ICF Environment Environmental Risk + Toxicology

Environmental Risk + Toxicology

ICF International uses sophisticated research and modeling to develop multimillion-dollar, multi-year environmental risk and toxicology analysis efforts for U.S. federal agencies and international industries.



As a pioneer in human health and environmental risk assessment, ICF’s highly credentialed, widely published experts provide clients with solid, broad-based analysis that stands up to intense scrutiny—a firm foundation for credible decision-making. We are acutely aware of budgets and cost concerns, timing, regulatory issues, and other business realities. Furthermore, ICF’s professionals can effectively communicate the complexities of environmental risk to target audiences worldwide.

ICF environmental risk and toxicology services include:

  • Quantitative dose-response assessment and modeling
  • Physiologically based pharmacokinetic modeling
  • Mammalian toxicology and ecotoxicology reviews
  • Hazard, safety, and exposure assessments
  • Children’s environmental health assessments
  • Multimedia fate and transport modeling
  • Research coordination and communication

ICF is well grounded in the fundamentals of risk assessment: hazard identification, dose-response assessment, exposure assessment, and risk characterization. We are expert in risk issues for a wide range of substances, including:

  • Mercury
  • Dioxin
  • Lead
  • Pesticides
  • Microbial contaminants
  • Pharmaceutical residues
  • Radionuclides
  • Criteria and hazardous air pollutants

ICF experts are also skilled in compliance with the European Commission’s regulatory system—Registration, Evaluation, Authorisation and Restriction of Chemicals (REACH). We provide guidance based on sophisticated integration of environmental science, IT, socioeconomic analysis, and organizational design to help clients lead their businesses toward strategic planning to realize opportunities in Europe.


Featured Resources

  • Exposure assessment—ICF conducts exposure assessments to estimate the potential exposures to humans and the environment from pollutants in land, air, and water. Our expertise extends to the development of multimedia fate and transport models that assess human exposures via drinking water consumption, incidental soil ingestion, fish ingestion, and ingestion of agricultural products.
  • Toxicology—Through the systematic review of toxicology and epidemiology data, ICF identifies and quantifies the effects of pollutants or contaminants on human health and the environment.  Our evaluations are used to support premarket safety assessments, hazard assessments, and risk assessments.
  • Risk modeling—ICF employs the latest advances in physiologically-based pharmacokinetic (PBPK) and benchmark dose (BMD) modeling in our risk assessments.  Our capabilities also include customized risk model development, fault tree and other probabilistic analyses, and uncertainty analysis.
  • Air quality modeling—ICF is adept at the development and application of regional- and urban-scale air quality modeling techniques and innovative approaches to environmental data analysis. Our specialties include meteorological and air quality data analysis, emission inventory preparation and quality assurance, meteorological modeling, and development and application of air quality models.
  • Research coordination and communication—ICF develops reports and other outreach materials that interpret and communicate environmental research results to a variety of audiences. We also provide support for peer reviews, expert workshops, scientific meetings, and training.
  • U.S. Environmental Protection Agency (EPA)
  • U.S. Food and Drug Administration (FDA)
  • U.S. Department of Agriculture (USDA)
  • National Institute of Environmental Health Sciences (NIEHS)
  • Chemical companies/consortia subject to Registration, Evaluation, Authorisation and Restriction of Chemicals (REACH)
  • State and local agencies
  • Project

    Science Summary Reports

    ICF supported EPA in developing science summary reports that interpret and communicate environmental research results.

  • Project

    Mercury Deposition Modeling for the Virginia Mercury Study

    ICF conducted air quality modeling to assess atmospheric mercury deposition to water bodies in the Commonwealth of Virginia as part of the Virginia Mercury Study.

  • Project

    Exposure and Risk Assessment Support for Review of NAAQS for Lead

    ICF conducted a quantitative human exposure and health risk assessment in support of a 2008 review of the National Ambient Air Quality Standard (NAAQS) for lead.

  • Project

    Dioxins Risk Assessment

    ICF is supporting EPA in analyzing human health risks associated with exposure to 2,3,7,8-TCDD in order to develop a response to comments from the National Academy of Sciences on EPA's 2003 reassessment of health risks from dioxins and related compounds.

  • Project

    Children's Environmental Health Research Report

    ICF prepared a topical summary of EPA's children's health research portfolio, its broader impact on the state of the science, and its potential for improving the health of the nation's children.

  • Project

    America’s Children and the Environment (ACE)

    ICF International has supported the U.S. Environmental Protection Agency's (EPA) America's Children and the Environment (ACE) project since its 1999 inception.
