8 The Breadth of Modern Toxicology 19 In the late twentieth century, the growing industrial strength of the Asian economies helped spur the growth of toxicology and occupational health in Japan, Korea, Taiwan and elsewhere. Major legislative initiatives to protect the health of workers in these countries included implementation of the Japanese Chemical Substances Control Law in 1973, the Korean Toxic Chemicals Control Act in 1991 and the Chinese Provision on Environmental Administration of New Chemical Substances in 2010.

The word poison is widely used for this purpose during everyday life, with its popularity traceable to ancient times. The Father of Modern Toxicology, Mathieu Orfila, also found the term suitable when writing the introductory chapter to his famous 1813 General Treatise of Toxicology, ‘The name of poison is given any substance, which, taken inwardly, in a very small dose, or applied in any kind of manner to a living body, impairs health, or destroys life’. Despite its longstanding pedigree, the term poison is not widely used as an umbrella term in modern toxicology because it may convey the misleading connotation that the world contains just two types of chemicals: ‘poisons’ and ‘nonpoisons’.

In subsequent days and weeks, national governments around the world placed bans on the drug. Since many victims – perhaps 40 % or so – died in the early months of life, precise estimates of the number of children affected by thalidomide are hard to obtain, but a figure of 10,000 or so victims is commonly accepted. The then-largest medical damages court case in German history followed, but with the passage of time public interest in the case subsided. For thousands of families, however, the pain of living with the carnage inflicted by thalidomide would have a lasting impact.
