Abstract

Benzo(a) pyrene, aflatoxin, sterigmatocystin and six kinds of nitrosamine and their precursors (secondary amine) in 36 specimens of source drinking water collected from stomach cancer prevalent areas of Zanhuang County during the autumn and spring periods were determined quantitatively with high performance liquid chromatography. Results showed drinking water for local residents was significantly contaminated with benzo(a) pyrene, with an average of 0.0148 microgram/L and the highest one of 0.0305 microgram/L, and especially in the autumn, simultaneous contamination with nitrosodimethylamine, nitrosodiethylamine, and nitrosodipropylamine could be found, with proportions of 38.5%, 76.9% and 76.9%, respectively. Aflatoxin B1, and G1 could also be found in drinking water in the autumn, but no sterigmatocystin could be detected.
