Detection of carcinogenic glutamic acid pyrolysis products in cigarette smoke condensate

Abstract
Carcinogenic glutamic add pyrolysis products were measured in condensate of cigarette mainstream smoke by HPLC. These carcinogens were found to be present in all brands of filter-tipped cigarette analyzed. The mean levels of 2-amino-6-methyldipyrido[1,2-a:3′,2 -d]imidazole and 2-aminodipyridol[l,2-a:3′,2′-d]imidazole in the cigarette mainstream smoke were 0.66 and 0.63 ng/cig respectively.
