How can a chemical we need on a daily basis to keep us healthy be fatal at a different dose? Why should elements that are intrinsically dangerous be used in medicine? How did poisoners use the chemical properties of chemicals to cover their tracks? Emsley gives detailed histories of five of the most toxic elements - arsenic, antimony, lead, mercury, and thallium, highlighting some of the most famous murders and how the murderers used the chemical properties of elements to hide what they were doing. He shows how the elements have been behind many modern day environmental catastrophes including accidental mass poisonings from lead and arsenic, and the Minamata Bay Disaster in Japan. The array of fascinating stories shows how chemicals have impacted the lives of people ranging from the Greeks and Romans to Newton, Napoleon, Lucrezia Borgia, Mozart, Nelson Mandela, and Saddam Hussein. Emsley also touches on subjects close to home: cot deaths, laxatives, venereal disease, alleged cures for acne, hangovers, and insanity.

What is the most common element in the universe? Can you name the noble gases? Everything we see around us is made of chemical elements, but most of us know little about them. Penned by award-winning science writer John Emsley, Nature''s Building Blocks explains the what, why and wherefore of the chemical elements. Arranged alphabetically, from Actinium to Zirconium, it is a complete guide to all 115 of those that are currently known, with more extensive coverage of those elements we encounter in our everyday life. The entry on each element reveals where it came from, what role it may have in the human body, and the foods that contain it. There are also sections on its discovery, its part in human health or illness, the uses and misuses to which it is put, and its environmental role. Readers discover that the Earth consists of around 90 elements, some of which are abundant, such as the silicon and oxygen of rocks and soils, while some are so rare that they make gold seem cheap. Our own bodies contain about 30 elements, some in abundance, some in trace amounts; some vital to our health, and some that are positively harmful. A list of the main scientific data, and outline properties, are given for every element and each section ends with an "Element of Surprise," which highlights some unexpected way in which each element influences our everyday life. Both a reliable reference source and a high browsable account of the elements, Nature''s Building Blocks offers a pleasurable tour of the very essence of our material world.

The incredible ""glowing"" history of the ""Devil''s element ""phosphorus Discovered by alchemists, prescribed by apothecaries, exploited by ninth-century industrialists, and abused by twentieth-century combatants, the chemical element phosphorus has fascinated us for more than three centuries. It may even be the cause of will-o''-the wisps and spontaneous human combustion! Now John Emsley has written an enthralling account of this eerily luminescent element. Shining with wonderful nuggets-from murders-by-phosphorus to a match factory strike; from the firebombing of Hamburg to the deadly compounds derived from phosphorus today-The 13th Element weaves together a rich tableau of brilliant and oddball characters, social upheavals, and bizarre events.

Molecules of Murder is about infamous murderers and famous victims; about people like Harold Shipman, Alexander Litvinenko, Adelaide Bartlett, and Georgi Markov. Few books on poisons analyse these crimes from the viewpoint of the poison itself, doing so throws a new light on how the murders or attempted murders were carried out and ultimately how the perpetrators were uncovered and brought to justice. Part I includes molecules which occur naturally and were originally used by doctors before becoming notorious as murder weapons. Part II deals with unnatural molecules, mainly man-made, and they too have been dangerously misused in famous crimes. The book ends with the most famous poisoning case in recent years, that of Alexander Litvinenko and his death from polonium chloride. The first half of each chapter starts by looking at the target molecule itself, its discovery, its history, its chemistry, its use in medicine, its toxicology, and its effects on the human body. The second half then investigates a famous murder case and reveals the modus operandi of the poisoner and how some were caught, some are still at large, and some literally got away with murder. Molecules of Murder will explain how forensic chemists have developed cunning ways to detect minute traces of dangerous substances, and explain why some of these poisons, which appear so life-threatening, are now being researched as possible life-savers. Award winning science writer John Emsley has assembled another group of true crime and chemistry stories to rival those of his highly acclaimed Elements of Murder.

What is it in chocolate that makes us feel good when we eat it? What''s the molecule that turns men on? What''s the secret of Coca-Cola? In this fascinating book, John Emsley takes us on a guided tour through a rogue''s gallery of molecules, some harmful some pleasant, showing how they affect our lives. There are eight galleries in all, full of individual portraits on molecules that are to be found on a daily basis in the home, the environment, and in our bodies–from caffeine to teflon, nicotine to zinc. Find out how Mozart met his death, how Hitler could have saved the Third Reich from defeat, and many more interesting snippets in this highly entertaining, and often surprising book. ''A broad audience, regardless of whether it has a background in chemistry, will enjoy browsing and reading it.'' Nature ''a fine example of popular science writing at its best. It is educational, interesting, may prove inspirational and therefore deserves to find a very wide readership.'' THES ''highly readable and entertaining'' New Scientist

This book explains to the general reader the roles of chemistry in various areas of life ranging from the entirely personal to the worryingly global. These roles are currently not widely appreciated and certainly not well understood. The book is aimed at educated laypeople who want to know more about the world around them but have little chemical knowledge. The themes relate to the importance of chemistry in everyday life, the benefits they currently bring, and how their use can continue on a sustainable basis. Topics include: Health - conquering the diseases and stresses which still threaten us. Food - the role of agrochemicals and food chemists. Water - drinking water; the seas as a resource of raw materials. Fuels - what are they and from what are they made? Plastics - what are the used for and can they be sustainable? Cities - what role has chemistry in modern life? Sport - chemistry has changed the game. The world stands at a crossroads. What route to the future should we take? The road to a sustainable city beckons, but what effect will this have on chemistry, which appears so dependent on fossil resources? Its products are part of everyday living, and without them we could regress to the world of earlier generations when lives were blighted by disease, famines, dirt, and pain. In fact the industries based on chemistry the chemical, agrochemical, and pharmaceutical industries could be sustainable and not only benefit those in the developed world but could be shared by everyone on this planet and for generations to come. This book shows how it might be achieved.

Vanity, Vitality, and Virility is a fascinating portrait gallery of chemicals involved in our everyday life, from Viagra and selenium to whispering asphalt, nappies, and chewing gum. While it will not advise you what to do if you want to improve your looks, your health, your peace of mind or your sex life, it explains the science behind many of the products that claim to be able to do just that. Chemistry is too often associated with poisonous gases and strange bubbling solutions, yet it is all around us, and inside us too. Renowned science communicator John Emsley lifts the lid on the secrets inside the products we use every day.

John Emsley''s unusual study traces the history and development of the use of phosphorus, an autocombustive element that was discovered long before humans were responsible or capable of controlling its awesome power.

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.

Another fascinating title from best-selling author Emsley on grooming, health, food and sex, while discussing recent advances in chemistry and their impact on our everyday lives. Includes many classic examples and future prospects, written in an easily comprehensible style.

Hand cream, detergent, shower gel, toothpaste, toilet cleaner, air freshener, lipstick, perfume, low-fat spread, painkiller, diet drink, insect repellent... hundreds of everyday products that make our lives so much better than those of our forebears. And yet most of us know little about the ingredients they contain and why they deliver the benefits we enjoy. Some people find it worrying when they examine the list of ingredients on a packaging label, because all they read may be unintelligible names or E numbers. It appears to be just chemicals, chemicals, chemicals. The aim of this book is to examine the ingredients more closely and explain the reasons for their being used. Start reading and stop worrying. Chemistry at Home has been written by award-winning popular science writer and chemist, John Emsley, using non-technical language. The book has 12 chapters, each devoted to the kinds of products we are likely to find around the home, including in the garage and the garden shed. Chemistry at Home also includes a glossary which gives more technical information about the molecules mentioned in the book.
