Instructor: Dr. Philip J. Silva, 024 Widtsoe, 797-8192, psilva@cc.usu.edu
Office Hours: Monday and Wednesday, 1:30-2:20; Thursday 3:00-4:00
Prerequisite: Science Breadth Class
Text (required): Stanley E. Manahan Environmental Chemistry 8th
Edition, Lewis Publishers 2005
Supplemental Texts: handouts, web
Course Content: This course is a survey of chemical fate and transport
in the environment as well as chemical impacts on the environment on both
a local and global basis. The course will focus on the foundation of
air, soil, and water, the three main media when one discusses the environment,
as well as multi-phase interactions.
Learning Objectives: Below is a list of specific learning objectives for Environmental Chemistry
1) Distinguish between the different “spheres” of the natural environment
2) Demonstrate knowledge of interactions between all states of matter (solid,
liquid, gas)
3) Comprehend the importance of photochemistry to air pollution
4) Comprehend the chemical mechanisms causing the greenhouse effect and the
uncertainty associated with resulting global climate change
5) Recognize the impact of aqueous phase chemistry, especially the importance
of pH on the impact of water pollutants
6) Demonstrate knowledge of the chemistry and treatment of hazardous wastes
7) Comprehend the concept of industrial ecosystems and their application
to future technological changes and innovations
8) Distinguish the measures of toxicological impacts of pollutants
Lectures: Lectures will build from basic elements of air, soil, and water chemistry to enhance our understanding of problems associated with pollution from natural and anthropogenic substances. Emphasis will be on chemical reactions, chemical equilibrium, transport, chemical degradation, and toxicological effects. All phases will be considered; water pollution in the hydrosphere; stratospheric ozone depletion, urban smog in the atmosphere; and soil and subterranean pollution in the lithosphere.
Homework: Reading exercises from the text book and outside sources will be assigned. Students will be expected to find, read, and interpret articles found in the popular and scientific literature. Students will also learn how to use the internet to research topics associated with environmental pollution. All students will also give one short (~10 minute) presentation on a topic of interest to the class during the semester.
Examinations: There will be three examinations, each worth 100 points. They will be based on the environmental chemistry of the hydrosphere, lithosphere, and atmosphere, respectively. Examination questions will be drawn from homework (out-of-class exercises, reading, and problems from the book) and concepts addressed in the lectures. Examinations may be partially or totally "take-home" in nature.
Grading: Grades will be based on your participation in class, performance on homework assignments, examinations, and one oral presentation. Point scores will be added and a percent score calculated. The guaranteed grade cut-off of 90+% A, 80%-89% B, 70%-79% C, 55%-69% D will be used. +/- scores will be used as prescribed in the university catalog. The percentile scores may be adjusted upward to curve the percent scores if the examinations appear to be too difficult and if the class, as a whole, does not perform well on specific questions.
Withdrawals and Incompletes: Withdrawals will follow
the deadlines listed in the Spring 2005 schedule of classes. Students
are required to complete all courses for which they are registered by the
end of the semester. In some cases, a student may be unable to complete all
of the course work because of extenuating circumstances as defined in the
schedule of classes. However, you must notify me before the end of
the semester if you want to be considered for an incomplete
Attendance: Attendance will not be taken. However, attendance
is suggested for successful performance as lectures will not always follow
the book and class participation is considered in grading.
Disabilities: Any student with a disability that requires accommodations
must contact the instructor. The disability must be documented
by the Disability Resource Center.
