Environmental Fate and Safety Management of Agrochemicals discusses residue analysis, environmental fate and safety management, environmental risk assessment, metabolism, resistance and management, and advances in formulation and application technology from the academic, government, and industry perspective.
Meaningful ecological and environmental risk assessment of pest control agents is possible only when accurate and credible metabolic and environmental fate data is available. The advent of affordable and sensitive liquid chromatography/mass spectrometry (LC/MS) has greatly increased our ability to detect environmentally relevant metabolites and degradation products following the application of these materials. Furthermore, ecological risk assessment and monitoring of pesticide resistance in field populations has become more feasible and cost effective by employing hig-hroughout molecular diagnostic techniques on the genetic leve3l and LC/MS techniques on the proteomic and meabolomic levels.
Efficient formulations and application technologies have greatly reduced the amount of materials that are required to achieve effective pest control and hence reduce their ecological and environmental impacts. Controlled release, stabilization and dispersion technologies have provided the pest manager with new tools that allow them to use necessary pest control options in "best management strategies."

The book gives an overview of the current state-of-the-art concerning the activation and dissolution of cellulose in a broad variety of solvents. Research on this topic can lead to new pathways for the utilization of the most abundant terrestrial biomolecule and may therefore be the basis for new green strategies towards advanced materials. Leading scientists in the field show different conceptions for the solubilization of cellulose. The long history and groundbreaking developments in the field of polymer chemistry, which are related to this subject, have lead to timely alternatives to already established methods. In addition to discussing attempts for the optimization of known dissolving procedures, this book also details new solvent systems. New solvents include inorganic and organic salt melts (ionic liquids), new aqueous media, multi-component organic solvents and the dissolution under partial derivatization of the polysaccharide. The opportunities and the limitations of the solvents are demonstrated, with a particular emphasis on the stability of the solutions and a possible recycling of the solvent components.
This book illustrates that the new procedures for cellulose dissolution can lead to a huge number of unconventional superstructures of regenerated cellulose material, such as fibers and polymer layers with a thickness in the nanometer range or aerogels, i.e. regenerates with a highly porous character and a large surface. Moreover, cellulose blends can be generated via solutions. The book also contains chapters that show the amazing potential of solvents for defined modification reactions on the cellulose backbone. On one hand, it is possible to synthesize known cellulose derivatives with new substitution patterns both on the basis of the repeating unit and along the polymer chain. On the other hand, completely new derivatives are presented which are hardly accessible via heterogeneous reactions. Consequently, the book is intended to give a comprehensive overview of procedures for dissolution of cellulose. It is of interest for scientists new in the field but is also a timely summary of trends for experts who are looking for new approaches for problems related to cellulose shaping or chemical modification.

One of the great challenges of the 21st century is that of sustainability. This book aims to provide examples of sustainability in a wide variety of chemical contexts, in hope of laying the groundwork for cross-divisional work that might be possible in the future to address the important issue of sustainability. In doing so, the editors look at both the questions chemistry is asking right now related to sustainability as well as the questions chemistry SHOULD be asking about sustainability. The world is facing interrelated global challenges of energy, food, water, and human health. Solving these daunting challenges will require global systems thinking and proactive local action. No ONE company, academic institution, non-profit or government agency can accomplish this task alone, but it starts with education at all levels. This book addresses the need for better chemical education on the subject of sustainability.

(2) In books where there are images such as portraits, maps, sketches etc We have endeavoured to keep the quality of these images, so they represent accurately the original artefact. Although occasionally there may be certain imperfections with these old texts, we feel they deserve to be made available for future generations to enjoy.

Hydraulic Fracturing in the Karoo: Critical Legal and Environmental Perspectives explores a broad-ranging set of questions related to proposed hydraulic fracturing or `fracking' in the Karoo. The book is multidisciplinary, with contributors including natural scientists, social scientists, and academics from the humanities, all concerned with the ways in which scientific facts and debates about fracking have been framed and given meaning. The work comprises four parts: Part 1 provides an international, legal, energy, economic, and revenue overview of the topic. Part 2 has a physio-geographic theme, with chapters on the inter-related aspects of water, geology, geo-hydrology, seismicity and biodiversity, as well as archaeological and palaeontological considerations. Part 3 focuses on public health, and sociological and humanities-related aspects, and Part 4 addresses the relevant laws, emphasising their implementation and the role of governance. The underlying theme of Hydraulic Fracturing in the Karoo: Critical Legal and Environmental Perspectives is one of caution. The book emphasises the need for collaboration between the natural and social sciences and the responsibilities of those charged with the implementation and governance of the fracking enterprise if South Africa hopes to effectively manage fracking at all.

The provision of safe drinking water and the protection of public health and the environment through the treatment of wastewaters is increasingly informed by risk-based decision-making. Aspects of utility management such as process design and optimisation, asset management and compliance monitoring rely on a mature understanding of process risk within a broader context of business and environmental risk management. For operators, risk management is now regarded as a key business function. Understanding risk and being able to implement risk management is critical to the provision of safe drinking water. As part of a move towards a more strategic, forward looking approach to utility management, the IWA is promoting a risk-based approach to water utility management, from catchment to tap, through the implementation of the Bonn Charter (2004). Why manage risk? Basic probability and statistics Process risk and reliability analysis Assessing risks beyond the unit process boundary Regulating water utility risks Business risk management for water and wastewater utilities Managing opportunity and reputational risk Embedding better decision-making within utilities Having provided rationale for the importance of risk management, the text begins with the familiar territory of unit processes and process reliability. It then broadens out to consider, first environmental then organisational risk management. The final sections are concerned with better utility decision-making. The book has been designed for individual self-paced study. Each section of the text gives step-by-step learning in a particular subject, that includes an approximation of how long you will need to spend on that section and provides key points that highlight the principles of the different sections. Each unit includes exercises to help understand the material in the text as well as self-assessment questions to test your understanding and text references.

Flocs in Water Treatment is the first of its kind - serving as a valuable aide-memoire for scientists, process engineers and other professionals engaged in water treatment. The framework described in Flocs in Water Treatment can also be applied to aggregated solids found both in the natural environment, and within a broad range of industries. Flocs (aggregated solid matter) resulting from the combined influence of coagulation and flocculation play a vital role in solid-liquid separation processes. The design and operation of water treatment plants demands a proper understanding of the ways in which flocs affect treatment systems and how their properties can be manipulated to increase treatment efficiency. Flocs in Water Treatment provides a comprehensive account of the ways in which flocs are formed, their characterization, and how they behave in practice. Flocs are complex entities, whose properties defy easy description and measurement. In spite of this, the authors provide a clear and discerning account of the current state of knowledge; this is rooted in science and draws on many disciplines. Based on their experiences in research and the workings of full scale treatment plants, the authors offer candid advice on tasks such as the measurement of floc properties and guidance on problems involving the use of chemicals for controlling floc properties within treatment systems.

Ozone, an important trace component, is critical to life on Earth and to atmospheric chemistry. The presence of ozone profoundly impacts the physical structure of the atmosphere and meteorology. Ozone is also an important photolytic source for HO radicals, the driving force for most of the chemistry that occurs in the lower atmosphere, is essential to shielding biota, and is the only molecule in the atmosphere that provides protection from UV radiation in the 250-300 nm region. However, recent concerns regarding environmental issues have inspired a need for a greater understanding of ozone, and the effects that it has on the Earth's atmosphere. The Mechanisms of Reactions Influencing Atmospheric Ozone provides an overview of the chemical processes associated with the formation and loss of ozone in the atmosphere, meeting the need for a greater body of knowledge regarding atmospheric chemistry. Renowned atmospheric researcher Jack Calvert and his coauthors discuss the various chemical and physical properties of the earth's atmosphere, the ways in which ozone is formed and destroyed, and the mechanisms of various ozone chemical reactions in the different spheres of the atmosphere. The volume is rich with valuable knowledge and useful descriptions, and will appeal to environmental scientists and engineers alike. A thorough analysis of the processes related to tropospheric ozone, The Mechanisms of Reactions Influencing Atmospheric Ozone is an essential resource for those hoping to combat the continuing and future environmental problems, particularly issues that require a deeper understanding of atmospheric chemistry.

As the quantity and quality of inland water sources decline, more coastal municipalities are looking at seawater desalination as a potential source of drinking water. The Long Beach Water Department (LBWD) developed an alternative technology to desalt seawater by using dual-staged nanofiltration (NF2). This novel NF system treats the first-stage permeate through a second stage in order to produce finished water with salinity levels that meet drinking water standards. Three commercially-available NF membranes were selected for this study based upon their designation as NF membranes by the manufacturers and their salt rejection characteristics. Results from the bench-scale evaluation were integrated in a performance-predicting model, which was subsequently calibrated against the results obtained with an 8-gpm pilot unit. The pilot-test plan considered the impact of temperature, pressure, and array configuration on permeate water quantity and quality. The percentage of desalinated water that could be blended into LBWD's distribution system was determined by taking into account the issues of disinfection by-product (DBP) formation, disinfectant residual, and corrosivity. Finally, viral challenge tests were considered to verify the inherent redundancy of the system and the impact that recycling streams would have on virus accumulation.
