Toxicology, Bachelor of Science

Toxicology is an interdisciplinary science that addresses the adverse effects of substances on living organisms caused by chemical, physical or biological agents. The field includes exposure assessment, hazard identification, dose-response analysis, risk characterization and risk management. Toxicologists have the critical responsibility of understanding the effect of exposure to harmful substances found in food, the environment, medicines, licit and illicit drugs and other sources, as well as that of publicizing information of relevance to the public. Through research and education, toxicologists can improve the health and safety of humans and other living organisms and protect the environment in which we live.

The major begins with the foundational science courses common to any degree in the chemical or life sciences: chemistry, biology, organic chemistry, calculus, and physics, with required laboratory work throughout. Then, students take a required core of courses that cover biochemistry, human anatomy and physiology, the basics of toxicology and its major sub-fields (environmental, biomedical, clinical). Students also select one elective course they can focus on their interests and future career goals such as risk assessment, forensic toxicology, and clinical toxicology. Finally, the major includes an advanced capstone experience which brings all of these courses together in the study of a specific research area in toxicology. Students in this major are well-prepared for a variety of careers and graduate programs including PhD programs in toxicology, the life sciences, medical school, and related professional degrees.

Learning Outcomes. Students who successfully complete the Toxicology major will be able to:

Describe the distribution and the toxic mechanism of chemical, physical, and biological agents in the natural and occupational environment.
Identify and describe the diseases or other adverse health effects that may result from exposure to toxic agents and the risk of those outcomes.
Recognize regulatory and management considerations relative to toxic agents.
Apply quantitative methods to measure the concentration or intensity of toxic agents.
Explain and promote interventions to reduce or eliminate exposures to toxic agents.
Interpret and analyze the information on the interaction of natural and man-made toxicants with people, and their impact on human health and disease.
Assess and communicate risk of toxins affecting communities of varied racial, socioeconomic and geographic divisions.

Admission Requirements. Ideally, candidates for John Jay College science majors will meet the following criteria:

1. At least an 81 CAA (High School Academic Average); AND
2. 3 years of High School Math; AND
3. 3 years of High School Science; AND
4. Have taken High School Chemistry Regents OR High School Chemistry course.

Students who wish to transfer into the Forensic Science major must have earned at least 30 credits, have an overall GPA of at least 2.5, and a Math/Science GPA of 2.5 or higher in science major courses to be admitted. In addition, students must have taken Chemistry and Biology courses appropriate to their class standing upon transferring. Students who transfer with less than 30 credits must meet the admissions standards listed above.

Admission requirements. Ideally, candidates for John Jay College science majors will meet the following criteria:

Course information. Placement into BIO 103 and CHE 103 is determined by students' math preparation AND they must be majoring in Toxicology.

Note. At least two science courses and one math course count as STEM variants to satisfy the Common Core general education requirements. If students are exempt from the foreign language requirement, they can use an additional three credits of science towards the Common Core.

Depending on mathematics placement, students may need to take MAT 105 College Algebra and MAT 141 Pre-Calculus as prerequisites for the required calculus course, MAT 151 (formerly MAT 241). Either prerequisite course can satisfy the Required Core: Math and Quantitative Reasoning category of the Gen Ed program.

Honors option. To earn honors in the toxicology major, students must have completed the TOX 401 capstone or the FOS 402 research internship with a grade of B+ or higher, completed all requirements for the major and have earned at least a 3.5 cumulative GPA in courses above the 100-level in the major. Credit for courses required as prerequisites for major courses and transfer credits applied to the major will not be calculated into the major cumulative GPA. Students must have also earned at least a 3.2 overall cumulative GPA. This honor will be noted on the student’s transcript.

Experiential learning opportunities. During their senior year students in the Toxicology program can participate in a variety of experiential learning opportunities. Students may enroll in the undergraduate research course, FOS 402, and participate in a faculty-sponsored laboratory research project. In addition, students may participate in a research experience associated with the capstone seminar course, TOX 401, which culminates in the presentation of original research at a poster session open to the public. In recent years, students have presented their findings at meetings such as the Environmental Club and the Health and Justice Forum.

Additional information. Students who enrolled for the first time at the College or changed to this major in September 2023 or thereafter must complete the major in the form presented here. Students who enrolled prior to that date may choose the form shown here or the earlier version of the major. A copy of the earlier version may be obtained in the 2022-2023 Undergraduate Bulletin.
