Course Description: This course introduces students to the general principles underlying the health effects of environmental agents. Students will gain an understanding of the mechanisms of interactions between environmental agents and living systems. This course will enable students to apply information derived from fundamental microbiology and toxicology studies to assessment of the health hazards associated with exposure to environmental agents, and to predicting the health effects of novel agents.


Prerequisites:  Biology, chemistry through organic, mathematics through calculus; biochemistry is recommended. If these prerequisites are not all met: students may remedy weak areas by independent study (suitable texts are listed below), and permission of the course coordinator is required.

Grading Opportunities: Grades will be based on twelve homework sets, two in-class examinations, and one final examination.

Homework Sets: The homework sets will consist of three short-answer questions and one question requiring more extensive reasoning. Sets will be handed out on Fridays and will be due the following Friday. Completed homework sets are to be placed in the box marked "ENVR 430 HOMEWORK SETS," located on the desk of Ms. Robin Whitleyin Room 148  Rosenau Hall.  Homework sets should be submitted by 5:00 PM on the day they are due.

Each homework set counts for 5% of the total course grade; collectively, these sets count for 60% of the entire course grade. Each homework set is weighted equally.  The following grading scheme is used:
 

%
  Descriptor  Assigned Grade  Undergraduate Grade
90 - 100
