For more than a century, national and international governing bodies have had some involvement in regulating the quality and safety of food during production and delivery. Since the beginnings of this "modern" food regulation in the early 20th century, the way that food is produced, packaged and distributed has changed drastically. It is difficult to determine if technological advances in the areas of polymer science, refrigeration, and transportation have driven the globalization of the food supply or if the food industry has drawn from these technologies to satisfy consumer's desire and need. Ensuring the safety of food requires a complex and ever-changing set of interactions between producers, distributors, consumers and regulators. As advances are made in packaging and food additives, as food distributions systems evolve to meet consumer needs, or as these respond to environmental and population changes, adjustments to regulatory systems may become necessary. Analytical, environmental and materials chemistry can often play important roles in responding to these changes and in continuing to help with the improvement of food safety and security. These five co-editors bring their respective expertise to the subject of the food system and the chemical advancements behind it.

Water is the most crucial material for human survival, after air. Without water, life would not be possible. It is important to know how much water is available to us and how much water is polluted. We need to monitor pollutants vigorously, both at point and nonpoint sources, using advanced analytical techniques that can monitor ultra-trace amounts of contaminants. Water reclamation is an absolute necessity today because we have contaminated our surface water, and even groundwater in some cases, to a point that it is not clean enough for drinking or cooking. Most importantly, water must be used judiciously, and equal treatment must be paid to the reclamation and treatment of contaminated water. This book provides information on various global water challenges and solutions. We face many water challenges in terms of availability, quality, and sustainability (Chapter 1). There is an urgent need to find ways to make water more sustainable. To achieve this objective, we will have to address scientific, technical, economic, and social issues.

Separations of Water Pollutants with Nanotechnology, the latest volume in the Separation Science and Technology series, offers new solutions for remediating water pollution utilizing nanomaterials with separation methods. Current water purification methods are unsuitable, inconvenient or expensive, so there is a need for new and better processes and techniques. Nanomaterials can purify water by removing pollutants such as heavy metals, pathogens, organic compounds, inorganic compounds, pharmaceuticals, and chemicals of emerging concern. These can effectively replace membrane-based methods if the right expertise is developed-this book helps separation scientists do just that. Existing water treatment problems can be solved by applying a nanotechnology-based processes: antimicrobial nanotechnology, zero-valent iron nanoparticles, nanoadsorbents, nano-enhanced membranes, nanometal oxides, and nano photocatalysts. The current literature places emphasis on materials chemistry rather than the separation methods used for water purification. This new volume presents a collection of chapters that deal with remediation based on separation chemistry.

Evaluating Water Quality to Prevent Future Disasters, volume 11 in the Separation Science and Technology series, covers various separation methods that can be used to avoid water catastrophes arising from climate change, arsenic, lead, algal bloom, fracking, microplastics, flooding, glyphosphates, triazines, GenX, and oil contamination. This book provides a valuable resource that will help the reader solve their potential water contamination problems and help them develop their own new approaches to monitor water contamination.

Advances in Water Purification Techniques: Meeting the Needs of Developed and Developing Countries provides a variety of approaches to water purification that can help assist readers with their research and applications. Water contamination problems occur frequently worldwide, hence the most updated knowledge on water purification systems can be helpful in employing the right type of filter or other mechanism of decontamination. The problems with arsenic contamination of water in Bangladesh and the lead problem in Flint, Michigan remind us of the need to monitor water pollution rigorously, from both point and non-point sources.

How will chemists of the future balance competing concerns of environmental stewardship and innovative, cost-effective product development? For chemists to accept the idea that environmental quality and economic prosperity can be intertwined, the concept of the food-energy-water nexus must first be integrated into underlying thought processes. Food, Energy and Water: The Chemistry Connection provides today's scientists with the background information necessary to fully understand the inextricable link between food, energy and water and how this conceptual framework should form the basis for all contemporary research and development in chemistry in particular, and the sciences in general.

Capillary electrophoresis (CE) is a powerful analytical technique that is widely used in research and development and in quality control of pharmaceuticals. Many reports of highly efficient separations and methods have been published over the past 15 years. CE offers several advantages over high-pressure or high-performance liquid chromatography (HPLC). These include simplicity, rapid analysis, automation, ruggedness, different mechanisms for selectivity, and low cost. Moreover, EC requires smaller sample size and yet offers higher efficiency and thus greater resolution power over HPLC. These characteristics are very attractive in research and development, even more so in pharmaceutical quality control (QC) and stability monitoring (SM) studies. This book will provide busy pharmaceutical scientists a complete yet concise reference guide for utilizing the versatility of CE in new drug development and quality control.
- Provides current status and future developments in CE analysis of pharmaceuticals.

The United States Food and Drug Administration (FDA) and other regulatory bodies around the world require that impurities in drug substance and drug product levels recommended by the International Conference on Harmonisation (ICH) be isolated and characterized.
Identifying process-related impurities and degradation products also helps us to understand the production of impurities and assists in defining degradation mechanisms. When this process is performed at an early stage, there is ample time to address various aspects of drug development to prevent or control the production of impurities and degradation products well before the regulatory filing and thus assure production of a high-quality drug product.
This book, therefore, has been designed to meet the need for a reference text on the complex process of isolation and characterization of process-related (synthesis and formulation) impurities and degradation products to meet critical requlatory requirements.
It's objective is to provide guidance on isolating and characterizing impurities of pharmaceuticals such as drug candidates, drug substances, and drug products. The book outlines impurity identification processes and will be a key resource document for impurity analysis, isolation/synthesis, and characterization.
- Provides valuable information on isolation and characterization of impurities.
- Gives a regulatory perspective on the subject.
- Describes various considerations involved in meeting regulatory requirements.
- Discusses various sources of impurities and degredation products.
