While there have been many claims of the benefits of teas through the years, and while there is nearly universal agreement that drinking tea can benefit health, there is still a concern over whether the lab-generated results are representative of real-life benefit, what the risk of toxicity might be, and what the effective-level thresholds are for various purposes. Clearly there are still questions about the efficacy and use of tea for health benefit. This book presents a comprehensive look at the compounds in black, green, and white teas, their reported benefits (or toxicity risks) and also explores them on a health-condition specific level, providing researchers and academics with a single-volume resource to help in identifying potential treatment uses. No other book on the market considers all the varieties of teas in one volume, or takes the disease-focused approach that will assist in directing further research and studies. Interdisciplinary presentation of material assists in identifying potential cross-over benefits and similarities between tea sources and diseases Assists in identifying therapeutic benefits for new product development Includes coverage and comparison of the most important types of tea - green, black and white

Human activities have dramatically changed the composition and organisation of soils. Industrial and urban wastes, agricultural application and also mining activities resulted in an increased concentration of heavy metals in soils. How plants and soil microorganisms cope with this situation and the sophisticated techniques developed for survival in contaminated soils is discussed in this volume. The topics presented include: the general role of heavy metals in biological soil systems; the relation of inorganic and organic pollutions; heavy metal, salt tolerance and combined effects with salinity; effects on abuscular mycorrhizal and on saprophytic soil fungi; heavy metal resistance by streptomycetes; trace element determination of environmental samples; the use of microbiological communities as indicators; phytostabilization of lead polluted sites by native plants; effects of soil earthworms on removal of heavy metals and the remediation of heavy metal contaminated tropical land.

Tea is a popular non-alcoholic beverage that maintains exclusivity as well as mass appeal for respite and relaxation. Tea is fast gaining importance for its health benefits as a nutraceutical. In addition to its global end-use, tea plantations as a whole are undergoing a transition towards mechanization, and agro-technolotgies for farm mechanization have been rationalized. With the advent of biotechnological approaches, management of genetic resources and plant improvement are evolving, both for improving productivity and quality under normal and stress environments. Tea manufacture is also undergoing process of transformation due to the advent of new machines with precise and controlled steps of manufacture. Pre-withering machine is a disruptive concept in tea processing and is highlighted in this book. Various diversified health care products e.g. theaflavins, polyphenols, theanines decaffeinated tea etc. are getting place in the market. Fast teas viz., Ready-to-Drink teas, tea concentrates, instant tea, tea based juices and tea wines are in queue for impacting the markets. In this book, effort has been made to bring together the latest advances on aspects of tea husbandry, physiology, biochemistry, manufacture and biotechnology to give a one stop exposition of status on Tea Technology to the reader.

Pesticides are now accepted as an integral part of modern agricultural production. This book provides analysis of the steps taken by national and international bodies working towards a cohesive global strategy for evaluating the safety of residues in food that result from approved pesticide uses. Also described is the role of the UN Food and Agriculture Organization (FAO), World Health Organization (WHO) and Codex Alimentarius in developing standards that protect the health of the consumers and ensure fair practices in the food trade. It goes on to look at the promotion of good agricultural practice in the use of pesticides and the need for control in their practical use. These include sampling, testing the compliance of marketed products against legal limits and verifying the effectiveness of the safety-based regulatory measures. This is a specialist book for those looking to go into the field of international food safety, for students and lecturers studying the topic, for policy makers working on public health and agricultural issues, and personnel responsible for taking samples and performing the analysis of pesticide formulations and residues.

This volume focuses on the most recent trends for greening analytical activities beginning with an introduction to green analytical chemistry followed by a discussion of green analytical chemistry metrics and life-cycle assessment approach to analytical method development. The chapters discuss two main topics; first is the most recent techniques for greening sample pretreatment steps, and second is modern trends for tailoring analytical techniques and instrumentation to implement the green analytical chemistry concept. The role of different kinds of green solvents, such as ionic liquids, supercritical fluids, deep eutectic solvents, bio-based solvents, and surfactants, as well as nanomaterials and green sorption materials in greening sample extraction steps is also a focus of this book. Furthermore, different approaches for greening chromatography as a key analytical technique are discussed. The applications of nanomaterials in analytical procedures are deeply reviewed, and miniaturization of spectrometers is also discussed as a recently evolved approach for efficient green on-site analysis. This book will appeal to a wide readership of academic and industrial researchers in different fields. It can be used in the classroom for undergraduate and postgraduate students focusing on the development of new analytical procedures for organic and inorganic compounds determination in different kinds of samples characterized by complex matrices composition. The book will also be useful for researchers that are interested in both chemical analysis and environment protection.
