MS in Environmental Toxicology


Toxicology focuses on identifying, understanding, and analyzing toxic agents and their effects on human health. Research areas include neurological, hepatic, renal, and respiratory systems; prenatal and neonatal development; and carcinogenic and genetic effects of toxicants. Also focuses on risk assessment. Students have opportunities to conduct research on neurological, hepatic, renal and respiratory systems, prenatal and neonatal development, and carcinogenic and genetic effects of toxicants. The goal of the Toxicology program is to provide education in the development, interpretation, and utilization of toxicological data for solving environmental health problems. This requires training in basic biomedical and public health sciences such as Biochemistry and Molecular Biology, Physiology, Epidemiology, and Biostatistics, as well as more specialized studies in Toxicology, Risk Assessment, and Risk Communication.

Likely Careers

Graduates are employed by environmental consulting firms, state and federal health and environmental regulatory agencies, and private industry. They are also well-prepared to pursue doctoral training.


Requirements: Baccalaureate degree, generally in science or engineering, with coursework in Physics, Chemistry, Biology, and Mathematics. GPA minimum of 3.0 for last 90 credits of study. Competitive applicants usually have Graduate Record Examination (GRE) scores above the 65th percentile. No specific subject area tests are required.

Concurrent Option:   A concurrent MPA degree with the Daniel J. Evans School of Public Affairs is available. Applicants must apply and meet the admissions requirements of both the Department of Environmental and Occupational Health Sciences and the Evans School.

Application Deadline:  Dec. 1 for first priority review


Upon satisfactory completion of the MS in Toxicology, graduates will be able to:

  • Define the major classes of toxicants present in the environment and the workplace;
  • Define how toxicants interact with biological systems and the mechanisms by which they elicit adverse effects in humans and other organisms;
  • Recognize sources and modes of exposure to toxic agents;
  • Describe the process by which the risk of adverse effects is assessed;
  • Find and interpret information on toxicological issues in the literature;
  • Analyze toxicological issues and identify significant data gaps concerning health effect of environmental chemicals;
  • Formulate hypotheses and design experiments to test such hypotheses aimed at advancing knowledge on toxicological issues;
  • Organize data and information, prepare written reports and give oral presentations on toxicological aspects of environmental health; and
  • Use toxicological knowledge to solve issues related to the assessment of risk related to environmental or occupational exposures.
