Mercapturic acids of acrylamide and glycidamide as biomarkers of the internal exposure to acrylamide in the general population

The median levels in smokers (n = 13) were found to be about four times higher than in non-smokers (n = 16) with median levels of 127 μg/l versus 29 μg/l for AAMA and 19 μg/l versus 5 μg/l for GAMA. Therefore cigarette smoke proved to be an important source of acrylamide exposure. The level of AAMA in the occupationally non-exposed collective (n = 29) ranged from 3 to 338 μg/l, the level of GAMA from
