Environmental Toxicology

College of Agricultural and Environmental Sciences

  • Bachelor of Science

Are you interested in environmental toxins, their environmental fate and regulation, and their impacts on humans and other species? If so, we hope you will consider a major in environmental toxicology. Our graduates are well versed in chemistry, biochemistry, molecular biology and toxicology — and are very unique! They have a tremendous selection of career opportunities upon graduation. With the growing environmental challenges we face today, students in the environmental toxicology major have the cutting-edge education needed to make a significant impact on the future of the world.

Major Requirements

Preparatory courses in biology, chemistry, mathematics and physics provide the fundamental principles which underlie toxicology. Students in the major will learn the environmental fates and biological activities of different classes of toxic substances, and the legislative issues which arise from chemical use. Opportunities are available to develop in-depth understanding in areas of interest, including ecology, environmental chemistry, forensic science, regulatory toxicology, molecular/genetic toxicology, and biomedical toxicology. Hands-on laboratory courses and recommended internships prepare students with practical application for future careers.
