ENSC 325b-3: Toxicants in the Environment ¨C Sampling and Analysis
Instructor: Dr. Zhi-Qing Lin
Office: 2165 Science West
Lecture Schedule and Location: Tuesdays, 2:00 pm - 4:50 pm, Alumni Hall 0201
Office Hours: By appointment
As the second part of ¡°Toxicants in the Environment¡± (ENSC 325), this course includes both lectures and labs, with a focus on the basic concepts and techniques of environmental sampling, sample preparation, and chemical analyses of environmental toxicants of current concern. Environment measurements, data collection and data analysis and interpretation will also be discussed. The objectives of this course are: (1) Students will become familiar with the basic concepts and principles of environmental sampling and analyses; (2) Students will gain the basic technical skills for environmental measurements and chemical analyses; (3) Students will obtain essential hands-on experience with environmental sampling in the field and chemical analyses in the lab.
Prerequisites: ENSC 325a or consent of Instructor
Credit Hours: 3
Textbook: Sampling and Analysis of Environmental Chemical Pollutants (2nd edition), Emma P. Popek, 2017, Elsevier. Supplementary materials will also be provided on selected topics by the Instructor.
There are two midterm and one final exams. Each exam accounts for 30%. The assignment accounts for 10%. The total point is 100. A: >90; B: 80-90; C:70-80; D: 60-70; F:<60.
Assignments will provide opportunities for students to practice and better understand the materials discussed in classes. Late assignments will be marked down 10% a day, unless arrangements are made with the instructor prior to the due date. Assignments more than 5 days late will not be accepted.
Regular prompt attendance is required for success in this course. Only University approved absences will be accepted. However, excessive absences may result in a 10% reduction of your overall grade or being dropped from the course.
