How can a plant as beautiful as the foxglove be so deadly and yet for more than a century be used to treat heart disease? The same is true of other naturally occurring molecules as will be revealed in this current book by award-winning author and chemist, John Emsley. More Molecules of Murder follows on from his highly-acclaimed earlier book Molecules of Murder, and again it deals with 14 potential poisons; seven of which are man-made and seven of which are natural. It investigates the crimes committed with them, not from the point of view of the murderers, their victims, or the detectives, but from the poison used. In so doing it throws new light on how these crimes were carried out and ultimately how the perpetrators were uncovered and brought to justice. Each chapter starts by looking at the target molecule itself, its discovery, its chemistry, its often-surprising use in medicine, its effects on the human body, and its toxicology. The rest of the chapter is devoted to murders and attempted murders in which it has been used. But, be reassured that murder by poison is not the threat it once was, thanks to laws which restrict access to such materials and to the skills of analytical chemists in detecting their presence in incredibly tiny amounts.

The very important topic of referencing and calibration in CSIA is clearly described. This differs from approaches used in quantitative analysis and is often difficult for the newcomer to comprehend. Examples of successful applications of CSIA in food authenticity, forensics, archaeology, doping control, environmental science, and extraterrestrial materials are included. Applications in isotope data treatment and presentation are also discussed and emphasis is placed on the general conclusions that can be drawn from the uses of CSIA. Further instrumental developments in the field are highlighted and selected experiments are introduced that may act as a basis for a short practical course at graduate level.

Over the last 150 years, the Public Analyst profession has hidden its light under a bushel, with the notable exception of Fredrick Accum, one of the first Public Analysts who published the names and addresses of food adulterers, this group of chemists has quietly protected the public from food fraud and adulteration. Using their forensic skills to find traces of poison and other deleterious materials in our food and guiding the Courts and legal profession through complex scientific evidence, it has undersold itself to the public. It is time to tell their story with this collection of memoirs from many practising and retired Public Analysts. Their accounts of samples submitted to them, how they analysed them, and the tales that unfolded, make for a fascinating insight into the field. This is a timely publication, as funding for this area continues to fall, to the concern of many not just in the UK but throughout Europe. Yet, whilst food adulteration may not be as rife as it was 150 years ago, food fraud and adulteration is now on a global scale with improved communications, the fear of adulteration is probably larger than ever. This funding position does not sit well alongside levels of public interest that have never been higher in food, science in general, and forensic science. And yet research is still needed to find future strategies to maintain a vital service to protect the public and it is important to raise the profile of the role of the Public Analyst, now more than ever, This book, which is not intended as a text book but as a light read, will achieve this aim while simply telling the stories of a collection of Public Analysts, things they have found in food and other materials and their memoirs and anecdotes. It will appeal to those who watch programmes such as Crime Scene Investigates and anyone with an interest in forensic science and science in general.

Continuous coverage on some topics such as theoretical and physical aspects of nuclear shielding is balanced by the desire for coverage on newer topics like applications in biological systems and materials science. For those wanting to become rapidly acquainted with NMR or seasoned practitioners, this is an invaluable source of current methods and applications.

Although toxic in large doses, selenium is an essential trace mineral in the animal diet and in some plants. It has a role in making antioxidant enzymes and a particular role in the functioning of the thyroid gland. This volume examines the chemical activity of selenium and its functional health effects eg towards cancers, in the heart and brain. It also covers other areas such as functional food enrichment, whole body metabolism, and the effects of selenium deficiency on health. Part of The Food and Nutritional Components in Focus series, this edited volume pools knowledge across scientific disciplines in a way that increases its applicability to a wide range of audiences. Victor Preedy's own distinguished career in nutritional science has made him a prolific author of research articles and books in this area, and this project fills a gap in providing comprehensive synopses of food substances. Chemists, analytical scientists, forensic scientists, food scientists, as well as course lecturers will all benefit from this interdisciplinary title written by international experts in this area.

Calcium's importance in health and disease is clear when listing its multiple roles in the body, which include building strong bones and teeth, vascular calcification, muscle function, hormonal regulation and maintaining a normal heartbeat.

Carnosine and anserine are two common histidine-derived dipeptides, also known as imidazole dipeptides, found in muscle and brain tissues of animals. Their dietary and nutritional significance lies in their antioxidant properties and a number of investigators are looking at other health benefits of the compounds. This volume surveys the current state of play in these and other areas of interest, including chemistry and biochemistry, immunology and cellular homeostasis. Chapters look in depth at some of the functions and effects in the body particularly with regard to exercise and fatigue, wound healing, cancer treatment and age-related diseases. Providing an up to date, interdisciplinary approach, this book is of great interest to researchers and professionals in chemistry, food science, nutrition, biochemistry, health sciences and sports sciences.

Electrochemical methods of chemical analysis have been widely used for many years, most especially the trusty pH electrode and conductivity meter, but also in the mass-manufactured glucose test strips which place electrochemical measurements into the hands of non-scientists. The purpose of this volume is to address advances that will enable new measurement strategies in the future. Surveying research and development advances based on new methods, materials and devices that achieve improved electroanalytical performances, this collection encompasses chip-based systems, through nanodomain approaches and soft interfaces. This book is a vital resource for graduate students and professional analytical chemists.
