Some substances which are known or suspected carcinogens are aniline, chloroform, benzyl chloride, chromates of lead and zinc, hydrazine etc. Ninhydrin - the reagent used in biological and biochemical tests for the presence of amino acids and proteins, is also thought to be a possible carcinogen, but this has yet to be confirmed.
