Environmental Chemistry In The Lab

The present book is meant for the students who opt for a course in Environmental Chemistry with laboratory work as a component of the course. Spread in 72 experiments the analyses of soil, water and air have been described in a simple manner so that most of these experiments can be conducted even by the beginners in this subject. The principles involved, preparation of the reagents and the procedures are described for each experimental method. The authors hope that this manual would prove to be useful in laboratories where soil, water and air are routinely tested

Experiments in Environmental Chemistry presents experimental activities that provide practical, first hand experience in the observation of chemical processes occurring in the environment. A variety of techniques with applications in governmental laboratories, industry, and research are described. The experiments are divided into five parts: biochemical processes in aquatic systems; toxic substances in the environment; food additives and contaminants; chemical ecology; and field surveys. This book is divided into five sections and begins with a discussion on the transformations of carbon, nitrogen, phosphorus, and energy in aquatic systems. Various aspects of environmental chemistry including photosynthesis, respiration, biogeochemical cycling, primary production, plant nutrients, water quality, eutrophication, and wastewater treatment are considered. The next section focuses on a wide assortment of environmental contaminants in terms of their behavior and occurrence in various sectors of the environment. In this section, the reader is introduced to gas chromatography, atomic absorption spectroscopy, thin layer chromotography, column chromatography, and techniques for the measurement of atmospheric contaminants. Food and the occurrence of foreign substances that result from deliberate additions or other processes are also analyzed, along with chemical compounds such as allelochemicals, pheromones, and chemical defense substances. This monograph will be a valuable resource for environmental chemists.

This book presents chemical analyses of the most pressing waste, pollution, and resource problems for the undergraduate or graduate student. Its distinctive holistic approach provides a solid introduction to theory as well as a practical laboratory manual detailing beginning and advanced experimental applications. It presents laboratory procedures at microscale conditions, for minimum waste and maximum economy.

Environmental Chemistry in the Lab presents a comprehensive approach to modern environmental chemistry laboratory instruction, together with a complete experimental experience. The laboratory experiments have an introduction for the students to read, a pre-lab for them to complete before coming to the lab, a data sheet to complete during the lab, and a post-lab which would give them an opportunity to reinforce their understanding of the experiment completed. Instructor resources include a list of all equipment and supplies needed for 24 students, a lab preparation guide, an answer key to all pre-lab and post-lab questions, sample data for remote learners, and a suggested rubric for grading the labs. Additional features include: • Tested laboratory exercises with instructor resources for environmental science students • Environmental calculations, industrial regulation, and environmental stewardship • Classroom and remote exercises • An excellent, user-friendly, and thought-provoking presentation which will appeal to students with little or no science background • A qualitative approach to the chemistry behind many of our environmental issues today

This lab manual provides an interdisciplinary collection of 23 extensively tested environmental chemistry experiments — with extensive introductory background material for each experiment. It covers a broad range of methods and provides detailed instructions on calculation of results. Experiments involve, for example: inorganic and organic profile of sediment and soil cores; the pH of environmental waters and buffer capacity; alkalinity of streams and lakes; trace levels of ions in natural waters; conductivity of natural waters; cloride ion in natural waters; colorimetry and absorption spectra; metals in natural waters and in sediments; atomic absorption spectrometry; the chemical oxygen demand of natural waters and wastewaters; the fluorimetric determination of polycyclic aromatic hydrocarbons; environmental hydrocarbons; air sampling-particulates in urban air; carbon dioxide in the atmosphere; acid rain; decomposition of pollutants with an application to plasticizers, and detergents. For chemists and technicians with environmental agencies.

A comprehensive set of real-world environmental laboratoryexperiments This complete summary of laboratory work presents a richlydetailed set of classroom-tested experiments along with backgroundinformation, safety and hazard notes, a list of chemicals andsolutions needed, data collection sheets, and blank pages forcompiling results and findings.

This self-contained text offers all the information necessary for readers to understand the topics surrounding environmental science and the chemistry underlying various issues. Environmental Chemistry in Society, Third Edition, provides a foundation in science, chemistry, and toxicology, including the laws of thermodynamics, chemical bonding, and environmental toxins. This text allows readers to delve into environmental topics such as energy in society, air quality, global atmospheric concerns, water quality, and solid waste management. The arrangement of the book provides instructors with flexibility in how they present the material, with crucial topics covered first. This Third Edition has been updated throughout. The book provides a statement of learning outcomes at the beginning of every chapter, group work questions to encourage learning and environmental awareness, and discussion questions to develop critical thinking skills. The Third Edition includes more illustrations than previous editions, and the energy chapter of the Second Edition has been divided into two chapters in this edition to make the topic more manageable. An inclusive international approach highlights the contributions of scientists from around the world. Chemical structures are presented with inline figures. FEATURES Offers a user-friendly approach to appeal to students with little or no science background Presents a qualitative approach to the chemistry behind many current environmental issues Updates environmental data Includes a glossary of important terms The environmental data has been updated to include the effects of COVID-19. A test bank is available to instructors upon request.
