Exposure assessment to areca alkaloids in the Chinese populations through areca nut chewing.

ABSTRACT: Chewing areca nuts is popular in China. Areca alkaloids are the major toxic compounds in areca nuts. In this study, the levels of four areca alkaloids (i.e. arecoline, arecaidine, guvacoline and guvacine) in 119 areca nut samples were analyzed and 3030 areca nut consumption questionnaires were collected to investigate the exposure to areca alkaloids in the Chinese populations through areca nut chewing. The levels of arecoline, arecaidine, guvacoline and guvacine in different areca nut products were 0.46-4.97 mg/g, 0.57-7.51 mg/g, 0.08-1.44 mg/g and 0.03-8.48 mg/g, respectively. Chewing fresh areca fruits was the main source of arecoline and the total areca alkaloids exposure. The estimated daily intake (EDI) of arecoline and the total areca alkaloids for the Chinese populations were 1.126
