High Levels of Carcinogenic Polycyclic Aromatic Hydrocarbons in Mate Drinks

Abstract
Background: Drinking mate has been associated with cancers of the esophagus, oropharynx, larynx, lung, kidney, and bladder. We conducted this study to determine whether drinking mate could lead to substantial exposure to polycyclic aromatic hydrocarbons (PAH), including known carcinogens, such as benzo[a]pyrene.
