Substantiv

toxin - A toxic or poisonous substance produced by the biological processes of biological organisms.

Wikipedia Wiktionary dictionary logo

  • A toxin is a poisonous substance produced by living cells or organisms (although humans are technically living organisms, man-made substances created by artificial processes usually are not considered toxins by this definition). It was the organic chemist Ludwig Brieger (1849–1919) who first used the term 'toxin'. For a toxic substance not produced by living organisms, "toxicant" is the more appropriate term, and "toxics" is an acceptable plural.
