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.

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

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.

New techniques, improved understanding and changes in regulations relating to environmental analysis means that students, technicians and lecturers alike need an up-to-date guide to practical environmental analysis. This unique book provides detailed instructions for 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 and instrumentation. The content is supported by theoretical material explaining, amongst other concepts, the principles behind each method and the importance of various pollutants. Also included are suggestions for projects and worked examples. Appendices cover environmental standards, practical safety and laboratory practice. Building on the foundations laid by the highly acclaimed first edition, this new edition has been revised and updated to include information on new monitoring techniques, the Air Quality Index, internet resources and professional ethics. Like its predecessor, this informative text is certain to be valued as an indispensable guide to practical environmental analysis by students on a variety of science courses and their lecturers. Reviews of the first edition: "I strongly urge academics in chemistry, biology, botany, soil science, geography and environmental science departments to give [this book] serious consideration as a course text." Malcolm Cresser, Environment Department, University of York, UK "Destined to become a course text for many university courses ... a high quality, informative introductory text ... there should be multiple copies on most university's library shelves."

Green chemistry involves designing novel ways to create and synthesize products and implement processes that will eliminate or greatly reduce negative environmental impacts. Providing educational laboratory materials that challenge students with the customary topics found in a general chemistry laboratory manual, this lab manual enables students to see how green chemistry principles can be applied to real-world issues. Following a consistent format, each lab experiment includes objectives, prelab questions, and detailed step-by-step procedures for performing the experiments. Additional questions encourage further research about how green chemistry principles compare with traditional, more hazardous experimental methods.

Developing microscale chemistry experiments, using small quantities of chemicals and simple equipment, has been a recent initiative in the UK. Microscale chemistry experiments have several advantages over conventional experiments: They use small quantities of chemicals and simple equipment which reduces costs; The disposal of chemicals is easier due to the small quantities; Safety hazards are often reduced and many experiments can be done quickly; Using plastic apparatus means glassware breakages are minimised; Practical work is possible outside a laboratory. Microscale Chemistry is a book of such experiments designed for use in schools and colleges, and the ideas behind the experiments in it come from many sources, including chemistry teachers from all around the world. Current trends indicate that with the likelihood of further environmental legislation, the need for microscale chemistry teaching techniques and experiments is likely to grow. This book should serve as a guide in this process.

Modern application: car battery Tu Youyou b. 1930 Extract compounds from plants. Modern application: pharmaceuticals and cosmetics People have been tinkering with chemistry for thousands of years. Whether out of curiosity or by necessity, Homo sapiens have long loved to play with fire: mixing and boiling concoctions to see what interesting, beautiful, and useful amalgamations they could create. Early humans ground pigments to create durable paint for cave walls, and over the next 70 thousand years or so as civilizations took hold around the globe, people learned to make better medicines and discovered how to extract, mix, and smelt metals for cooking vessels, weapons, and jewelry. Early chemists distilled perfume, made soap, and perfected natural inks and dyes. Modern chemistry was born around 250 years ago, when measurement, mathematics, and the scientific method were officially applied to experimentation. In 1896, after the first draft of the periodic table was published, scientists rushed to fill in the blanks. The elemental discoveries that followed gave scientists the tools to visualize the building blocks of matter for the first time in history, and they proceeded to deconstruct the atom. Since then, discovery has accelerated at an unprecedented rate. At times, modern chemistry and its creations have caused heartbreaking, unthinkable harm, but more often than not, it makes our lives better. With this fascinating, hands-on exploration of the history of chemistry, inspire the next generation of great scientists.
