The Program

Coordinator of the Collaborative Program, D. Lean

Toxicology is the study of the effects of poisons on living systems. These poisons can be either inorganic, synthetic, or natural organic materials. As a field of research, toxicology cuts across traditional disciplinary boundaries such as chemistry, biology and psychology. While individual researchers usually specialize in a particular area, toxicologists today must be able to appreciate significant research in other fields and therefore require an understanding of the basic principles of other disciplines. To meet this challenge, Carleton University and the University of Ottawa offer a multidisciplinary collaborative program in toxicology leading to the degree of the Master of Science.

The collaborative program is intended to augment the research and training which the student receives through one of the institutes or departments which participate in the program.

The primary or degree-granting participating departments or institutes are:

• The Ottawa-Carleton Institute of Biology, which consists of the Departments of Biology at Carleton University and the University of Ottawa
• The Ottawa-Carleton Chemistry Institute, which consists of the Departments of Chemistry at Carleton University and the University of Ottawa
• The Department of Psychology, Carleton University

The collaborative program is coordinated by a committee of representatives of these participating units.

Applications should be directed to the primary participating unit which is most appropriate to the student’s research interests. Once accepted into the institute or department, students must be sponsored into the collaborative program in chemical and environmental toxicology by a faculty member involved in the program. This will normally be the student’s supervisor. The student is responsible for fulfilling the requirements for the master’s degree of the department and the institute and the additional requirements of the collaborative program.

Application forms and further information may be obtained by writing directly to any of the three participating institutes or departments.

Master’s Program

Admission Requirements

The requirements for admission to the master’s program in chemical and environmental toxicology are as follows:

• Prior admission to the master’s program of the primary institute or department which participates in the collaborative program
• A letter of recommendation from a participating faculty member of the collaborative program, which both recommends admission and indicates the willingness of the faculty member to supervise the candidate’s research program in chemical and/or environmental toxicology

Students must normally have obtained a high honours GPA in their undergraduate and/or graduate course work in order to be recommended for admission to the collaborative program.

Program Requirements

Students must fulfil the requirements for the primary academic unit in which they are enrolled (biology, chemistry, or psychology). The requirements for the collaborative program in chemical and environmental toxicology include:

• Principles of Toxicology
• Seminar in Toxicology
• One additional 0.5 credit in toxicology
• A research thesis on a topic in toxicology supervised by a faculty member of the collaborative program in chemical and environmental toxicology

The degree awarded will in each case specify the discipline of the participating unit with specialization in chemical and environmental toxicology.

Graduate Courses

Not all of the following courses are offered in a given year. For an up-to-date statement of course offerings for 1998-99, please consult the Registration Instructions and Class Schedule booklet published in the summer.

F,W,S indicates term of offering. Courses offered in the fall and winter are followed by T. The number following the letter indicates the credit weight of the course: 1 denotes 0.5 credit, 2 denotes 1.0 credit.

Other courses listed in the calendar under the primary academic units of psychology, biology, or chemistry may be taken, with the approval of the student’s supervisory committee, as options in addition to the basic requirements of the degree in chemical and environmental toxicology.

Biology 61.642F1 (BIO9101)
Principles of Toxicology

The basic theorems of toxicology with examples of current research problems. The concepts of exposure, hazard and risk assessment will be defined and illustrated with experimental material from some of the more dynamic areas of current research.
(Also listed as Chemistry 65.578(CHM8156) and Psychology 49.525)

Biology 61.643F1 (BIO9104)
Ecotoxicology

Selected topics and advances in ecotoxicology with emphasis on the biological effects of contaminants. The potential for biotic perturbance resulting from chronic and acute exposure of ecosystems to selected toxicants will be covered, along with methods of pesticide, herbicide and pollutant residue analysis and the concept of bound residues.
Prerequisite: Biology 61.642(BIO9101)

Biology 61.645W1 (BIO9105)
Seminar in Toxicology

A course in seminar format highlighting current topics in toxicology. The course will feature student, faculty and invited seminar speakers.
(Also listed as Chemistry 65.585(CHM8167) and Psychology 49.526)

Chemistry 65.579 (CHM8157)
Chemical Toxicology

An advanced course in chemical toxicology which deals with both chemical hazard and exposure. An overview of the empirical data relating to the toxicity of various classes of chemicals to test organisms is followed by a treatment of toxicity at the cellular level, including studies of interaction between toxic substances and enzymatic systems. This is the type of data which a student could apply to the interpretation and monitoring of the new WHMIS health regulations. Initial events in enzyme induction and mutagenesis are considered. Predictive capacities in the areas of structure-activity relationships and mechanisms of enzyme induction are considered, followed by an assessment of mechanisms of exposure to toxic chemicals.

Psychology 49.524F1, W1
Principles and Methods in Behavioural Toxicology

A course examining the basic concepts of behavioural toxicology starting with a general discussion of behaviour testing methodology and then focusing on procedures used in screening chemicals for behavioural effects, and more advanced tests. Controversial examples from current research are used to illustrate the practical problems of assessing both animal and human behavioural toxicity.
