Assessment and analysis of exposure to physical, chemical, and biological contaminants in environmental and occupational settings. Theory and methods of assessing exposure through direct and indirect methods. Introduction to statistical and modeling techniques used in interpreting exposure data, describing sources of exposure variability, and identifying important determinants of exposure.


Exposure assessment is a key component of both environmental epidemiology and environmental risk assessment. Exposure assessment also plays an important role in the evaluation of environmental health interventions. This course provides an introduction to the principles of exposure science and its application to the assessment of human exposure to physical, chemical, and biological contaminants in environmental and occupational settings.


Upon completion of this course students will be able to:
•        Describe the role of exposure assessment, and the potential impacts of exposure misclassification, in epidemiology, risk assessment, and environmental surveillance.
•        Identify commonly used exposure assessment approaches for toxicants in different media and for different routes of exposure.
•        Describe the advantages and disadvantages of direct and indirect exposure assessment approaches.
•        Analyze exposure data using SAS statistical software and clearly summarize the results.
•        Describe the use of remote sensing data and geographic information systems (GIS) in exposure assessment and apply basic GIS tools to environmental exposure data.
•        Critique environmental exposure assessment approaches presented in the literature.

Registrar Notes:


SFU’s Academic Integrity web site http://www.sfu.ca/students/academicintegrity.html is filled with information on what is meant by academic dishonesty, where you can find resources to help with your studies and the consequences of cheating.  Check out the site for more information and videos that help explain the issues in plain English.

Each student is responsible for his or her conduct as it affects the University community.  Academic dishonesty, in whatever form, is ultimately destructive of the values of the University. Furthermore, it is unfair and discouraging to the majority of students who pursue their studies honestly. Scholarly integrity is required of all members of the University. http://www.sfu.ca/policies/gazette/student/s10-01.html


Teaching at SFU in fall 2021 will involve primarily in-person instruction, with approximately 70 to 80 per cent of classes in person/on campus, with safety plans in place.  Whether your course will be in-person or through remote methods will be clearly identified in the schedule of classes.  You will also know at enrollment whether remote course components will be “live” (synchronous) or at your own pace (asynchronous).

Enrolling in a course acknowledges that you are able to attend in whatever format is required.  You should not enroll in a course that is in-person if you are not able to return to campus, and should be aware that remote study may entail different modes of learning, interaction with your instructor, and ways of getting feedback on your work than may be the case for in-person classes.

Students with hidden or visible disabilities who may need class or exam accommodations, including in the context of remote learning, are advised to register with the SFU Centre for Accessible Learning (caladmin@sfu.ca or 778-782-3112) as early as possible in order to prepare for the fall 2021 term.
