Abstract
Butylated hydroxyanisole (I) is one of the most commonly used food antioxidants. Its use has been suggested to inhibit a variety of carcinogenic responses. The present study on the disposition kinetics of (I) in man indicates that contrary to previous reports, (I) undergoes significant Oβdemethylation in the body yielding a tertβbutyl hydroquinone. It is suggested that this metabolic conversion may be responsible for some of the in vivo activities of (I) against chemical carcinogens.

## Abstract In this study, butylated hydroxyanisole (BHA) and butylated hydroxytoluene (BHT) were used to determine the inhibition of arylamine __N__βacetyltransferase (NAT) activity and DNA adduct formation in human bladder tumour cell line Tβ24. The activity of NAT was measured by highβperformanc
