Book Description
Agrochemicals in Soils contains selected papers from a joint meeting of the Soil Chemistry, Soil Fertility, and Soil Clay Mineralogy Commissions of the International Society of Soil Science, in Jerusalem, Israel. The book is organized into four parts. Parts 1 and 2 deal mostly with the chemical reactions of agrochemicals in the soil. Part 3 explores the movement of agrochemicals in the soil and Part 4 elucidates some aspects of agrochemicals and pollution. Each section begins by one or two invited papers presenting an overview of the topic of the section. Contributed papers follow reporting the results of experimental studies and theoretical analyses of related specific topics. This book will contribute to a better understanding and efficient control of the soil environment.

Book Description
Adsorption, Ion Exchange and Catalysis is essentially a mixture of environmental science and chemical reactor engineering. More specifically, three important heterogeneous processes, namely, adsorption, ion exchange and catalysis, are analysed, from fundamental kinetics to reactor design with emphasis on their environmental applications. In Chapter 1, the subject of air and water pollution is dealt with. Data about pollutants and emission sources are given and the treatment methods are shortly presented. In Chapter 2, the very basics and historical development of adsorption, ion exchange and catalysis are presented as well as their environmental applications. Chapter 3 is devoted to heterogeneous processes and reactor analysis. All types of reactors are described in depth and reactor modelling, hydraulics and mass/heat transfer phenomena are examined for each type of reactor. Chapters 4 and 5 are dedicated to adsorption & ion exchange and catalysis, respectively. The basic principles are presented including kinetics, equilibrium, mass/heat transfer phenomena as well as the analytical solutions of the reactor models presented in Chapter 3. In the sixth chapter, the subject of scale up is approached. The two Annexes at the end of the book contain physical properties of substances of environmental interest as well as unit conversion tables. Finally, nearly all the examples contained are based on real experimental data found in literature with environmental interest. Most of the examples consider all aspects of operation design – kinetics, hydraulics and mass transfer.* Provides basic knowledge of major environmental problems and connects them to chemical engineering

Book Description
This volume ‘Agrochemicals in Soil and Environment: Impacts and Remediation’ is a comprehensive collection of important literature on agrochemical contamination. The main focus of this book is to point out undesirable changes in biological, physical and chemical characteristics of agricultural soils and its impacts on global agricultural crop productivity. Soil is one of the important resources of basic needs for our sustenance but due to various anthropogenic activities like urbanization and industrialization, the soil is losing its basic quality characteristics. Soil microorganisms, water holding capacity, minerals, salts and nutrients are under the direct threat due to agrochemicals therefore, agricultural sector is facing a serious challenge. Lack of proper knowledge and luxurious applications of agrochemicals resulting into degradation and deterioration of soil quality, loss of soil and crop productivity and threatening the food security. Therefore, it is imperative to develop indices, indicators and soil parameters for the monitoring and impact assessment of agricultural contaminants. Further, biotic and abiotic stresses and their tolerance mechanisms in plants in relation to the soil contaminants such as toxic pollutants, heavy metals, inorganic and organic matters, variety of pesticides, insecticides, herbicides, agricultural runoffs and solid wastes, and chemical fertilizers are also highlighted in this volume. This book also discusses causes of reduced agriculture productivity and suggests sustainable measures such as plant-based technologies, bioremediation and nanotechnology, that can be used to overcome the crop losses. The book is interest to research students, teachers, agricultural scientists, agronomists, environmentalists as well as policy makers.

Book Description
Smart Agrochemicals for Sustainable Agriculture proposes products that fulfill the need for chemicals that provide a sustainable delivery system for nutrients necessary to maximize the production of agricultural animals and plants while producing the smallest possible environmental footprint. This book addresses all aspects related to the production process, including chemical formulas, stability of formulations, and the application of the effect of its utilization. Over the past decade, biobased chemicals have received significant attention as candidate resource materials in fertilizers and agrochemicals production due to their renewability. Substitution of conventional raw materials with biobased requires a new approach towards the development of technology. On the other hand, the use of biobased chemicals, such as biostimulants, bioregulators and biofertilizers offers a new palette of products that are natural, thus their application does not pose an impact on the environment (residues) or cultivated plants. - Presents ideas for new products that provide appropriate nutrition while limiting environmental footprints - Includes a full range of the production process, from chemical formulas to establishing the stability of formulations, applications and effects - Offers a host of new products that are natural and whose applications do not negatively impact the environment nor cultivated plants

Book Description
The understanding that some pesticides are more hazardous than others is well established. Recognition of this is reflected by the World Health Organization (WHO) Recommended Classification of Pesticides by Hazard, which was first published in 1975. The document classifies pesticides in one of five hazard classes according to their acute toxicity. In 2002, the Globally Harmonized System of Classification and Labelling of Chemicals (GHS) was introduced, which in addition to acute toxicity also provides classification of chemicals according to their chronic health hazards and environmental hazards.

Book Description
Although chemical pesticides safeguard crops and improve farm productivity, they are increasingly feared for their potentially dangerous residues and their effects on ecosystems. The Future Role of Pesticides explores the role of chemical pesticides in the decade ahead and identifies the most promising opportunities for increasing the benefits and reducing the risks of pesticide use. The committee recommends R&D, program, and policy initiatives for federal agriculture authorities and other stakeholders in the public and private sectors. This book presents clear overviews of key factors in chemical pesticide use, including: Advances in genetic engineering not only of pest-resistant crops but also of pests themselves. Problems in pesticide useâ€"concerns about the health of agricultural workers, the ability of pests to develop resistance, issues of public perception, and more. Impending shifts in agricultureâ€"globalization of the economy, biological "invasions" of organisms, rising sensitivity toward cross-border environmental issues, and other trends. With a model and working examples, this book offers guidance on how to assess various pest control strategies available to today's agriculturist.
