Green Analytical Chemistry


Book Description

Concerns about environmental pollution, global climate change and hazards to human health have increased dramatically. This has led to a call for change in chemical processes including those that are part of chemical analysis. The development of analytical chemistry continues and every new discovery in chemistry, physics, molecular biology, and materials science brings new opportunities and challenges. Yet, contemporary analytical chemistry does not consume resources optimally. Indeed, the usage of toxic chemical compounds is at the highest rate ever. All this makes the emerging field of green chemistry a “hot topic” in industrial, governmental laboratories as well as in academia. This book starts by introducing the twelve principles of green chemistry. It then goes on to discuss how the principles of green chemistry can be used to assess the ‘greenness’ of analytical methodologies. The ‘green profile’ proposed by the ACS Green Chemistry Institute is also presented. A chapter on “Greening” sample preparation describes approaches to minimizing toxic solvent use, using non-toxic alternatives, and saving energy. The chapter on instrumental methods describes existing analytical approaches that are inherently green and making non-green methods greener. The final chapter on signal acquisition describes how quantitative structure-property relationship (QSPR) ideas could reduce experimental work thus making analysis greener. The book concludes with a discussion of how green chemistry is both possible and necessary. Green Analytical Chemistry is aimed at managers of analytical laboratories but will also interest teachers of analytical chemistry and green public policy makers.

The Importance of Packaging Design for the Chemistry of Food Products


Book Description

This Brief defines reliable correlations between the food packaging design and its chemical features in terms of an 'integrated food product' (the synergistic union composed of the edible content and its container). A good design, as described in this Brief, implies the best choices from a series of possibilities, taking into account economical and commercial influences or limitations in the production and processing chain and the chemical interactions that can arise between the food containers and the contained edible material. This Brief highlights how the different requirements can be combined, while avoiding dangerous food risks originating from the chemical interaction between the container and the product. Different designs are critically analysed with relation to the effect on contained foods. The influences and resulting consequences of different possible food packaging designs are highlighted and discussed in selected case studies for some every-day products (like potato chips).

Topics such as toxicological risks, the importance of labelling, technical and material safety data sheets, risk categories (e.g. fire, explosion, unforeseen chemical reactions, etc.), safe use of hazardous chemicals, prevention procedures, and emergency planning in laboratories and industrial areas are also covered. In closing, readers will learn more about the future behaviour of food-production workers regarding chemical handling and approved uses, especially in light of the recent REACH obligations. Given its scope, the book will appeal not only to researchers interested in food production, food safety, risk prevention and public health, but also to professionals involved in quality control and risk assessment in the food and beverage industry.
