title: Toxins and carcinogens in the environment: an observation in the tropics.
abstract: The incidence of primary liver cancer in the countries of tropical Africa is the highest in the world. There is a growing belief that the relatively high prevalence of hepatocellular carcinoma in Nigeria may have a multiple chemical factor etiology in such forms as food contaminants, herbal teas, and environmental chemicals. Major chemical toxins and carcinogens that have been identified so far in the tropical environment include sapotoxin, cycasin, mushroom toxin, capsaicin, oxalic acid, prussic acid, fluorooleic acid, N-nitroso compounds, aflatoxin, palmotoxin, pyrrolizidine alkaloids, quinine, DDT, and cyclamate.
