Written by multidisciplinary experts in medicine, chemistry, and architecture, this book examines chemical sensitivity (CS). In 15 chapters fitted to 15 lectures, it discusses not only the medical explanation, but also the environmental factors of this hypersensitive reaction, such as chemistry and architectural aspects. The book overviews pollution-induced diseases such as Minamata Disease. It also points out the similarity of modern hypersensitivity syndromes to historical pollution diseases from the viewpoints of not only natural scientific aspects, but also social understanding of the disease.
