Determination of polycyclic aromatic hydrocarbons in tea infusions samples by high performance liquid chromatography with fluorimetric detection
This study focuses on the contamination of 15 polycyclic aromatic hydrocarbons (PAHs) ,
recommended by the US Environmental Protection Agency, in 10 tea brands distributed in Italy.
Analysis were carried out with a procedure based on saponification, liquid-liquid extraction and
PAHs determination by high performance liquid chromatography with fluorescence detector. A
comparison with ultrasonic extraction in bath water was also reported. Contamination is expressed
