The author's objective in writing this book was not to elaborate on the vast chemistry of the element, but to try to reveal to the general reader how the element and its compounds have become embedded in our social fabric, for good and for ill.

No other element comes close in this regard and he uses the word sociochemistry to describe this interface between society and chemistry.

    The topic of arsenic in the environment is discussed in depth - arsenic is all around us - in our soil, our water, and our food, and our bodies have adapted to its presence and it does not usually pose a problem. However, the natural presence of high concentrations of arsenic in drinking water currently threatens the lives of millions of people in India, Bangladesh, Mexico and elsewhere.

    It also covers mining and pesticide manufacturing which can lead to high local arsenic concentrations in soils, slag heaps and mine tailings which, when located close to human activities, can produce human health risks.
