ENVIRONMENTAL RISK ASSESSMENT OF HAZARDOUS CHEMICALS

OBJECTIVE

The objective of this course is to provide students with theory and practical experience
in the area of applied environmental toxicology. The course will cover (i) theoretical
principles of environmental distribution and toxicity of pollutants, (ii) practical techniques
for the assessment of the environmental behaviour, toxicity and ecological & human
health risks of contaminants in the environment, and (iii) a critique of current
environmental management practices in Canada. Students apply these techniques in a
class project. The course material is essential for those expecting to be involved in
pollution-related issues.

CONTENT:

1. ENVIRONMENTAL BEHAVIOUR OF CHEMICALS: environmental partitioning,
kinetics of environmental distribution, mass balance, mechanisms of transport &
transformation, fugacity, environmental modeling

2. EXPOSURE ASSESSMENT: mechanisms of chemical uptake & elimination in
organisms, bioaccumulation, trophic transfer and biomagnification, structure-activity
relationships

3. HAZARD & EFFECTS ASSESSMENT: toxicity of chemical pollutants in organisms,
dose-response relationships, toxicity of mixtures of chemicals, ecotoxicity,
carcinogenesis

4. RISK ASSESSMENT: risk quotients, quantitative and probabilistic risk assessment

5. CONTAMINANT MANAGEMENT: application of scientific principles in current
environmental management practices and regulations in Canada, development of
standards & human consumption guidelines, environmental quality criteria, monitoring,
risk assessment, effluent regulations and others

FORMAT: One lecture and one tutorial per week. Tutorials include computer labs and
group discussions.
SCHEDULE: Thursday, 10:30 - 12:20 (lecture) in AQ5005 and Thursday, 1:30 - 2:20 -
Catalog #1817- (tutorial)

EVALUATION: Students are evaluated based on assignment #1 (25% of the final mark),
assignment #2 (30%), 1 student paper/poster presentation (35%) and class contributions
(10%).

READINGS: All readings will be handed out on the first day of classes. All class
overheads will be made available in electronic format on the first day of classes.

OFFICE HOURS: Mondays 10:30 – 12:30 am.
