Department of Environmental and Radiological Health Sciences

Toxicology is the study of the effects of chemicals and other potentially harmful agents on biological systems. The field draws upon the sciences of biology, chemistry, biochemistry, physiology, cell and molecular biology, neuroscience, and pathology. The core curriculum provides a comprehensive background in toxicology, enhanced by elective offerings in the department and the many related basic and health science courses available at CSU.

The M.S. in Toxicology, Plan A, prepares students for industry, government, and academia research careers. Graduates also find professional employment in public and private sector positions such as environmental protection, risk assessment, or product safety evaluation. This program provides an excellent basis for students seeking admission to a doctoral degree program in toxicology or a related field.
