At this time we know thousands of organofluorine compounds and many of them are very toxic for humans (1). Mainly fluoroacetic acid and many other alifatic monofluoro compounds satisfied criteria of reliable poisons (2) and several these compounds were examined during the last war for possible use as chemical warfare agents (3-5). Author of this article hopes that more widespread knowledge of these very dangerous compounds may act as a deterrent to their illegal use and that concern may be stimulated in the search for more satisfactory methods of medical treatment.
