for the Evaluation of Substances (EUSES) was used to estimate environmental exposures in the EU.  

Pharmaceutical Environmental Risk Assessment: 
Evaluated the environmental risk associated with the societal use of active pharmaceutical ingredients for several major pharmaceutical companies, compliant with European (EMA) and US (FDA) risk assessment guidelines. Oversaw the collection of environmental fate and toxicity test data.

Hazard Categorization:
  Compiled best available toxicological data on various ecological endpoints to contribute in the determination of hazard categorizations on chemicals.  Performed quality control and quality assurance for the ecotoxicology section of hazard assessments and classified according to the United Nations Globalized Harmonized System (GHS) guidelines.  In the absence of toxicological data, professional judgment was used to determine hazards.

Regulatory Review:  As part of US EPA’s National Ambient Air Quality Standards (NAAQS) review for ozone, prepared regulatory comments on the proposed rule, the welfare risk and exposure assessment, and the policy assessment.

Environmental Impact Assessment:  Provided technical expertise and managed a team of experts to support several Environmental Impact Statements (EISs) for the Naval Facilities Engineering Command (NAVFAC).  Included the preparation of several Biological Evaluations (BEs) in compliance with Section 7 of the Endangered Species Act and Letters of Authorization (LOAs) pursuant to the Marine Mammal Protection Act (MMPA) to assess the potential impacts of naval exercises in sites located along the US east coast.
