A revised edition to the bestselling "The Chemistry of Soils" incorporating new research from the last eight years in the fields of environmental chemistry, ecosystem biogeochemistry, and scientific agriculture.

This second edition demonstrates how chemistry influences the design of water treatment plants and how it should influence the design. Historically, water treatment plants have been designed from hydraulic considerations with little regard to chemical aspects. The many chemical reactions used for removal of pollutants from water simply cannot be forced to occur within current designs. This book re-examines this traditional approach in light of today's water quality and treatment. Will current water treatment processes be sufficient to meet future demands or will new processes have to be devised? Chemistry of Water Treatment assesses the chemical and physical efficacies of current processes to meet the demands of the Safe Drinking water Act, providing expert information to persons responsible for the production of potable water into the next century.

This book looks closely at herbal product development and commercialisation. In spite of an ever-growing demand, there is a dearth of safe and effective herbal products that meet consumers’ expectations. Therefore, this book takes it upon itself to elaborate on the development process of herbal insecticides, repellents and biomedicines from a commercialisation point of view. The introductory chapters deal with the various strategies for disease vector control and provide an overview of herbal biomedicines. The subsequent chapter describes plants with mosquito larvicidal activity, including a comprehensive list of lethal concentrations against different mosquito species. The chapter on Himalayan plants discusses potential botanical insecticide sources and their chemical constituents before delving into the topic of natural insecticides of microbial origin and their efficacy against mosquitoes. Plant-derived insecticides belonging to different chemical classes and the extraction, purification and characterisation of bioactive compounds are illustrated, as well. The recent technological advances in the formulation of microbial, biochemical and botanical insecticides are also reviewed. Three chapters focus on important medicinal plants useful for treating human ailments, with special reference to the traditional healing practices of northeastern India. This is followed by a chapter on the production, use and safety of biopharmaceuticals and edible, plant-based vaccines. The intellectual property issues related to herbal products in India including patents, trademarks, geographical indications, trade secrets and traditional knowledge resources are plainly examined. The book ends with a chapter on the herbal product registration process in India, wherein the data requirements for registration, clinical efficacy trials, toxicity studies, quality control, packaging and labelling are clearly explained. In conclusion, this book is a step-by-step guide for the development of safe, effective and commercially viable herbal insecticides, repellents and biomedicines.

Xenobiotic compounds including pesticides, nitrophenols, pyridine, polycyclic aromatic compounds and polychlorinated biphenyls are widely spread in environment due to anthropogenic activities. Most of them are highly toxic to living beings due to their mutagenic and carcinogenic properties. Therefore, the removal of these compounds from environment is an essential step for environmental sustainability. Microbial remediation has emerged as an effective technology for degradation of these xenobiotic compounds as microorganisms have unique ability to utilize these compounds as their sole source of carbon and energy. The primary goal of this book is to provide detailed information of microbial degradation of many xenobiotic compounds in various microorganisms.
