Polycyclic Aromatic Hydrocarbons (PAHs) in “Yerba Mate” (Ilex paraguariensis) Fractions
The aim of this study was to evaluate polycyclic aromatic hydrocarbons (PAHs) contamination, distribution, and toxicity in “yerba mate” fractions, and to propose actions to reduce its pollution. Sixteen PAHs were quantified using a recently developed methodology by HPLC-DAD/FLD, obtaining recoveries...
