1 CHE 311 Environmental Chemistry COURSE PARTICULARS Course Code: CHE 311 Course Title: Environmental Chemistry No. of Units: 2 Course Duration: Two hours of Lecture per week for 13 weeks. Status: Compulsory Course Address: - Course Webpage: - Prerequisite: nil COURSE INSTRUCTORS Dr. A.F. Aiyesanmi Chemistry Lab. II (inner office) Dept. of Chemistry, Federal University of Technology, Akure, Nigeria. Phone: afaiyesanmi@futa.edu.ng and Mr. G.A. Idowu Analytical/Environmental Chemistry Lab (inner office), Oba Kekere, Dept. of Chemistry, Federal University of Technology, Akure, Nigeria. Phone: gaidowu@futa.edu.ng COURSE DESCRIPTION Chemists play a vital role in monitoring the status of the environment and the quality of environmental resources. As undergraduates of industrial chemistry, this course introduces the students to the concept of the environment as encompassing the entire global space including water (surface, oceans, seas), land, and the atmosphere (air). The course exposes the student to the concept of pollution and how anthropogenic activities have contributed to the pollution of the various phases of the environment. It also teaches the student the determination of different quality parameters in environmental samples, including instrumental techniques and the methods used for water and wastewater treatment. 1

2 COURSE OBJECTIVES The objectives of this course are to: introduce the students to the concept of The Environment ; teach them the characteristics of the main constituents of the environment: Land, Water, and Air; teach the students how to determine and calculate simple physicochemical characteristics of water and wastewater samples; examine the various ways by which human activities have altered the natural environment, resulting into Land, Water and Air pollution;. discuss the various methods of treating waste water and effluents; and introduce the students to instrumental techniques in environmental analysis. COURSE LEARNING OUTCOMES / COMPETENCIES Upon successful completion of this course, the student will: (Knowledge based) be able to explain the meaning of Environment and the characteristics and composition of Land, Water, and Air. understand and be able to explain how anthropogenic activities have contributed to the degradation of the environment and the ways by which these effects can be reduced. understand the various methods of treating wastewater and effluents. have the knowledge of instrumental approach to the determination of contaminants in environmental samples. (Skills) be able to perform simple calculations to determine some basic parameters in environmental samples following analysis. GRADING SYSTEM FOR THE COURSE This course will be graded as follows: Class Attendance 10% Assignments 10% Test(s) 20% Final Examination 60% TOTAL 100% 2

3 GENERAL INSTRUCTIONS Attendance: It is expected that every student will be in class not latter than 15 minutes after commencement of lectures. Attendance records will be kept and used to determine each person s qualification to sit for the final examination. In case of illness or other unavoidable cause of absence, the student must communicate as soon as possible, indicating the reason for the absence. Academic Integrity: Violations of academic integrity, including dishonesty in assignments, examinations, or other academic performances are prohibited. You are not allowed to make copies of another person s work and submit it as your own; that is plagiarism. All cases of academic dishonesty will be reported to the University Management for appropriate sanctions in accordance with the guidelines for handling students misconduct as spelt out in the Students Handbook. Assignments and Group Work: Students are expected to submit assignments as scheduled. Failure to submit an assignment as at when due will earn you zero for that assignment. Code of Conduct in Lecture Rooms and Examination Hall: Students should turn off their cell phones or at most put on silence during lectures. They should not be brought into the examination hall. Noise making during lectures may attract student expulsion from the lecture room. READING LIST 2 Bhata, S.C. Environmental Chemistry.

4 COURSE OUTLINE Week Topic Remarks 1 Introduction to the Environment Student expectation from the course 2 Characteristics of Land/Soil 3-4 Physico-chemical characteristics of water and determination of some water quality parameters will be documented Physico-chemical properties of soil and contribution to environmental equilibrium will be discussed Students will learn how to carry out simple calculations to determine parameters such as alkalinity, total hardness, carbonate hardness, and total dissolved solids in water samples after elemental analysis. 5-6 Characteristics of the Atmosphere. Concept of the elementary cycles; carbon, nitrogen and water cycles. Students will be exposed to the chemistry of the atmosphere and and composition as well as the hydrological cycle 7 9 Sources, types, and effects of environmental pollution Pollution measurement; Introduction to Instrumentation in environmental analysis Wastewater Treatment; composition and disposal of domestic waste. MID-SEMESTER TEST Effects of anthropogenic activities on air, water and soil will be discussed, with emphasis on climate change /global warming, ozone layer depletion, acid rain, eutrophication, etc. Students will be made to participate in listing the various sources and effects of environmental pollution. Methods of sampling and analysis of environmental phases including air, water and soil for pollutants will be discussed. Mention will be made of the use of analytical instruments such as AAS and GC etc, for pollutants determination Composition and basic treatment method of wastewater and domestic waste will be discussed. Methods for the disposal of solid waste will be highlighted. 15 Revision This is the week preceding the final examination. At this time, evaluation will be done to assess how far the students expectations for the course have been met. 4
