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.

Undergraduate students in environmental science need a foundation in instrumental analysis as much as traditional chemistry majors, but their needs may be quite different. Environmental Chemical Analysis provides an explanation of analytical instrumentation methods for students without a background in analytical chemistry. This second edition features expanded material on sample preparation and quality assurance and control. It also includes new chapters on biological analysis and analysis of environmental particulates. It brings together sampling, sample preparation, and analytical techniques necessary for environmental applications, demonstrated through case studies of actual environmental measurement protocols. Provides comprehensive coverage of all aspects of environmental chemical analysis Explains analytical instrumentation methods for students approaching the subject from a different angle Includes two new chapters on biological analysis and analysis of environmental particulates Expands material on sample preparation and quality assurance/quality control Winner of Choice 2019 Outstanding Academic Title Award

This unique book provides detailed instructions for conducting practical experiments in environmental analysis. The comprehensive coverage includes the chemical analysis of important pollutants in air, water, soil, and plant tissue; and the experiments generally require only basic laboratory equipment. The presentation is supplemented by theoretical material explaining the principles behind each method and the importance of various pollutants. It also includes suggestions for projects and examples of calculations.

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.

Sampling and Analysis of Environmental Chemical Pollutants, A Complete Guide, Second Edition promotes the knowledge of data collection fundamentals and offers technically solid procedures and basic techniques that can be applied to daily workflow solutions. The book’s organization emphasizes the practical issues facing the project scientist. In focusing the book on data collection techniques that are oriented toward the project objectives, the author clearly distinguishes the important issues from the less relevant ones. Stripping away the layers of inapplicable or irrelevant recommendations, the book centers on the underlying principles of environmental sampling and analytical chemistry and summarizes the universally accepted industry practices and standards. This Guide is a resource that will help students and practicing professionals alike better understand the issues of environmental data collection, capitalize on years of existing sampling and analysis practices, and become more knowledgeable and efficient in the task at hand. The three phases of environmental chemical data collection (planning, implementation, and assessment) are explained in a logical and concise manner. A discussion on the physical and chemical properties of environmental chemical pollutants promotes the understanding of their fate and transport. A chapter on common analytical chemistry techniques, methods of compound quantitation, and laboratory quality control and quality assurance may be used as a standalone introduction to instrumental analytical chemistry. Eleven case studies demonstrate the application of the Data Quality Objectives process to the development of sampling designs and illustrate specific data interpretation problems. Numerous call-out boxes in each chapter offer practical tips on widely used industry practices, which originate from years of experience in the field. Appendices contain the most frequently used action levels and reference material, calculation aides, and useful field forms and checklists. Authored by an analytical chemist and environmental pollutant expert with more than 30 years of experience in research and industry.

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
