Generally, I will have regular office hours (the hour after lecture). Students should feel free to come at those times without an appointment. For other times, phone or make arrangements for a time that is mutually convenient. I particularly encourage you to use email to contact me.

Exam Conflicts, Illness etc.

Please advise me of examination conflicts as soon as possible. If you have an illness or other problem, please see your program counsellor and ask them to issue a notice to instructors.

A. The Calendar Description

ENVB-3030 Pesticides and the Environment F,W (3-2) [Note the 2 hours for lab/discussion session is for the term paper in case we need discussion sessions].  The role and use of synthetic and natural pesticides by society and the effects of these pesticides on biological activities in the environment.

Prerequisites: One first year biology course (BIOL1030, BIOL1040 or ZOOL1020) and one organic/environmental chemistry course (CHEM1040 or CHEM2300)

"Chemical and Biological Pesticides in the Environment" by G.R. Stephenson et al. (2000) may be purchased for the course (~$35) from the instructor. This is the same version that was used last semester (Fall 2000), but it differs substantially from those used in prior years. All the material in these notes is fair game in the exams.

B. Objectives of the Course

In addition to addressing the University Learning Objectives, students will learn the following. The student will be expected to be able to recognize and describe chemical groups of pesticides. The student will be expected to be able to define the chemical, physical and biological properties of pesticides which are important in determining their effects on target and non-target organisms in the environment. The student will be expected to predict the probable fate of a pesticide in the environment or choose from a group of pesticides the one most suitable for a particular use if given the relevant information about the pesticide and its proposed use.

C. Synoptic Statement of the Material to be Covered in the Course

* Survey the current use of pesticides in health, agriculture, and forestry.

* Review the various types of pesticides, their classification, their origins and mode of action.

* Discuss pesticide metabolism and residues in food

* Discuss fate and movement of pesticides in the environment.

* Discuss food chains and effects of pesticides on animal and plant life in land and aquatic environments.

* Discuss pesticide resistance.

* Discuss ways to minimize the use and non-target effects of pesticides.

* Discuss the development of biological pesticides and their uses.

* Discuss the registration of pesticides and the regulation of their use.

* Critique popular literature on pesticides and the environment.

D. Academic Honesty and Integrity

It is the student's responsibility to read and to comply with the policies regarding Academic Misconduct at the University of Guelph (see pages 28-30 in the Undergraduate Calendar 2001-2002). Of particular relevance to this course is honesty during exams, honesty in written assignments, and honesty with respect to medical excuses. In fairness to you and to other students in the class, academic misconduct will not be tolerated and will be dealt with firmly.

Examples of academic misconduct in written assignments include: 1) lack of quotation marks: plagiarism has occurred if the author does not place quotation marks around word-for-word copying of print or electronic format source material even though the source is correctly cited; and 2) degree of fidelity to sources - plagiarism has occurred if the author's writing is clearly recognizable as essentially derived from cited or uncited print or electronic format sources, even though the author has altered the original source material by inverting word or sentence order, or substituting synonyms.
